Global environmental impacts of agricultural expansion: the need for sustainable and efficient practices. (1/404)

The recent intensification of agriculture, and the prospects of future intensification, will have major detrimental impacts on the nonagricultural terrestrial and aquatic ecosystems of the world. The doubling of agricultural food production during the past 35 years was associated with a 6.87-fold increase in nitrogen fertilization, a 3.48-fold increase in phosphorus fertilization, a 1.68-fold increase in the amount of irrigated cropland, and a 1.1-fold increase in land in cultivation. Based on a simple linear extension of past trends, the anticipated next doubling of global food production would be associated with approximately 3-fold increases in nitrogen and phosphorus fertilization rates, a doubling of the irrigated land area, and an 18% increase in cropland. These projected changes would have dramatic impacts on the diversity, composition, and functioning of the remaining natural ecosystems of the world, and on their ability to provide society with a variety of essential ecosystem services. The largest impacts would be on freshwater and marine ecosystems, which would be greatly eutrophied by high rates of nitrogen and phosphorus release from agricultural fields. Aquatic nutrient eutrophication can lead to loss of biodiversity, outbreaks of nuisance species, shifts in the structure of food chains, and impairment of fisheries. Because of aerial redistribution of various forms of nitrogen, agricultural intensification also would eutrophy many natural terrestrial ecosystems and contribute to atmospheric accumulation of greenhouse gases. These detrimental environmental impacts of agriculture can be minimized only if there is much more efficient use and recycling of nitrogen and phosphorus in agroecosystems.  (+info)

Nitrogen management and the future of food: lessons from the management of energy and carbon. (2/404)

The food system dominates anthropogenic disruption of the nitrogen cycle by generating excess fixed nitrogen. Excess fixed nitrogen, in various guises, augments the greenhouse effect, diminishes stratospheric ozone, promotes smog, contaminates drinking water, acidifies rain, eutrophies bays and estuaries, and stresses ecosystems. Yet, to date, regulatory efforts to limit these disruptions largely ignore the food system. There are many parallels between food and energy. Food is to nitrogen as energy is to carbon. Nitrogen fertilizer is analogous to fossil fuel. Organic agriculture and agricultural biotechnology play roles analogous to renewable energy and nuclear power in political discourse. Nutrition research resembles energy end-use analysis. Meat is the electricity of food. As the agriculture and food system evolves to contain its impacts on the nitrogen cycle, several lessons can be extracted from energy and carbon: (i) set the goal of ecosystem stabilization; (ii) search the entire production and consumption system (grain, livestock, food distribution, and diet) for opportunities to improve efficiency; (iii) implement cap-and-trade systems for fixed nitrogen; (iv) expand research at the intersection of agriculture and ecology, and (v) focus on the food choices of the prosperous. There are important nitrogen-carbon links. The global increase in fixed nitrogen may be fertilizing the Earth, transferring significant amounts of carbon from the atmosphere to the biosphere, and mitigating global warming. A modern biofuels industry someday may produce biofuels from crop residues or dedicated energy crops, reducing the rate of fossil fuel use, while losses of nitrogen and other nutrients are minimized.  (+info)

Use of molecular and isotopic techniques to monitor the response of autotrophic ammonia-oxidizing populations of the beta subdivision of the class proteobacteria in arable soils to nitrogen fertilizer. (3/404)

This study examined the effects of NH(4)NO(3) fertilizer on the size and activity of nitrifying, autotrophic, ammonia-oxidizing populations of the beta subdivision of the class Proteobacteria in arable soils. Plots under different long-term fertilizer regimes were sampled before and after NH(4)NO(3) additions, and the rates of nitrification were determined by (15)N isotopic pool dilution assays. Ammonia-oxidizing populations in the plots were quantified by competitive PCR assays based on the amoA and ribosomal 16S genes. Prior to fertilizer addition, ammonium concentrations and nitrification rates in the plots were comparatively low; ammonia-oxidizing populations were present at 10(4) to 10(5) gene copies g of soil(-1). Three days after the application of fertilizer, nitrification rates had risen considerably but the size of the ammonia-oxidizing population was unchanged. Six weeks after fertilizer treatment, ammonium concentrations and nitrification rates had fallen while the ammonia-oxidizing populations in plots receiving fertilizer had increased. The rapidity of the rise in nitrification rates observed after 3 days suggests that it results from phenotypic changes in the ammonia-oxidizing bacterial population. Associated increases in population sizes were only observed after 6 weeks and did not correlate directly with nitrifying activity. Phylogenetic analyses of PCR products from one of the plots revealed a population dominated by Nitrosospira-type organisms, similar to those prevalent in other soils.  (+info)

Nitrogen pollution: an assessment of its threat to amphibian survival. (4/404)

The potential for nitrate to affect amphibian survival was evaluated by examining the areas in North America where concentrations of nitrate in water occur above amphibian toxicity thresholds. Nitrogen pollution from anthropogenic sources enters bodies of water through agricultural runoff or percolation associated with nitrogen fertilization, livestock, precipitation, and effluents from industrial and human wastes. Environmental concentrations of nitrate in watersheds throughout North America range from < 1 to > 100 mg/L. Of the 8,545 water quality samples collected from states and provinces bordering the Great Lakes, 19.8% contained nitrate concentrations exceeding those which can cause sublethal effects in amphibians. In the laboratory lethal and sublethal effects in amphibians are detected at nitrate concentrations between 2.5 and 100 mg/L. Furthermore, amphibian prey such as insects and predators of amphibians such as fish are also sensitive to these elevated levels of nitrate. From this we conclude that nitrate concentrations in some watersheds in North America are high enough to cause death and developmental anomalies in amphibians and impact other animals in aquatic ecosystems. In some situations, the use of vegetated buffer strips adjacent to water courses can reduce nitrogen contamination of surface waters. Ultimately, there is a need to reduce runoff, sewage effluent discharge, and the use of fertilizers, and to establish and enforce water quality guidelines for nitrate for the protection of aquatic organisms.  (+info)

Examination of slurry from cattle for pathogenic bacteria. (5/404)

One hundred and eighty-seven samples of slurry from cattle were examined forthe presence of salmonellas, pathogenic leptospires and brucellas. Small numbers of salmonellas, generally less than 1/g., were isolated from 20 samples (11%). These were S. dublin (12), S. typhimurium (4), S. indiana (1), S. bredeney (1), S. cerro (1) and S. unnamed 4, 12:d:-(1). Leptospires were isolated from 56 samples (30%) but none was pathogenic for hamsters. No brucellas were isolated. The results of this survey are discussed in relation to the epidemiology of salmonellosis.  (+info)

The effect of storage in slurry on the virulence of Salmonella dublin. (6/404)

The mouse was used as a model to determine whether storage of Salmonella dublin in slurry and in broth reduces the virulence of the organism. No reduction in virulence of S. dublin stored in slurry for 36 days or in maintenance broth for 70 days was observed. The disease hazard involved in pasture-spreading of slurry contaminated with salmonellas is related to factors other than virulence.  (+info)

Farming from a new perspective: remote sensing comes down to earth. (7/404)

Farmers strive to increase the yield of their fields by adding nutrients and water to the land, and using pesticides to control insects and disease. In addition to bountiful harvests, the results of their endeavors may include elevated amounts of fertilizers in surface waters and aquifers and potential risk to themselves and their neighbors from exposure to pesticides. Precision agriculture is the use of modern information technologies such as geographic information systems, the global positioning system, and remote sensing from the air to reduce the environmental effects of these chemicals while enhancing the productivity of farming. By combining crop yield maps with soil survey maps and remote sensing output, farmers can identify areas that need more or less fertilizer, water, or pesticide.  (+info)

Survival of coliform bacteria in sewage sludge applied to a forest clearcut and potential movement into groundwater. (8/404)

Anaerobically digested dewatered sludge (10 to 15 cm thick) was applied to a forest clearcut as a fertilizer source in northwest Washington on gravelly glacial outwash soil. This sludge is not microbiologically sterile and may contain pathogenic organisms. Fecal coliform bacterial counts in sludge applied in summer (July) fell from 1.08 X 10(5) to 358/g in 204 days and to 0/g in 267 days. Dieoff appeared more rapid in winter (January)-applied sludge, when colnts fell from 1.2 X 10(5) to 20/g in 162 days. Initial death rates were related to sludge temperature, moisture, pH, physical composition, and microbial competition. Aftergrowth of fecal coliforms occurred in warm summer and fall months, but counts were of similar magnitude to background levels in forest soils, where a maximum count of 54/g was recorded. Total coliform counts in fresh sludge ranged from 1.4 X 10(4) to 1.9 X 10(6)/g. Numbers stabilized at 10(3) to 10(4)/g in spring, fall, and summer, with lower numbers in winter. Both total and fecal bacteria moved from the sludge to the soil beneath, but few penetrated past the first 5 cm. The soil acts as an effective biological filter. Few fecal coliform bacteria were recorded in the groundwater, generally being less than 5/100 ml and mostly 0/100 ml. A maximum count of 52/100 ml was recorded. Groundwater contamination from vertical movement of potential pathogens appears unlikely, but hazards from surface runoff and direct handling in the first year may arise.  (+info)

Present research was carried out during the year 2014-2015 at the National Agricultural Research and Extension Institute (NAREI) to determine the effect of vermicompost and other fertilizers on the growth and productivity of pepper plants (Capsicum chinense). Plants were treated with five different treatments, namely T1 (Promix), T2 (vermicompost), T3 (189), T4 (189 + vermicompost), and lastly, control which had no fertilizers. T1, T3, and T4 were inorganic fertilizers, and T2 was organic. Results obtained showed that T3 (chemical fertilizer) has a significant effect on the growth of pepper plants producing plants with better plant height, number of leaves, number of branches, stem diameter, higher fruit yield, fruit weight and fruit diameter. Plants treated with this treatment also had higher fruit yield, fruit weight, and fruit diameter. Mineral nutrients were highest in plants treated with inorganic fertilizers as compared to the organic fertilizer. Maximum chlorophyll level was present in plants

There are positives and negatives to both. Organic fertilizers are made from the remains of once living things, therefore they contain carbon. Inorganic fertilizers are man-made from mineral salts, and contain no carbon. (The definition of organic varies widely, but it usually contains carbon.) Miracle Gro is considered inorganic. At the smallest level that plant roots are taking up nutrients, there is no difference to the plant. However, organic fertilizers (such as fish emulsion, alfalfa meal, blood meal, bone meal) provide long-term benefits to the soil, by giving soil microorganisms and earthworms food. Organic matter also improves the structure and workability of soil over time. Organic fertilizers are less likely to burn plants because they have low concentrations of nutrients (e.g., 5-3-1). Organics are slower working, but remain available to the plants longer. They are usually more expensive ...

People are paying more for food, clothing and paper with the belief that these products are better for the environment and their health. The use of organic fertilizer over chemical fertilizer has created much debate and heated arguments. When gardeners talk about fertilizer they use terms like inorganic, manufactured, synthetic, manure, natural, compost, crap and artificial. Since many times it is hard to know the amount of nutrients in organic fertilizers many times they are sold as soil conditioners. Examples of organic fertilizers are plant compost, animal crap or manure, bone meal, and mushroom compost. Since the nutrients are released when the manure or compost is broken down, there isnt much control of getting the nutrients to the plants when they need it. The concerns of chemical fertilizers are they are produced from nonrenewable sources including fossil fuels and it is easy to over fertilize with them. The bottom line is your plants will not know if they get their nutrients from an
ABSTRACT Human food chain toxicity, soil fertility and agricultural output have been shown to be influenced by application of various types of fertilizers. This research studied the influence of multiple fertilizer application on soil quality and plant heavy metal accumulation, proximate and phytochemical compositions. The different fertilizer samples used were NlSPlSKlS (CFI), N20PIOKIO (CF2), N27P13PI3 (CF3), pig manure (AMI) and chicken manure (AM2). Plant species used were Telfairia occidental is and Talinum triangulare. The experiment had four treatments and each treatment had 0.0, 2.0 and 4.0glkg soil. The seeds of the vegetables were planted and allowed to grow for a period of 12 weeks. The first sets of the experimental pots were left for a latent period of 12 weeks after the first harvest for second fertilizer application. The heavy metal composition of the different fertilizers and control soil as well as the plant species were studied using Atomic Absorption Spectrophotometry (AAS). ...

Soil in Florida is very sandy and low in minerals. Growing anything in such soil can be a real challenge, especially for novice gardeners.. Fortunately, there is an organic nursery in my community that has provided me with excellent advice over the years on how to overcome the difficulties of growing edible plants in sandy soil without resorting to chemical fertilizers.. While Ive tried a number of different organic fertilizers in the past, my favorite continues to be liquid fish and seaweed fertilizer concentrate. A gallon of this stuff will last you forever - unless you leave it outside which guarantees that it will be ripped open and destroyed by marauding raccoons!. Raccoons seem to just love anything that smells fishy!. The fish and seaweed fertilizer I use has a 2-3-1 ratio which indicates the percentage of nitrogen, phosphorus, and potassium by weight. While these numbers may be important for chemical fertilizers, I dont think they apply very well to organic fish/seaweed fertilizers ...

Continuous and rotational grazing showed no effects on pasture responses to fertiliser. Mean annual pasture dry matter (DM) production ranged from 11,275 to 14,155 kg DM ha−1 on Easy, and 6413 to 7480 kg DM ha−1 on Steep slopes through the range of 10-100 kg ha−1 yr−1 of phosphate (P) fertiliser rates. Initial fertiliser effects on Olsen P tests were in the 0-3 cm depth only, and in the 7-15 cm soil depth only in the 100 kg ha−1 yr−1 treatment by year 4. Near maximum (97%) annual production, derived from relative yield analysis, was obtained at 0-7 cm depth soil tests of 30 on Easy slopes and at 12 on Steep slopes.. Results from this trial are directly relevant to the variable fertiliser rate aerial application technology currently being developed.. ...
In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included nitrogen fertilizer at three levels: 69 (N1), 138 (N2) and 205 (N3) kg N ha-1 and two sorghum cultivars: Pegah and KFS2. The results showed that nitrogen fertilizer enhanced plant height, leaf area index, fresh weight, total dry weight and biological yield significantly so that these traits were higher in N3 as 5.71, 22.8, 8.13, 22.5, and 8.7% than N1, respectively. Furthermore, increasing nitrogen rate had additive effect on crop growth rate, relative growth rate, biomass duration and leaf area duration. Comparing the cultivars, it was found that, plant height, fresh weight, total dry weight and biological yield

Recent organic fertilizer treatments (cow manure, pig slurry, composts, or green manure) simultaneously increase insecticide adsorption onto soil and the insecticide soil persistence, indicating a mechanism of slow release of insecticide into soil by the organic matter. This occurred in sugar beet crops with aldicarb, thiofanox and imidacloprid; also, in leek, cauliflower and brussels sprouts crops with chlorpyrifos and chlorfenvinphos. In contrast, organic fertilizer treatments applied once or repeatedly in the past, have no significant influence on adsorption or persistence of insecticides; the same is observed for the old soil organic matter, when its soil concentrations change in limited ranges ...

Effects of six fertilizers, Ca(NO3)2, NH4Cl, NH4NO3,CO(NH2)2, KH2PO4 and KCl, on the isotherm adsorption of Cr(Ⅲ) on paddy soil were studied using batch equilibrium experiments. The results showed that the adsorption of Cr(Ⅲ) on paddy soil was inhibited to some extent by the addition of the six fertilizers. At the same initial concentration of Cr(Ⅲ), the adsorption ratio and distribution coefficient of Cr(Ⅲ) decreased when the fertilizers were added. The effect of potassium chloride was most obvious. When the initial Cr(Ⅲ) concentration was 1 850 mg·L-1,the adsorption ratio and distribution coefficient were decreased by 17.3% and 35.2%, respectively. According to the adsorption maxima b calculated from Langmuir equation, the inhibition capability of six fertilizers on adsorption of Cr(Ⅲ) followed the order: KCl KH2PO4 NH4Cl CO(NH2)2 NH4NO3 Ca(NO3)2. The order of the adsorption potential E0 from De Boer-Zwikker equation was as follow: KCl KH2PO4 NH4Cl CO(NH2)2 NH4NO3 Ca(NO3)2 no fertilizer.
A great deal is possible from a technological standpoint - sometimes even with less effort and expense than expected. In Olfs opinion, there are two basic problems with classic mineral fertiliser. For example, fertiliser is often not applied exactly, especially perpendicular to the driving lane. If the fertiliser applied overlaps too heavily, then for example, too much nitrogen (N) enters the soil in some areas. Grain can go into storage later if the coefficient of variation, i.e. the measure of the accuracy in lateral distribution, exceeds 30 percent. The second problem concerns the physical properties such as the particle sizes of mineral fertiliser. If it is frequently reloaded as bulk product", pressure and abrasion crush the fertiliser pellets. The fertiliser pellets become a kind of powder that is difficult to distribute. As a result, fertiliser management expert Olfs sees mineral fertiliser in big bags as more complex and expensive, but with regard to distribution accuracy considers it ...

Elevated atmospheric CO2 (eCO2) and increased nitrogen (N) fertilization significantly change the nutritional quality of plants and influence the growth and development of insects. However, little is known about plant metabolism and plant-insect interactions under eCO2 and increased N fertilization, especially C4 plants. Thus, the combined effects of eCO2 and increased N fertilization on maize-Ostrinia furnacalis interactions were tested in this study. Our data demonstrated that both eCO2 and increased N fertilization increased starch content, while increased N fertilization promoted the N content in maize. The combined effects of eCO2 and increased N fertilization did not influence the total non-structural carbohydrates (TNC):N ratio in maize. The jasmonic acid level of maize was enhanced by increased N fertilization and O. furnacalis infestation. The total phenolics content and defensive enzyme activities of maize increased under eCO2, increased N fertilization and O. furnacalis infestation.
