Most animal manure consists of feces. Common forms of animal manure include farmyard manure (FYM) or farm slurry (liquid manure). FYM also contains plant material (often straw), which has been used as bedding for animals and has absorbed the feces and urine. Agricultural manure in liquid form, known as slurry, is produced by more intensive livestock rearing systems where concrete or slats are used, instead of straw bedding. Manure from different animals has different qualities and requires different application rates when used as fertilizer. For example horses, cattle, pigs, sheep, chickens, turkeys, rabbits, and guano from seabirds and bats all have different properties.[1] For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds so horse manure can contain grass and weed seeds, as horses do not digest seeds the way that cattle do. Cattle manure is a good source of nitrogen as well as organic carbon.[2]Chicken ...
Alfalfa produces its own N; thus, the added N from the manure is not used efficiently. Alfalfa will use any N from manure with some compensation in the amount of N that it symbiotically fixes from the atmosphere. From an environmental perspective, manure N used by alfalfa in this manner is better than over-applications of manure N to corn or small grain acres. However, manure is often surface applied to alfalfa with little or no incorporation into the soil. This leaves manure vulnerable to being washed off the field during heavy precipitation events, thereby causing potential surface water concerns.. If manure is applied to alfalfa, an obvious concern to most alfalfa growers is the influence the N will have on competing weeds and grasses in the field. Research has shown that a well-fertilized field will benefit all plant species in the field, including weed germination and proliferation. Another indirect effect of applying manure to alfalfa fields is compaction of the soil and root crowns of ...
Manure can provide valuable nutrition to our soils in nitrogen (N), P, potassium (K), sulfur, trace minerals, and organic matter. Analysis of manure varies by animal species, type of production (growing vs lactation), type of bedding used, and manure storage system. Sampling the manure and submitting it to a certified laboratory for testing is necessary to determine the nutrient analysis. By using worksheets available on the University of Minnesota Extension website1 along with a manure analysis of 14% N, 11% P, and 7% K, the NPK value of manure can be determined compared to commercial fertilizer. Manure is usually more expensive to apply than commercial fertilizer and the aforementioned worksheet accounts for this. All too often, the livestock farmer selling manure does not receive a price reflecting manures fertilizer replacement value. Dairy pen-pack manure incorporated within 12 hours after application gives us 55% nitrogen availability the first year. When using the University of Minnesota ...
Phosphorus (P) losses from agricultural land is a serious environmental issue because of the impact of P on freshwater eutrophication (McDowell, et al., 2001). The movement of P from soil to surface water is impacted by P input to soil and manure management practices that impact P transport processes. Twenty-one natural runoff plots were established to monitor the effect of time and method of composted beef feedlot manure application and feed P input on net losses of bio-available P and sediment in surface runoff. Reducing feed P inputs resulted in a 33% reduction in manure P content. Runoff losses of P were reduced in direct proportion to feed P inputs. Runoff volume and sediment losses were lowest in the year s of compost application and we observed that a longer time interval between compost application date and spring runoff season resulted in increase sediment, runoff and P loss. Bray-PI extractable soil P (0-15cm) increased from 27 ppm prior to compost application up to 400 ppm in direct
Antibiotics are added to agricultural fields worldwide through wastewater irrigation or manure application, resulting in antibiotic contamination and elevated environmental risks to terrestrial environments and humans. Most studies focused on antibiotic detection in different matrices or were conducted in a hydroponic environment. Little is known about the transfer of antibiotics from antibiotic-contaminated irrigation wastewater and animal manure to agricultural soil and edible crops. In this study, we evaluated the transfer of five different antibiotics (tetracycline, sulfamethazine, norfloxacin, erythromycin, and chloramphenicol) to different crops under two levels of antibiotic-contaminated wastewater irrigation and animal manure fertilization. The final distribution of tetracycline (TC), norfloxacin (NOR) and chloramphenicol (CAP) in the crop tissues under these four treatments were as follows: fruit | leaf/shoot | root, while an opposite order was found for sulfamethazine (SMZ) and erythromycin

Manitoba Livestock Manure Management Initiative Project 05-01-05 "Bioactive Compounds in Swine Manure" Composted swine manure was examined for the presence of antibacterial and antifungal activities. While commercial composts show some antibacterial activity composted swine manure demonstrated inhibitory activity against Gram-positive bacteria and fungi. Weaker inhibitory activity against Gram-negative bacteria was also detected in composted swine manure. It is likely that these antimicrobial activities are due to compounds produced by bacteria or fungi present in the composted swine manure. An antifungal compound of possible commercial and agricultural significance is present in composted swine manure. Antibacterial agents of the same significance are also present. Introduction Manure is usually regarded by the public as a problem while farmers regard manure as a valuable commodity, as a fertilizer. Manure and composted manure are extremely complex bacterial ecosystems. Hundreds, probably ...
The interactive effect of biochar, cattle manure and nitrogen (N) fertilizer on the dynamics of carbon (C) mineralization and stabilization was investigated in a sandy soil amended with three sole biochar (0, 20 or 40 t ha−1) or manure (0, 13 or 26 t ha−1) and four combined biochar-manure levels (20 or 40 t ha−1 biochar plus 13 or 26 t ha−1 manure) with or without N fertilizer (0 or 90 kg ha−1) and CO2-C evolution measured over 54-d incubation period. Biochar application, solely or combined with manure resulted in lower applied C mineralized (ACM), indicating C sequestration in the soils. Negative attributable effect (AE) of co-application of biochar and manure on C mineralization was observed relative to the sole treatments. Both ACM and AE were negatively correlated with C/N ratio and mineral N content of the soil-mixtures (r ≥ - 0.573; p ≤ 0.01), indicating microbial N limitation. The double first-order exponential model described CO2-C efflux very well and indicated that ≥94% ...
In order to develop approaches for reducing the carbon footprint of the swine and dairy industries, it is important first to identify the methanogenic communities that drive methane emissions from stored manure. In this study, the metabolically active methanogens in substrate-starved manure samples taken from two dairy and one swine manure storage tanks were identified using [13C]-acetate and DNA stable-isotope probing (DNA-SIP). Molecular analysis of recovered genomic [13C]-DNA revealed that two distinct clusters of unclassified methanogen populations affiliated with the Methanoculleus genus, and the populations affiliated with Methanoculleus chikugoensis assimilated acetate-derived carbon (acetate-C) in swine and dairy starved manure samples, respectively. Furthermore, carbon flow calculations indicated that these populations were the primary contributors to methane emissions during these anoxic SIP incubations. Comparative analysis of mcrA gene abundance (coding for a key enzyme of ...
Duration: 1995 - 1997 Composting of dairy manure has not been a common practice, but there has been increasing interest in composting recently as a storage and handling method that requires less capital investment, reduces odor problems, etc. Little or no research has been conducted, at least in the U.S., to evaluate nutrient availability, ammonia emissions, or surface runoff losses from composted dairy manure when applied to perennial forages. The objective of this study was to evaluate the availability of nutrients, especially N, from composted dairy manure for grass hay production. This study was part of the liquid manure study described in Liquid Manure on Grass Hay to Improve Nutrient Use Efficiency, Yields and Quality. Compost was applied at three rates (10, 20 and 40 tons/acre) for two subsequent years. A fourth treatment was compost applied at the 40 ton rate only in the first year. Preliminary results indicate that yield response to compost was quite low (not much higher than the no ...
Authors Organization: (1) Institute of Joint Bioenergy, Nanjing University of Technology, Nanjing 210009;Jiangsu;China; (2) Cascade Clean Energy Inc. 10610 Morengo Drive, Cupertino, CA 95014 With the growth of animal farms around the world, animal manure is becoming a pollution resource especially to nearby populations. Chicken manure is the richest animal manure in nitrogen, phosphorous and potassium (N-P-K). The higher volatile nitrogen content is worse than to the atmosphere than other manures, and many pathogenic bacteria is harmful to peoples health. Anaerobic digestion of animal manure is a popular disposal method. However, because of higher nitrogen content and relatively lower carbon source, chicken manure is difficult in accomplishing a successful and rapid anaerobic digestion process with earlier acidification to affect the biogas production. Straw and many other crop biomass is one of crop wastes which composed of abundant organic carbon source. In this paper, we investigated the anaerobic
Complete article is available online.. PDF version is available online.. Objective: To examine the growth of aerobic bacteria in swine manure when used as manure additives for odor control.. Methods: Hydrogen peroxide was used as an oxygen provider added to the test manure at fixed time intervals to enhance the dissolved oxygen level in manure, simulating intermittent aeration.. Results: Adding hydrogen peroxide failed to establish an aerobic environment in the top liquid. The added aerobes could not outgrow the indigenous anaerobes even when the dissolved oxygen levels in the manure were raised for short intervals on a regular basis.. Implications: The frequency of running intermittent aeration in order to maintain an active aerobic flora requires further study. Without enough aeration, the effectiveness of microbial-based manure additives for odor control purposes in actual manure storage systems is questionable.. Keywords: manure, odor, microbes. ...

Modernization of the livestock industry has given rise to highly efficient production systems under one roof in place of the traditional pastured herd. These operations have also created new management challenges in the collection, storage and handling of large quantities of manure.. Manure contains nitrogen, phosphorus, inorganic salts, organic solids and microorganisms. All of these are potential contaminants of both surface and ground water. The runoff from poorly designed feedlots and manure storage facilities can be a direct source of surface water contaminants. Livestock allowed to stand in streams or ponds deposit manure directly into surface waters. Storage facilities (e.g., earthen or concrete pits, lagoons, etc.) that leak can be direct sources of large quantities of manure contaminants to ground water. Excessive or improperly timed manure applications on permeable soils can result in elevated nitrate levels in shallow ground water. Manure applications are also a source of phosphorus ...
Hydrothermal processing of swine manure is a novel technology that has shown very promising results in treating waste and producing oil. Oil yields of up to 70% were achieved in batch experiments. Since a continuous-mode process is more applicable for scale-up operations, a continuous hydrothermal process (CHTP) reactor system was developed. The effects of temperature, pressure, hydraulic residence time, and use of process gas, were evaluated to determine the optimal process condition. Products (i.e., oil, aqueous and gas) composition were determined to better understand the mechanics of the reaction process and to provide information for further developments. The CHTP, composed of a high-pressure slurry feeder, a process gas feeder, a continuous-stirred tank reactor, a products separation vessel, and process controllers, had a capacity of processing up to 48 kg of manure slurry per day. Results showed an interaction between operating temperature and pressure. The highest oil yield of 70% of ...
Manure from cattle fed distillers grain or corn diets was applied to fields, and the fields were subjected to rainfall simulation tests. Manure was added at three rates on till and no-till plots. Correlations between microbial transport and runoff characteristics were identified. Results indicate that diet affects phage but not bacterial transport from manure-amended fields.
It is acceptable to apply manure on established grasses, fields being seeded within two weeks of application, and berry fields if: T-Sum value in your area is greater than 200*; Soil temperature is greater than 5oC; Crop is actively growing (for established crops only); and Expected precipitation and manure applications will not create nutrient runoff to surface water or leaching below the root zone. Please continue to check you have enough manure storage to hold the average expected precipitation plus any excessive precipitation. Field stored solid agricultural wastes (except agricultural vegetation waste) MUST be COVERED from October 1 to April 1, inclusive. Check the Farmwest T-Sum to find the current T-sum value for your location. Please read the entire advisory for details and important information to assist in the decision-making process for manure application and storage ...
A thermochemical conversion (TCC) reactor was developed to process swine manure for waste reduction and energy production. The operating temperature and retention time are the two key parameters affecting the process. Carbon monoxide (CO) was employed as the reductive reagent. The investigated ranges of the operating temperature and retention time were 275C ~ 350C (corresponding operating pressures were 7 ~ 18 MPa) and 5 ~ 120 min, respectively. The pH value of the fresh swine manure (pH= 6.1), CO to VS ratio (CO:VS = 0.07 by weight or CO initial pressure p ini = 690 kPa), and total solids content (TS = 20%) were kept constant for all the experiments in this study. No extra catalyst was added in the experiments because of the presence of plentiful minerals and carbonates. The operating temperature was the most important factor affecting the TCC process. No substantial oil product yield was achieved unless the temperature reached 285C or above. Temperature higher than 335C led to solid char ...

Manure is fresh crap from an animal who is an herbivore. Compost is manure that has aged and will no longer harm the plants you put it on. Fresh Manure will "burn" your plants but once it has sat for a few years all that is left is the nutrition that plants need to grow. Manure is natural fertilizer, as is compost. There are also chemical and inorganic fertilizers. All manures can, with care, be used as fertilizers. Many fertilizers, though, are industrially-produced chemical compounds that have no resemblance whatsoever to manure.

In: Proceedings 242nd American Chemical Society National Meeting, Denver, CO; Aug. 28-Sept. 1, 2011. Abstract no. 248. Interpretive Summary: Technical Abstract: A research project was conducted to evaluate the efficacy of low-activity soybean peroxidase (SBP; 0.75 U/mg) and H2O2 for reducing emissions of odorous volatile organic compounds (VOC) from standard solutions (phenol and 4-methylphenol; 1 mM each) and swine manure slurry. VOC emissions were measured in a small wind tunnel. Air samples were collected in stainless steel sorbent tubes and analyzed by GC/MS. SBP (2000 mg/L) reduced 4-methylphenol and phenol emissions in standard solutions by 99 and 50%, respectively. The optimum H2O2 addition was 1.32 mM per mM phenolic substrate. Percent reduction of 4-methylphenol emission was about 65% in swine slurry with SBP addition ...
Pig manure is an excellent fertilizer and rich source of organic carbon and nitrogen compounds such organic nitrogen (O-N) (95% of total nitrogen) that is plant-unavailable-nitrogen (PUN) and mineralized nitrogen (about 1% of total nitrogen) such as ammonium (NH4+) and nitrate (NO3) that are plant-available-nitrogen (PAN). In addition, manure also contains two forms of estrogens: (i) poorly estrogenic thus essentially nontoxic conjugated estrogens (cEs) such as estrone (cE1), estradiol (cE2) and estriol (cE3); and (ii) highly estrogenic and toxic free estrogens (fEs) such as fE2, fE1 and fE3. This study showed that aerobic processing reduced concentrations of total carbon (TC), O-N, PAN and NH4+/NH3 ratio, transiently hydrolyzed cEs (cE2 > cE1 > cE3) into corresponding fEs, transiently increased estrogenic activity and potential toxicity, and rapidly degraded fEs (fE2, fE1 > fE3), thus reducing the estrogenic activity in manure. Unlike aerobic processing, anaerobic processing stabilized and

Manure additions to cropland can reduce total P losses in runoff on well-drained soils due to increased infiltration and reduced soil erosion. Surface residue management in subsequent years may influence the long-term risk of P losses as the manure-supplied organic matter decomposes. The effects of manure history and long-term (8-yr) tillage [chisel plow (CP) and no-till (NT)] on P levels in runoff in continuous corn (Zea mays L.) were investigated on well-drained silt loam soils of southern and southwestern Wisconsin. Soil P levels (0-15 cm) increased with the frequency of manure applications and P stratification was greater near the surface (0-5 cm) in NT than CP. In CP, soil test P level was linearly related to dissolved P (24-105 g ha?1) and bioavailable P (64-272 g ha?1) loads in runoff, but not total P (653-1893 g ha?1). In NT, P loads were reduced by an average of 57% for dissolved P, 70% for bioavailable P, and 91% for total P compared with CP. This reduction was due to lower sediment ...
The aim of this study was to assess the prevalence of ESBL-producing E. coli in agricultural fields of Gorgan district, Golestan province. Soil samples were collected from 20 agricultural fields, half of them treated with chemical fertilizers and the rest with bovine manure. Two samples, from surface and a depth of 15cm, were taken. After enrichment and culture onto MacConkey agar, Pink colored colonies were examined for Escherichia coli. The cefotaxime resistant E. coli were examined by phenotypic confirmatory tests. Then, antibiotic susceptibility of the confirmed ESBL-producing E. coli strains was determined. The results of this study showed that the prevalence of E. coli in the manure-amended soils were higher than the soils enriched with chemical fertilizers. Moreover, E. coli strains in the depth samples were more than the surface samples. About %53.1 of the strains isolated from the manure-amended soils were resistant to Cefotaxime and the %43 of them were positive for ESBL. Meanwhile, %33.3 of
Livestock manure applications on fields can be a source of contamination in water resources, including groundwater. Although fecal indicators like Escherichia coli have often been detected in tile drainage systems, few studies have monitored groundwater at depth following manure treatments, especially at sites with a deep, heterogeneous vadose zone. Our hypothesis was that microbial transport through a thick vadose zone would be limited or non-existent due to attenuation processes, and subsurface thickness and heterogeneity. This study tested this hypothesis by monitoring E. coli concentrations beneath a 12-meter thick vadose zone of coarse, heterogeneous glacial sediments, following surface application of liquid swine manure. E. coli were detected on all 23 sample dates over the five month period (04/04/2012- 13/08/2012), with particularly elevated concentrations one week after application and lasting for five weeks. Variable low-level concentrations both before and after the elevated period ...

In field campaign FC1 (2 days after manure application on pasture "East"), both ER-CALUX and YES recorded a slight increase in EEQ at "Shaft", close to the LOD of both assays. At "Outlet", where the drainage waters of the whole system merge, the EEQ values were below the level of quantification (ER-CALUX) and below the level of detection (YES). Outflow at "Shaft" was only moderately increased by the 4.6 mm of rain. Soil moisture tension in the lower part of the soil remained high and did not drop, as it would be expected during an infiltration event (Fig. 3). This indicates that the upper soil layer was able to absorb the rainwater and no significant washout of manure constituents took place.. Field campaign FC2 (14 days after manure application on pasture "East") was conducted on a sunny day between 11:30 and 15:30. A rain event had been forecasted for this afternoon, and when it did not occur, we intended to use the FC as a dry weather reference. In the 12 days before FC2, a total of 67.9 mm ...

Animal waste is considered to be a significant source of potentially hazardous and odorous emissions. Emissions associated with swine manure consist of gases such as ammonia (NH3), hydrogen sulfide (H2S), greenhouse gases (GHGs) and volatile organic compounds (VOCs). Comprehensive, effective, practical, and inexpensive treatment is in high demand. Biochar is mainly known for being soil amendment, has been used for remediation of heavy metals from wastewater, and as an adsorbent for gases due to its porosity. Thus, it is proposed that biochar could be used as an effective and practical treatment for gaseous emissions from stored manure. Data is needed on the performance of biochar to mitigate gaseous emissions from swine manure including simple floatation tests. The hypothesis of mechanism how biochar mitigates emissions from swine manure is that it can influence manure pH, and by that inhibit gaseous emissions transfer from liquid to air, by, for instance, preventing NH4+ transformation to gaseous NH3.
Bovine manures have a really low nutrient profile, something like 0.6-0.2-0.5. (highly variable by season, locale, herd type, and feedstock) of immediately available nutrients. In beds where theres room to add a lot, and where the slow release of previously unavailable nutrients happens due to plenty of soil microorganisms thats okay. Beds allow for the high salts present in many bovine manures to be leached and help buffer variables in nutrient profiles. Manures are also great for soil conditioning, increasing soil organic matter and therefore cation exchange sites and humic acids. However, I wouldnt use them in seasonal vegetable containers, especially sub-irrigated planters where sodium build up would be a problem, and where fertilizers with more immediate nutrient availability are needed due to the shorter growing cycles of most container grown vegetables. You also would want much higher nutrient density in situations where you have a finite amount of growing medium. One would expect ...
ROCK SPRINGS, Pa. - With water quality in the Chesapeake Bay suffering from excess nutrients and fish populations in rivers such as the Susquehanna experiencing gender skewing and other reproductive abnormalities, understanding how to minimize runoff of both nutrients and endocrine-disrupting compounds from farm fields after manure applications is a critical objective for agriculture.. A new study by researchers in Penn States College of Agricultural Sciences shows that applying manure to crop fields by means of shallow disk injection into the soil rather than traditional surface broadcast significantly reduces estrogens in surface runoff. This finding suggests that manure-application methods can be used to control the mobilization potential of estrogens and points to opportunities for protecting downstream water quality.. The research, published this month in Agriculture, Ecosystems and Environment, also investigated how manure-application methods affected runoff of total dissolved phosphorus ...
Anaerobic digestion is one of the best available technologies for food waste (FW) and pig manure (PM) management by producing methane-rich biogas. However, mono digestion of FW or PM is easily inhibited by high volatile fatty acid (VFA) or ammonia. Co-digestion of FW and PM can provide an effective solution to address these issues due to the buffering interactions between the VFA and ammonia. Compared with wet digestion, dry digestion can reduce the digester volume significantly, thereby decreasing initial capital expenditure and the energy consumption required for heating. In this research, batch dry co-digestion of FW and PM was conducted in laboratory-scale digesters at the total solid (TS) content of 20%. The research objectives were to assess (1) the feasibility and optimal operation conditions of dry co-digestion systems; (2) methane production kinetics and the inhibition mechanisms; (3) the biosafety of digestate, i.e. the inactivation of enteric indicator bacteria, including total ...

The great horse manure crisis of 1894 is a notion in urban planning which stated that the greatest challenge of further urban development was a difficulty of removing horse manure from the streets. More broadly, it is an analogy for supposedly insuperable extrapolated problems being rendered moot by the introduction of new technologies. The phrase originates from a 2004 article by Stephen Davies entitled "The Great Horse-Manure Crisis of 1894".[1][2] The supposed problem of excessive horse-manure collecting in the streets was solved by the proliferation of cars which replaced horses as the means of transportation in big cities. The term great horse manure crisis of 1894 is often used to denote a problem which seems to be impossible to solve because it is being looked at from the wrong direction.[3][4] The name refers to a supposed 1894 publication in The Times, which said "In 50 years, every street in London will be buried under nine feet of manure".[3] The reasoning was that more horses are ...

Zero liquid discharge is increasing adopted as an objective for waste treatment process. The objective of this study was to increase the feed total solids (TS) and the organic loading rate (OLR) fed to a novel psychrophilic (20 °C) dry anaerobic digestion (PDAD). Duplicate laboratory-scale bioreactors were fed cow feces and wheat straw (35% TS in feed) at OLR of 6.0 g TCOD kg-1 inoculum d-1 during long-term operation (147 days consisting of 7 successive cycles). An overall average specific methane yield (SMY) of 151.8±7.9 N L CH4 kg-1 VS fed with an averaged volatile solids removal of 42.4±4.3% were obtained at a volatile solids-based inoculum-to-substrate ratio (ISR) of 2.13±0.2. The operation was stable as indicated by biogas and VFAs profiles and the results were reproducible in successive cycles; a maximum SMY of 163.3±5.7 N L CH4 kg-1 VS fed was obtained. Hydrolysis was the reaction limiting step. High rate PDAD of 35% TS dairy manure is possible in sequential batch reactor within 21 ...
Six ponds of 25 M2 each provided with plastic canopies for temperature control, were used for stocking the fish. In each pond the tilapia O. mossambicus (Zululand strain) were stocked at a density of 40,000/ha. The mean individual mass of fish at stocking was 38.5 g. All Fish in each pond were individually weighed before stocking. Pig manure was applied to each pond for six days per week at 2.5 percent (dry mass of the total live biomass of the fish in the ponds. Mass adjustment of the pig manure dosage programme for the different ponds was made fortnightly, based on fish mass assessment using 20 -30 percent subsamples. Two sets of 3 ponds each were investigated. In the first three ponds, manure from EM-A treated pigs were used. The second group of ponds received manure from the untreated (control) pigs. In addition to pig manure, all fish ponds received a 30 percent protein formulated fish pellet daily for 6 days/week at 4 percent of the estimated fish biomass per pond. Due to the build up of ...
Canadian grain and oilseed growers are cutting their production costs by using swine, and other livestock manure, to displace some of the commercial fertilizer normally applied to boost crop quality and yield.
Composting is an effective waste management technology for converting animal wastes into valuable organic fertilizer. However, air emissions from composting, especially ammonia (NH3) emission, reduces the nitrogen fertilizer value of the compost and greatly impacts the environment. Ammonia emission from commercial composting facilities is not well understood and is limiting mitigation or recovery of NH3 emission from these facilities. The goal of this study was to determine the NH3 emission from a poultry manure compost facility and its temporal variations for development of mitigation strategies. A commercial composting facility was chosen for this study. Manure was supplied from four adjacent manure-belt layer barns. The composting building was tunnel ventilated by four 122-cm exhaust fans. Ammonia concentration at the building inlet and the fan exhausts was monitored quasi-continuously for one month in each of the four seasons using a MSA photoacoustic NH3 analyzer. Air temperature and humidity at
An anaerobic lagoon or manure lagoon is a man-made outdoor earthen basin filled with animal waste that undergoes anaerobic respiration as part of a system designed to manage and treat refuse created by Concentrated Animal Feeding Operations (CAFOs). Anaerobic lagoons are created from a manure slurry, which is washed out from underneath the animal pens and then piped into the lagoon. Sometimes the slurry is placed in an intermediary holding tank under or next to the barns before it is deposited in a lagoon. Once in the lagoon, the manure settles into two layers: solid, or sludge, layer and the liquid layer. The manure then undergoes the process of anaerobic respiration, whereby the volatile organic compounds are converted into carbon dioxide and methane. Anaerobic lagoons are usually used to pretreat high strength industrial wastewaters, and municipal wastewaters. This allows for preliminary sedimentation of suspended solids as a pretreatment process. Anaerobic lagoons have been shown to harbor ...

We also remain on track to launch our commercial program for the sterilization of leachates in landfills with our Italian partners in early 2018 ...
It has been demonstrated that hydrothermal liquefaction (HTL) could be an efficient technology that can not only reduce COD and pollutants in the bio-wastes but also generate valuable renewable bio-crude oil from many biomass sources. Previously, swine manure has been successfully converted into bio-crude oil through HTL with yield as high as 70% of the volatile solids at the University of Illinois at Urbana-Champaign. To further understand the fundamental mechanisms of HTL and to provide information for further developments of this technology, experiments with both model compounds and typical biomass (e.g. swine manure) as feedstock were conducted, the product distribution and the properties were analyzed. Some possible reaction pathways of specific compounds were proposed. HTL tests were conducted for swine manure collected from nursery, grower-finisher and sow pigs. The testing conditions were: reaction temperature 305oC, initial solid content 20% wt, retention time 30 min, initial N2 gas ...
Thinking of applying manure this fall? There are some unique challenges this year, courtesy Mother Natures stinginess with rainfall through this last growing season. The extended period of dry weather has caused low water flow in many Iowa streams, says Angela Rieck-Hinz, coordinator of the Iowa Manure Management Action Group and Iowa Satate University Extension program specialist. Low flow coupled with high temperatures has put a strain on aquatic life in many Iowa streams and can cause the streams to be highly vulnerable to any nutrients that may reach it.

A gravity settling basin may be less costly while removing 50 percent or more of the solids from liquid manure. Solids can be settled and filtered by a shallow basin (2 to 3 feet deep) with concrete floors and walls and a porous dam or perforated pipe outlet. Basins should allow access by a front-end loader to remove solids every 1 to 2 months.. An alternative is an earthen settling basin for 6 to 12 months storage of solids. The basin top width should be no more than 100 feet with a length-to-width ratio near 3:1 and a liquid depth of 8 to 10 feet. The basin contents should be thoroughly agitated and removed for land spreading either by liquid manure spreader or slurry irrigation. If an earthen basin is used, the operator must make the necessary inspections discussed earlier in this chapter for anaerobic lagoons. The dam structure and waste level must be constantly monitored, and the dam structure maintained to allow visual inspection for structural deterioration.. A third alternative consists ...
by Paul Burdziakowski. Manure has a wide range of environmental and nutrient based benefits. When properly applied to soil it has the potential to make crops grow and thrive. In order for proper application to take place it is first necessary to understand something about the structural makeup and nutrient composition of manure. Manure begins as organic material that was once alive such as plant or animal tissue. Organic material remains classified as such until it is introduced to the soil where it undergoes decomposition. During decomposition organic material is converted by microorganisms into the next usable phase known as organic matter.. One person who is quite knowledgeable on the topic of organic matter is a vegetable and berry specialist at the University of Vermont Extension, Vern Grubinger. He says there are three forms of organic matter that can be found in the soil and each one is determined by the time it takes for it to completely decompose.. The first form is known as humus or ...
Manure is often viewed by many as an environmental liability. However, if manure is applied at rates equal to or less than the nitrogen (N) requirement of a crop, can manure produce environmental benefits over commercial fertilizer?
Pros and Cons of house flies for animal feed production. An advantage of HF is that females lay a large amount of eggs; approximately 500 eggs in the wild and more than 2000 eggs in the controlled environment of the lab. Accompanied by the completion of their larval stage within four days under optimal conditions, HFs seem to be suited for a rapid production of larvae for animal feed production. Similar to BSF, the pre-pupa larval stage is commonly utilised for animal feed production.. HFL can grow on a wide range of organic substrates, including nutrient-poor cow manure, suggesting that they are relatively frugal. This characteristic could be used to turn organic wastes or low-quality substrates into high quality protein for animal feed, as well as nutrient rich fertilisers. HFL also require only small amounts of substrate for feeding, partly due to their fast life cycle. Around 1500 larvae have been reared on around 450 g of fresh manure.. In many studies, animal manure has been used as ...
Antibiotic resistance is a growing human health threat, making infections more difficult to treat and increasing fatalities from and cost of treatment of associated diseases. The rise of multidrug resistant pathogens threatens a return to the pre-antibiotic era where even the most common infections may be impossible to treat. It is estimated that the majority of global antibiotic use, and use in the U.S., is dedicated towards livestock, where they are used to promote growth, treat, or prevent disease. Given that exposure to antibiotics selects for antibiotic resistant bacteria (ARBs) and can stimulate the horizontal transfer of their associated antibiotic resistance genes (ARGs), it is important to examine livestock operations as a reservoir of resistance. Correspondingly, there is growing interest in identifying how agricultural practices can limit the potential for spread of antibiotic resistance through the �[BULLET]farm to fork continuum,�[BULLET] starting with antibiotic use practices, ...
An effective and practical tool for estimating ammonia (NH3) nitrogen emission from animal feeding operations is needed to enable the animal producers to report ammonia emission required by the Emergency Planning and Community Right-to-Know Act (EPCRA) of the Clean Air Act (CAA). The tool is also needed by producers to evaluate and adopt various nitrogen conservation management practices or technologies. This fact sheet introduces an innovative mass-balance modeling tool for estimation of ammonia emission from manure-belt poultry houses.. The alternative mass-balance method can be used to estimate ammonia emission factors from manure-belt poultry layer houses. Three composite manure samples from three manure belts can be sampled during a manure removal event. Nitrogen and ash contents of feed can be obtained directly from producer formula or feed samples from feed bins. The nitrogen and ash content of eggs can be sampled as little as once or twice due to the low variance in N and ash values. ...
Industrialized small-scale pig farming has been rapidly developed in developing regions such as China and Southeast Asia, but the environmental problems accompanying pig farming have not been fully recognized. This study investigated 168 small-scale pig farms and 29 example pig farms in Yujiang County of China to examine current and potential impacts of pig wastes on soil, water and crop qualities in the hilly red soil region, China. The results indicated that the small-scale pig farms produced considerable annual yields of wastes, with medians of 216, 333 and 773 ton yr-1 per pig farm for manure, urine and washing wastewater, respectively, which has had significant impact on surface water quality ...
Luoma Egg Ranch, an egg producer near Finlayson, Minn., was fined $95,000 by state pollution regulators for violations stemming from chicken manure spills.. Luoma failed to report and attempted to cover up the liquid manure discharges from its egg-laying operation, the Minnesota Pollution Control Agency said Tuesday. The company also improperly disposed of dead chickens, another violation.. The $95,000 fine is one of the largest levied by the pollution agency in the past two years. Luoma also must take corrective actions to address the violations.. Luoma, which is located about 60 miles southwest of Duluth, declined to make someone available for comment.. Luoma failed to leave a required 1-foot clearance at the top of its manure storage areas. That led to discharges of excrement, wastewater and waste eggs into ditches and streams, and eventually into Medicine Creek. The discharges occurred in the summer and fall last year..

Current manure management schemes have been largely prompted by national legislation to reduce the overall nitrogen and phosphorus burden on the land. They have primarily focused on recycling the nutrients contained in manure by processing it to extend its range of applications and reduce the need for other more expensive types of chemical fertiliser.. The main approach to date has been to reduce volume and liquid content of the manure in order to produce a more marketable fertiliser, often in a granulate form. Where suitably processed manure cannot be used locally, the objective has been to make it economically viable to transport it to mineral-deficient areas for use in other agricultural or horticultural applications.. Specific processing techniques have included accumulating the manures nutrients in a specific fraction, via separation or incineration, or concentrating the phosphorus and other non-volatile compounds through evaporation or drying.. Research continues into viable nitrate and ...

William D McBride and Nigel Key. AER-818, February 01, 2003 Rapid change in the size and ownership structure of U.S. hog production has created new and varied challenges for the industry. This report describes an industry becoming increasingly concentrated among fewer and larger farms, and becoming more economically efficient. These changes have not come without problems. The increasing market control and power concentrated among packers and large hog operations, and the manure management problem posed by an increasing concentration of hog manure on fewer operations, are paramount concerns. Addressing these concerns through regulations would likely impose economic costs that could be passed on to consumers. In addition, the relative mobility of the hog industry means that regulations could result in significant changes in the location of hog production facilities, with ripple effects in local economies. Balancing environmental and economic interests will challenge policymakers dealing with the ...
Applications of liquid manures have the potential to provide nitrogen (N) that can be counted toward meeting the needs of the corn crop.
Carbon dioxide (CO2) and nitrous oxide (N2O) emissions from feed production, processing and transport. Carbon dioxide emissions originate from the expansion of feed crops and pasture into natural habitats, which causes the oxidation of C in soil and vegetation. They also originate from the use of fossil fuel to manufacture fertilizer, and process and transport feed. The emissions of N2O come from the use of fertilizers (organic or synthetic) for feed production and from the direct deposition of manure on pasture or during the management and application of manure on crop fields. Direct or indirect N2O emissions can vary greatly according to temperature and humidity at the time of application and their quantification is thus subject to high uncertainty. ...

Animal activities and management create areas in pastures prone to phosphorus loss.. Animals tend to congregate near water sources, shade trees and winter feeding areas. Consequently, these areas tend to have higher soil test phosphorus levels and more manure on the soil surface than other parts of the pasture. Maintain setbacks between these areas and water resources. Consider shifting winter feeding areas over time to distribute the nutrient benefits of these areas.. Manure on the surface of a pasture in winter and spring contains significant amounts of soluble phosphorus during a time when runoff is likely. Place animals in pastures where runoff is unlikely to reach sensitive waters during late winter and spring.. Keep animals out of steams and ponds. A single defecation by a cow in a stream can equal the phosphorus loss from a one-acre field during an entire year. Overgrazing along streams can also lead to excessive erosion initiated by hoof damage to stream banks. ...

Management of soil fertility has been the preoccupation of farmers for thousands of years. Egyptians, Romans, Babylonians, and early Germans all are recorded as using minerals and or manure to enhance the productivity of their farms.[1] The modern science of plant nutrition started in the 19th century and the work of German chemist Justus von Liebig, among others. John Bennet Lawes, an English entrepreneur, began to experiment on the effects of various manures on plants growing in pots in 1837, and a year or two later the experiments were extended to crops in the field. One immediate consequence was that in 1842 he patented a manure formed by treating phosphates with sulfuric acid, and thus was the first to create the artificial manure industry. In the succeeding year he enlisted the services of Joseph Henry Gilbert, with whom he carried on for more than half a century on experiments in raising crops at the Institute of Arable Crops Research.[103]. The Birkeland-Eyde process was one of the ...
The index can be used to predict the risk of phosphorus runoff from pastures fertilized with animal manure or commercial fertilizers, according to Moore. Poultry litter, a mixture of chicken manure, feathers, spilled food and bedding material, is an inexpensive and popular fertilizer for crop land because the manure contains nitrogen and phosphorus, two important fertilizer ingredients ...

Methane is a potent greenhouse gas but estimating how much ruminating animals produce has not been easy. Now scientists have found a correlation between levels of a compound in manure and the amount of methane released by the animal. Living on Earths Anne-Marie Singh brings us this science note.
Microbiological quality of surface waters can be affected by microbial load in runoff from grazing lands. This effect, with other factors, depends on the survival of microorganisms in animal waste deposited on pastures. Since temperature is a leading environmental parameter affecting survival, it indirectly impacts water microbial quality. The Q10 model is widely used to predict the effect of temperature on rates of biological processes, including survival. Objectives of this work were to (i) evaluate the applicability of the Q10 model to Escherichia coli inactivation in bovine manure deposited on grazing land (i.e., cowpats) and (ii) identify explanatory variables for the previously reported E. coli survival dynamics in cowpats. Data utilized in this study include published results on E. coli concentrations in natural and repacked cowpats from research conducted the U.S. (Virginia and Maryland), New Zealand, and the United Kingdom. Inspection of the datasets led to conceptualizing E. coli ...

Organic contaminants in sewage biosolids and in manure and the nutrient circular economy Europe today spreads around half of sewage sludge, after appropriate treatment, and nearly all animal manures, back to land. Where managed in response to crop nutrient needs, this ensures recycling of nutrients and micro-nutrients, and return of organic carbon to soil.. However, this recycling of organic wastes (sewage biosolids, manures, …) back to agricultural soil is under pressure because of real or perceived concerns about organic contaminants (pharmaceuticals, organic chemicals …) and their possible impacts on crops, human health, soils and the environment.. Maintaining this current recycling route is a priority for closing the loop for phosphorus and other nutrients, but safety for health, soil, crops and the environment must be ensured.. ...
Putting A Positive Spin On Manure. One man s trash the manure produced at Tinedale Farms in Wrightstown, Wisconsin can be another man s treasure electricity and fertilizer generated from that manure. In short, that was the story shared at a media conference held at the dairy in August..

11 December 2018 by Sarah McDaid. A new online calculator and guidance has been developed to help farmers and others to design woodlands to capture airborne ammonia, and so reduce air pollution.. Scientists from the Centre for Ecology & Hydrology (CEH) worked with Forest Research to develop the free online tool and guidance for users, as part of research funded by the Scottish Environment Protection Agency.. Agriculture is the main source of ammonia emissions in the UK, with the majority coming from animal manure and fertilisers. Ammonia can lead to excess reactive nitrogen levels in sensitive habitats, causing a decline in the biodiversity of lichens, mosses and other flora. It can also lead to acidification of soils, and combines with other pollutants to produce particulate matter pollution, which is harmful to human health.. By following the advice in the guidance, farmers, regulators and planning authorities can optimise tree planting to recapture ammonia around animal housing, which is a ...

SW 5512Y is a high yielding medium recovery type suited for hay and haylage production where moderate speed of regrowth initiation is desired after cutting. As a lodging tolerant variety, SW5512Y is especially well-suited to growing situations that may lead to lodging. Compared to other varieties, SW5512Y can exhibit reduced lodging in situations of heavy manure application, irrigation from overhead sprinklers, or rain that leads to harvest delays and increased lodging potential, especially when accompanied by wind.. The first cut is the heaviest cutting of the year, and most susceptible to lodging. The lodging tolerant characteristic of SW5512Y helps maintain yield of the heavy first cut, and can help maintain forage quality of second and later cuttings through the reduction of long trailing uncut stems that often remain after cutting a lodged crop. Such uncut stems become less digestible, leading to forage quality reduction if harvested in subsequent cuttings. ...
