Accurate accounting of irrigation water use is an important part of the U.S. Geological Survey National Water-Use Information Program and the WaterSMART initiative to help maintain sustainable water resources in the Nation. Irrigation water use in the humid eastern United States is not well characterized because of inadequate reporting and wide variability associated with climate, soils, crops, and farming practices. To better understand irrigation water use in the eastern United States, two types of predictive models were developed and compared by using metered irrigation water-use data for corn, cotton, peanut, and soybean crops in Georgia and turf farms in Rhode Island. Reliable metered irrigation data were limited to these areas. The first predictive model that was developed uses logistic regression to predict the occurrence of irrigation on the basis of antecedent climate conditions. Logistic regression equations were developed for corn, cotton, peanut, and soybean crops by using weekly irrigation.

Tree growth, fruit production and population dynamics of three root-knot nematodes, Meloidogyne incognita, M. arenaria and M. javanica were evaluated during six years in a peach planting. The treatments were: 1) preplant soil fumigation with methyl bromide at 450 kg/ha + mycorrhizae at planting, 2) root-knot nematode + Dactylella oviparasitica (S isolate), 3) root-knot nematode + soil from an established peach orchard, and 4) root-knot nematode alone. These four treatments were evaluated under normal and high irrigation regimes. Methyl bromide treatment improved tree growth, fruit production, and nematode control most. D. oviparasitica did not improve growth. The high irrigation regime counteracted the detrimental effects of root-knot nematode without reducing the nematode population. After 6 years root-knot nematode numbers were declining in all treatments except those previously free of the nematode.

Impact of regulated deficit irrigation on the physiological characteristics of two rapeseed varieties as affected by different potassium rates

Due to climate changes and increased demands of different water users (agriculture, industry, domestic) water becomes scarce resources worldwide. Since irrigated agriculture is the one of the largest consumer of these resources (so called blue water footprint), irrigation management must be shifted from maximal production per crop area to maximal production per unit of water used by crops. Among the strategies for reducing water footprints, changing the full irrigation to the reduced crops water supply (deficit irrigation techniques) is one of the options. In this mini-review we present the latest advances of partial root-zone drying (PRD) applications in different agricultural plants, with the special emphases on the PRD effects on increasing WUE, yield and yield quality. We describe two PRD practical approaches (alternate and fixed), background of PRD induced increase in yield and water use efficiency and improved understanding about nutrient use efficiency. The evidence of PRD effect on the increase

The impact of water deficit on berry quality has been extensively investigated during the last decades. Nonetheless, there is a scarcity of knowledge on the performance of varieties exposed to a combination of high temperatures/water stress during the growing season and under vineyard conditions. The objective of this research was to investigate the effects of two irrigation regimes, sustained deficit irrigation (SDI, 30% ETc) and regulated deficit irrigation (RDI, 15% ETc) and of two cluster positions within the canopy (east- and west-exposed sides) on berry ripening in red Aragonez (Tempranillo) grapevines. The study was undertaken for two successive years in a commercial vineyard in South Portugal, monitoring the following parameters: pre-dawn leaf water potential, berry temperature, sugars, polyphenols, abscisic acid (ABA) and related metabolites. Additionally, expression patterns for different transcripts encoding for enzymes responsible for anthocyanin and ABA biosynthesis (VviUFGT, VvNCED1,

The model estimates supplementary irrigation water requirements to maintain optimal conditions for plant growth: for that it maintains a soil moisture level between field capacity and MAD: Management Allowed Depletion, expressed as a percentage of field capacity (e.g., 50%). If the lower MAD threshold is being reached, supplementary irrigation water is added; How much depends on irrigation technology: for each technology, a target (expressed as % of MAD (where 100% means up to field capacity, and 0 means up to MAD level, i.e., it describes an irrigation technology specific excess of water (above MAD) that can be supplied, to smooth oscillations of soil moisture or water levels in paddies) and a maximum technology specific daily application rate in mm can be specified. The defaults are 0 % (only apply up to MAD) and unlimited (whatever amount of water is required to reach the target soil water content.) The MAD level for a crop is either constant, or can optionally be specified as a time series ...

Characteristics of Groundwater Quality for Agricultural Irrigation in Plastic Film House Using Multivariate Analysis Multivariate statistical analysis;Groundwater quality;Factor analysis;Irrigation water; The main purpose of this study is to accumulate the fundamental data representing groundwater of plastic film houses by means of water quality and its multivariate statistical analysis. Groundwater samples were collected in every two years since 2000 to 2004 from total 211 sites. According to the result of water quality analysis, ground water quality was suitable for irrigation purpose averagely. Correlation analysis showed that EC was highest positively correlated with $Mg^{2+}$ to 0.810(p<0.01), 0.776(p<0.01) in April and July, respectively. $NO_3-N$ was highest positively correlated with T-N to 0.794(p<0.01) in October. This result shows that it can lead to a different result even in similar case sometimes. Four factors were extracted through factor analysis in April and July, but five factors

Heat pasteurization of root zone substrates is a common practice, but not so for irrigation water. Yet in The Netherlands, heat pasteurization is the most common water treatment system. Typical recommendations for heat pasteurization of irrigation water require that the water or nutrient solution pass through a heat exchanger and heated to 203°F (95°C) for 30 seconds, yet viruses can be inactivated at 131°F (55°C) and 158°F (70°C) for 90 and five minutes, respectively ...

The role of irrigation water in disseminating Erwinia amylovora is not fully recognized, and the survival of the bacterium in natural water has not been carefully investigated. This risk has been underestimated, since it is generally considered that E. amylovora survives only for a short period in water and its isolation from natural water samples has not been reported. The main goal of this study has been to clarify whether E. amylovora could survive under nutrient starvation conditions usually found in aquatic environments and if it is nonculturable on solid media when recovered from sterile natural water. Infectivity of E. amylovora cells in water was evaluated by using immature pear fruits. Total and viable cell counts were monitored by the Live/Dead viability kit, and culturability by plate counts on King's B medium. E. amylovora was able to survive in water from different sources showing a long persistence in irrigation water and maintaining its infectivity for green pears. However, a ...

2] Agriculture is perhaps one of the most important sectors of Californias economy and a major provider of agricultural products to the United States and the global markets. However, given the semiarid nature of Californias agricultural region and lack of sufficient precipitation, irrigation has been the main method of meeting the water demand and ensuring high crop yields. In relationship to water conservation and addressing water shortages in California, Hanson et al. [2004] studied when to irrigate and how much water to apply based on theoretical and experimental methods, in order to maintain optimum yield. They recommended that irrigation should start when the root zones available soil moisture is less than the maximum allowable depletion of a specific crop.. [3] The relationship between large-scale irrigation and climate has also received much attention, especially in recent years. Qualitatively, irrigation practices have been identified as having both direct and indirect consequences on ...

Downloadable! Over-allocation of fresh water resources to consumptive uses, coupled with recurring drought and the prospect of climate change, is compromising the stocks of natural capital in the worlds basins and reducing their ability to provide ecosystem services. To combat this, governments world wide are making significant investment in efforts to improve sharing of water between consumptive uses and the environment, with many investments centred on modernisation of inefficient irrigation delivery systems, and the purchase of water by government for environmental flows. In this study, spatial targeting was applied within a cost-benefit framework to reconfigure agricultural land use in an irrigation district to achieve a 20% reduction in agricultural water use to increase environmental flows and improve the provision of other ecosystem services. We demonstrate using spatial planning and optimisation models that a targeted land use reconfiguration policy approach could potentially increase the net

Traditionally, irrigation water is grouped into various quality classes in order to guide the user to the potential advantages as well as problems associated with its use and to achieve optimum crop production. The water quality classifications are only indicative guidelines and their application will have to be adjusted to conditions that prevail in the field. This is so because the conditions of water use in irrigation are very complex and difficult to predict. The suitability of water for irrigation will greatly depend on the climatic conditions, physical and chemical properties of the soil, the salt tolerance of the crop grown and the management practices. Thus, classification of water for irrigation will always be general in nature and applicable under average use conditions. Many schemes of classification for irrigation water have been proposed. Ayers and Westcot (FAO 1985) classified irrigation water into three groups based on salinity, sodicity, toxicity and miscellaneous hazards, as ...

This empirical research investigates the factors influencing the adoption of three irrigation technologies using a probit statistical model: water wheel (WW), water pump (WP), and weir (WR) irrigation technologies as well as their economic returns per unit of rice cultivated area. The influencing factors were categorized into demographic, socioeconomic, topographical, institutional, and attitudinal factor groups by 207 rice-growers in the Chaiyaphum province in northeastern Thailand. The results revealed that the land holding size, farm income, and water use association (WUA) membership factors were highly positively associated with the WW adoption. Meanwhile, age, farm income, skills training, and WUA membership were negatively correlated with the WP adoption. Nevertheless, proximity to a water source and upstream farmland location were positively correlated with the WP adoption. The WR adoption was positively associated with age but negatively correlated with the land holding size, upstream farmland

This ratio quantifies the proportion of sodium (Na+) to calcium (Ca++) and magnesium (Mg++) ions in a water sample. In the soil, calcium will flocculate (hold together), while sodium disperses (pushes apart) soil particles leading to poor soil condition. Many factors including soil texture, organic matter, crop type, climate, irrigation system, and management impact how sodium in irrigation water affects soils. Sodium in irrigation water can cause toxicity problems for some crops, especially when the water is applied with a sprinkler system. SAR and ECw are interdependent and thus irrigation suitability is characterized by both values. The following is a breakdown of the general classifications of irrigation water based upon the SAR values. Course Sand to Fine Sandy Loam: maximum EC of 3000 micromhos per centimeter and maximum SAR of 12; Loam and Silt Loam: maximum EC of 3000 micromhos per centimeter and maximum SAR of 9; Very Fine Sandy Loam to Silty Clay Loam: maximum EC of 2250 micromhos per ...

Grant County, WA) Landau Associates is assisting Four Cross Ranch to obtain Article 28 and Phase I Water Service contracts with the Quincy-Columbia Basin Irrigation District (QCBID) to develop over 1,500 acres of center pivots in the High Hills area of Irrigation Block 91 in the north portion of the Quincy Basin. Water Service contract issuance is contingent on drainage approval from the Bureau of Reclamation. The High Hills is a 14-square mile area between lower Grand Coulee and Dry Coulee and directly above Soap Lake. The lake is unique in that it has no surface water inlet or outlet and no groundwater outlet (all inflow is from groundwater; all discharge is from evaporation). Initial development of the Columbia Basin Project in the late 1940s and early 1950s led to flooding of Soap Lake and a decrease in salinity. The Bureau had deferred irrigation of the High Hills because of the unknown impact of irrigation return flows from spray irrigation on recharge to Soap Lake. Stratigraphy beneath ...

Furthermore, the assumption is made that 100 ha of land is available for the production of maize while 2 water supply scenarios are considered. Scenario 1 is characterised by a situation where enough water is available to irrigate 100 ha of maize without sustaining any crop yield loss due to salinity (α = 1). Thus, the farmer needs to reduce his area irrigated to release water for leaching purposes when irrigation water quality deteriorates further. With Scenario 2 water supply is assumed to be 10% more than that of Scenario 1 (α = 1.1). However, the area that can be irrigated remains at 100 ha. Scenario 1. Figure 2 shows the tradeoff that exists between deteriorating irrigation water salinity and the on-farm margin above specified costs (a), the marginal value of irrigation water (b), soil water salinity (c), amount of water used to leach excess salt from the soil (d), the area under production (e) and crop yield (f). The results in the graphs show that no tradeoff is modelled when the ...

Bonneville Power Administrations WaterWise program is an agricultural initiative that has evolved into a comprehensive effort that results in the triple benefits of energy and water savings and often increased crop yields thanks to the precision application of water. WaterWise dates back to 1979 when BPA first addressed irrigated agricultures energy use by developing a pilot program that focused on pump testing and evaluating farmers irrigation systems. A few years later BPA instituted the program on a regional basis and added incentives to the program for equipment retrofits. Then in 1991 these early programs were dramatically ramped up to create WaterWise, a program that addresses the needs of farms of varying sizes. In its current form, WaterWise is implemented by 39 retail utilities within BPAs service territory.. ...

The main objective of any irrigation program is the development of an efficient water management system to sustain crop growth and development and avoid physiological water stress in the growing plants. Field experiment to evaluate the effects of some soil moisture conservation practices on yield and water use efficiency (WUE) of maize was carried out in three locations (i.e. Mubi and Yola in the northern Guinea Savannah and Ganye in the southern Guinea Savannah of Adamawa State, Nigeria) during the dry seasons of 2013 and 2014. The experiment consisted of three different irrigation levels (7, 10 and 12 day irrigation intervals), two levels of mulch (mulch and un-mulched) and two tillage practices (no tillage and minimum tillage) arranged in a randomized complete block design with split-split plot arrangement and replicated three times. The Blaney-Criddle method was used for measuring crop evapotranspiration. The results indicated that seven-day irrigation intervals and mulched treatment were ...

4) Drip nozzles.. The head consists of a pump to lift water and produce the desired pressure (about 2.5 tmosphere) and to distribute water through nozzles. A fertilizer tank for applying fertilizer solution directly to the field along with the irrigation water and filter which cleans the suspended impurities in irrigation water to prevent the blockage of holes and passage of drip and nozzles. Mains and sub mains are normally of flexible material such as black PVC pipes. Laterals or drip lines are small diameter flexible lines (usually 1 to 1.25 cm diameter black PVC tubes) taking off from the mains or sub mains. Laterals are normally laid parallel to each other. Lateral lines can be up to about 50 meters long and are usually 1.2 cm diameter black plastic tubing. There is usually one lateral line for each crop row. By laying the main line along the center line of the field, it is possible to irrigate either side of the field alternately by shifting the laterals. A pressure drop of 10 percent is ...

Figure 2. Definition Sketch of an Irrigation System The approach which has been applied to irrigated agricultural development in the past is characterized by separating the development of water resources from the management aspects of water resource utilization. Therefore, the record shows development being emphasized greatly while management is most often neglected. This orthodox approach has been used almost exclusively in the western United States with reasonable success. However, as water resources become more fully utilized, the necessity for meeting new water demands (along with physical, socioeconomic, and political problems of water quality degradation) require that we reject much of the conventional wisdom of the past. It should also be obvious that many other countries have neither the time nor the resources that many western irrigated regions had to utilize in their development. Pressures created by rapidly rising population rates alone will force them at some point to re-evaluate ...

The amount of energy saved through recycling depends upon the material being recycled and the type of energy accounting that is used. Correct accounting for this saved energy can be accomplished with life-cycle analysis using real energy values. In addition, exergy, which is a measure of useful energy can be used. In general, it takes far less energy to produce a unit mass of recycled materials than it does to make the same mass of virgin materials.[80][81][82]. Some scholars use emergy (spelled with an m) analysis, for example, budgets for the amount of energy of one kind (exergy) that is required to make or transform things into another kind of product or service. Emergy calculations take into account economics which can alter pure physics based results. Using emergy life-cycle analysis researchers have concluded that materials with large refining costs have the greatest potential for high recycle benefits. Moreover, the highest emergy efficiency accrues from systems geared toward material ...

Salinity management is particularly important in dry regions that rely on irrigation. Many irrigation operations recycle irrigation water. Over time, as water is recycled again and again, salt levels in the water build up and salt is deposited in the soil, which reduces the soils ability to absorb water and air. As salt levels in irrigated land increase, a white or black crust can form at the surface of the soil. Plants start to suffer damage when soil sodium concentration exceeds 230 milligrams per liter, and chloride concentrations in soil exceed 350 milligrams per liter. Periodic deep irrigation with fresh irrigation water helps remove salt from soil.. ...

The purpose of this study is to evaluate the efficiency of irrigation water use and allocation in the Waihou Catchment. It follows on from similar work for other parts of the Waikato Region. It will further extend the understanding of water use and allocation in the Region and contribute to the development of water management policy and planning.. The surface water resources of the Waihou Catchment are close to full allocation. Future demand for surface water will need to be met from improvements in efficiency of current water uses and allocations. Irrigation accounts for 50 percent of the daily take, and therefore any improvements in on-farm water use and/or allocations will be a major benefit. This is applicable to not only the Waihou Catchment, but also to other catchments where water resources are a constraint to future development.. Irrigation Efficiency and Water Allocation in the Waihou Catchment ...

Climate change is causing growing variability and uncertainty in rainfall in Africa. Since the continents food production systems are dominantly rain-fed, these changes are putting food security at even higher risk. In order to reduce this dependency, institutional reforms in the agricultural water sectors have become a priority in research and policy.. In this report, Atakilte Beyene, senior researcher at the Nordic Africa Institute, together with twelve researchers based in Africa, studies current agricultural water reforms in Kenya, Tanzania, Uganda, and other East African countries. The report consists of four case studies and an introductory section. The first case study evaluates the performance of community participation in water resources governance in the Mount Kenya Region. It uncovers the implication of a ban on traditional institutions on water security at a catchment level. The second case analyses the prospects of introducing pro-poor water schemes in conditions where climate ...

Actually, leaving water out in the sun may promote algae growth. The algae comes from stuff floating around in the air that gets in the water while you are filling the container. I have a 275 gallon LDPE tote on a trailer that I keep for wash water or other needs. I use groundwater from an aquifer about 75 ft. deep and this water is sterile when it is pumped from the well. Unless I disinfect the water in the tote, algae will start to grow and the water will turn green. Once disinfected, this doesnt happen, since the tote is capped and nothing gets in. I keep my irrigation water in blue LDPE drums that are opaque. I dont mind algae in my irrigation water, but it plugs the drippers ...

Water cards. Pink and light blue cards were used to represent water. One pink card was used as the equivalent to the volume of enough water to transplant and irrigate 0.1 ha of rice. Pink cards represented water used in the first cycle (first week of June to October) and light blue cards represented water used in the second cycle (third week of June to October). This means that farmers could place only one water card in one plot to indicate that that plot has been planted to rice. This card could be sold, exchanged, or used for transaction among villagers in a community or between farmers of the two communities. The game facilitator issued water cards in correspondence to the rainfall type. In the normal-rainfall season, Thruelpa received 5 water cards, Chhep 3 cards, Chatho 2 cards, and Lhangchu 1 card. During the low-rainfall pattern, the water provision was reduced by one unit, that is, 1 card less for each category ...

nt low levels of available soil P, thus requiring P inputs for productive agriculture. However, constant P inputs result in accumulation of soil P (legacy P), increasing risk of eutrophication of waterways. Efficient P use of agriculture require improvements in utilisation of legacy P. The objective of this work was to investigate and quantify the impact of contrasting agricultural land uses and management on the nature and dynamics of P. Three long-term, replicated field trials were selected: i) long-term irrigation trial, Winchmore, New Zealand; ii) long-term pig slurry inputs, Santa Catarina, Brazil; iii) long-term ecology trial, Lincoln, New Zealand. Four experiments were conducted. The first study investigated the impact of 62 years of irrigation on the amounts and distribution of soil profile P to 100 cm under grazed pasture. Despite identical P inputs, total soil profile P accumulation was inversely proportional to water input rates (6423, 5908 and 5054 kg P ha⁻¹ for the control, low ...

The Oakdale Irrigation District Board of Directors unanimously approved the implementation of a demonstration project for Total Channel Control (TCC) on the Claribel and Cometa laterals by Rubicon Systems, an Australian company that manufactures water control gates, precision water measurement instruments using wireless technology, and monitoring and control software that enables water authorities to manage and operate their systems more efficiently.. The cost will be shared with Rubicon. The districts estimated costs will be at $1 million to come from bond finances secured in 2009 and Rubicons costs are at $1.53 million. The project is expected to move forward at the end of the 2011 irrigation season. More specifically, Rubicon will install approximately 37 gates to the Claribel Lateral from the Southside Regulating Reservoir to its end (spill) and the upper Cometa Lateral from the Northside Regulating Reservoir to the border between Districts 9 and 10.. OID General Manager Steve Knell said ...

Cities are highly vulnerable to water shortages. Lack of irrigation water, which makes up the largest proportion of global water use, can have severe social and economic consequences in urban areas. Reducing this vulnerability requires understanding how water resources vary over time, both regionally and globally. Brauman et al. developed a metric based on seasonal and drought-related depletion of water resources to provide more accurate estimates of global water scarcity. Factoring in these variables into annual global water models, the number of watersheds experiencing significant depletion increased 15-fold. Because nearly 50% of large cities and over 70% of croplands fall short of their water needs at some point in the year, rebalancing their water budgets should be a top priority..

By Nick Gevock, The Montana Standard, Butte Jun. 17--Clark Canyon reservoir remains about a quarter short of its long term average water supply despite the recent several weeks of cool, wet weather. The reservoir as of last week was holding about 121,000 acre feet of water, roughly three quarters its average of 167,000 acre feet for this time of year, said Dennis Miotke, manager of the East Bench irrigation district. Its only 9,000 acre feet more than last year but a big improvement over the past few years. "Its in pretty good shape for this time of the year," he said. "It could be better but weve had it a lot worse." The good news is the reservoirs water level is roughly holding steady as irrigators pull water from it to start putting on crops. Miotke said the dam is releasing 350 cubic feet per second, which is less water than it normally would be letting go for this time of year. With a strong snowpack in the mountains and healthy rains in recent weeks, the release of water hasnt been ...

Thatch is the layer of undecomposed leaf blades, stolons, roots, and crowns intermingled with soil. Leaving mowing clippings on the lawn does not cause thatch because clippings are readily broken down by microbes in the soil. Thatch development is greatest in grass that is overfertilized or overwatered. An excessive thatch layer reduces water penetration and can bind up fertilizer or pesticides. In severe cases, roots may be seen actually growing aboveground and rooting into the thatch layer. This is a very unhealthy condition and leaves the lawn vulnerable to many stresses. Thatch layers can develop in St. Augustinegrass, especially when fertilization or irrigation rates are high. If the thatch layer exceeds 1 inch, it may be removed by vertical mowing, or "verticutting," in early spring to midsummer. Verticutting uses vertical blades that slice through the thatch and slightly into the soil, resulting in much of the dead material being removed from the top of the lawn. A 3-inch spacing between ...

Osmoreceptors in the anterior hypothalamus provide the stimulus for vasopressin (ADH) release [J Lab Clin Med 101: 351, 1983] starting at a threshold of 280 mOsm/L. In the absence of ADH, serum osmolarity can still be maintained as long as consciousness permits thirst and consumption of fluids. note that ADH can also be stimulated by increased sympathetic tone (pain, hemorrhage, hypovolemia [Am J Physio 236: F321, 1979]), elevated ICP [J Neurosurg 46: 627, 1977; Acta Neurochir 77: 46, 1985; Acta Neurol Scand 74: 81, 1986], nausea, opiates, and carbamazepine.

SUN Columnist. Last week, I discussed drought management planning for cattle ranchers and gave an introduction to small acreage pasture management.. Archuleta County is like many areas in Colorado that have seen many subdivisions spring up over the last few years. Many of the new residents purchased small acres in order to keep horses or other animals for their personal use. Many of these residents may not have a deep background in agriculture or ranch management.. The Archuleta County CSU Extension receives questions each year pertaining to small acreage pasture management. I will discuss some general pasture management practices here that will help you care for pastures and protect your valuable forage resources. Most of the small acreage in these areas are not irrigated and I will address these as being non-irrigated.. The drought we had in 2012 has magnified the importance of taking care of our forage resources. One only has to drive around our neighborhoods to see impacts of the drought and ...

The rotation in Minnesota is entirely different. The crop again is in for two years, then harvested. After that, a neighbor plants wild rice on those acres for two years. After each rice harvest, the fields are flooded with water for 60 days. This is based on an old University of Minnesota recommendation for soilborne disease control, and flooding is facilitated by the bordered fields on that farm. The next year, soybeans are planted for one year, with another horseradish crop to follow that.. Traaseth acknowledges that he hasnt carried out any large-scale experiments to verify that either of these methods is the best way to achieve disease control, but he says that as a result of this program, the disease complex does not persist and their fields are clean. In fact, as long as this rotation is in effect, he does not consider that the farm has a disease problem, even though they use their own lateral roots for sets just as everybody else does. In fact, their clean sets are in demand from other ...

In recent years development planners have been focussing on the expansion of irrigated lands in order to safeguard the nutritional basis for a growing population. In the rural areas of the subtropical belts extending the potential growing period, expanding the area covered by agricultural fields and improving their productivity on a sustainable basis are components of quite common and widely applied development strategies. There have been many successes in this approach, especially from marginal regions where dependence on monsoon rains have been superseded by a steady supply of irrigation water from perennial sources. Mountain regions have been quite marginal to such planning as projects depend on large-scale structures, with major dams creating storage reservoirs to feed canal networks the size of medium rivers in the plains and piedmont areas. The water supply for such projects was tapped from the huge glaciated regions up in the mountains, which have been labelled the water towers of Asia, ...

The sunny Salinas Valley holds a dark mystery: Why, in the past decade, have nine Escherichia coli outbreaks been linked to produce grown here?. Its still unknown why this fertile land has been hit by what an FDA official calls "significant" crop contamination. Throughout the picturesque terrain here, questions swirl.. Has cattle waste contaminated irrigation water? Does contaminated soil blow in the wind? Do birds feeding on cow manure carry E. coli?. Is such contamination inevitable to farms so big that the area is known as "The Salad Bowl" to the nation and world? Over 10 years, E. coli outbreaks linked to produce grown here have sickened more than 300 people and killed three.. Not even federal or state authorities know why. "Thats a very good question, and we dont have an answer to that," said Dr. David Acheson, chief medical officer for the Food and Drug Administrations Center for Food Safety and Applied Nutrition. "Certainly huge amounts [of vegetables] are produced there, which is ...

It takes a lot of work - and a lot of water - to grow healthy trees and shrubs for Canadas ornamental plant sector. The industry, which boasts approximately 3,500 nurseries across Canada, uses an estimated 190 million cubic metres of water every year.But new research suggests this is two to three times more water than healthy trees need. And soon a new tool will be available to help nursery managers determine when to turn on-and turn off-the hose.Jared Stoochnoff, a University of Guelph graduate student in the School of Environmental Sciences Controlled Environment Systems Research Facility, is pioneering a new irrigation management strategy designed to reduce water consumption and mitigate the environmental impact of ornamental nursery operations."Because many nursery irrigation managers lack reliable ways to quantitatively predict a plants actual water requirements, they tend to err on the side of caution and overwater," Stoochnoff says. "This results in unnecessarily high water and ...

The way we see the world shapes the way we treat it. If a mountain is a deity, not a pile of ore; if a river is one of the veins of the land, not potential irrigation water; if a forest is a sacred grove, not timber; if other species are our biological kin, not resources; or if the planet is our mother, not an opportunity -- then we will treat each one with greater respect. That is the challenge, to look at the world from a different perspective." David Suzuki ...

The quirky thing about siblings is that even though we all grew up in the same family and under the same roof, we all have our own point of view of the family happenings. As childhood compatriots they share in the joys of summer, of playing in the irrigation water on a hot day, in the excitement of trick-or-treating and getting the crap scared out of you at a spooky neighbors house. In the anticipation of Christmas morning. But also in the mundane living that is life. When it seems the parents are being cruel or we are utterly bored out of our minds on an idle Tuesday afternoon at 3pm. Its part of growing up to have an older sibling stick up for you when you are having trouble at school AND to have that same sibling tell you to stay out of their room or quit touching their stuff. The bonds forged then last long into being a grown up and the spaces and distance that replace the few steps down the hall to their bed on a dark night ...

Policy analysis is complicated by the myriad of benefits and costs generated by the use of natural resources. This study develops three benefits that must be considered in the granting of a consumptive use permit for water filed by Adena Springs Ranch, east of Ocala, Florida. This ranch is hoping to expand into grass-fat beef; but to do so, it needs additional water for irrigation. Specifically, our analysis considers the potential gain from the ranch, the potential negative effect on existing permit holders and environmental uses of water, and the possible positive value generated by the increased surface flow for other recreational users in eastern Marion County.

Ontogeny recapitulates phylogeny. Who would have thought Ernest Haeckels famous and scientifically nerdy maxim would be central to the theme of one of the most performed plays of the early 21st century? But Peter Sinn Nachtriebs BOOM embraces that theme and explodes it to cataclysmic comic proportions. BOOM is a combination of bedroom farce and locked door mystery. It is ironically a retrospective about the end of the world as we know it (to quote R.E.M.), satirizing science, relationships and the blasé despondency of millennials.

BRUCKER KELLING, Monica et al. Irrigation regime and water retaining polymer doses in morphological and physiological characteristics of Cordia trichotoma seedlings. Bosque (Valdivia) [online]. 2017, vol.38, n.1, pp.123-131. ISSN 0717-9200. http://dx.doi.org/10.4067/S0717-92002017000100013.. The objective of this research was to define which irrigation regime, whether or not combined with water retaining polymer doses added to the substrate, is recommended in the production of Cordia trichotoma seedlings. The substrate was used with different dosages of water retaining polymers (0, 1.5, 3.0 and 4.5 g L-1). After emergence the seedlings were subjected to different irrigation regimes (4-4-4, 4-8-8, 4-8-12, 8-8-8, 8-12-12 and 12-12-12 mm day-1, alternating them every 60 days). The experiment was conducted in a completely randomized design in a split plot scheme, where the main plot was formed by the different irrigation regimes and subplots by doses of a hidroretentor polymer. After 180 days of ...

Cholinesterase (ChE) activity was used as a biomarker for assessing exposure of common carp (Cyprinus carpio) to organophosphate and carbamate insecticides from irrigated agricultural waters. Carp were collected from a lake (Royal Lake) that receives most of its water from irrigation return flows and from a reference lake (Billy Clapp Lake) outside of the irrigation system. Results indicated that the mean whole-brain ChE activity of carp from Royal Lake (3.47 μmol/min/g tissue) was 34.2% less than that of carp from Billy Clapp Lake (5.27 μmol/min/g tissue) (p = 0.003). The depressed ChE activity in brain tissue of Royal Lake carp was in response to ChE-inhibiting insecticides detected in water samples in the weeks prior to tissue sampling; the most frequently detected insecticides included chlorpyrifos, azinphos-methyl, carbaryl, and ethoprop. Neither sex nor size appears to be a covariable in the analysis; ChE activity was not correlated with fish length or weight...

Symptomatic vasospasm after SAH has been the most serious problem in treating ruptured aneurysms. In 1980, Fisher et al13 reported that vasospasm was found in almost all cases with a thick and widespread subarachnoid clot on CT scan (group 3 according to their grading scale). Their study clarified that the volume of the clot correlated with the occurrence of symptomatic vasospasm and/or neurological deterioration due to vasospasm. On the basis of these results, we hypothesized that the best means to prevent symptomatic vasospasm might be to remove as much of the clot as possible, as early as possible.. Irrigation therapy with UK was first reported by Yoshida et al in 1983.16 However, their results did not demonstrate significant benefit. In their study, relatively low UK concentrations (,48 IU/mL) and different irrigation systems were used than in our present study. We had previously performed cisternal irrigation therapy with UK and ascorbic acid. Of the 217 patients in that study,2 symptomatic ...

Increased aflatoxin contamination in corn by the fungus Aspergillus flavus is associated with frequent periods of drought and heat stress during the reproductive stages of the plants. The objective of this study was to evaluate the relationship between aflatoxin contamination and physiological responses of corn plants under drought and heat stress. The study was conducted in Stoneville, MS, USA under irrigated and non-irrigated conditions. Five commercial hybrids, P31G70, P33F87, P32B34, P31B13 and DKC63-42 and two inbred germplasm lines, PI 639055 and PI 489361, were evaluated. The plants were inoculated with Aspergillus flavus (K-54) at mid-silk stage, and aflatoxin contamination was determined on the kernels at harvest. Several physiological measurements which are indicators of stress response were determined. The results suggested that PI 639055, PI 489361 and hybrid DKC63-42 were more sensitive to drought and high temperature stress in the non-irrigated plots and P31G70 was the most tolerant among

The European Food Safety Authority recommends that: (1) a full description of the methodology used in reviewing and assessing the literature, regulations and guidelines is provided; (2) there is a separate category for feed crops and pasture; (3) there is explicit mention of the fact that the tolerable level of risk used in the World Health Organization guidelines is formally accepted by European risk managers, and that information is provided on the data supporting the impact of the minimum quality requirements on public and animal health; (4) relevant publications on concentrations, ...

Understanding malaria vector mosquitoes and their infectivity dynamics is of importance in setting up intervention and control programmes. Patterns of malaria transmission have been shown to differ between non-irrigated and irrigated semi-arid areas of eastern Sudan. However, very little information is available regarding malaria transmission dynamics along the seasonal rivers basin. Such information is required for the design of effective vector control strategies. A longitudinal study for mosquito sampling using pyrethrum spray catch (PSC) was conducted in two villages (Koka & Um Salala) along the Rahad River basin from December 2005 to October 2006. The Plasmodium falciparum circumsporozoite (CSP) and human blood index (HBI) were detected by ELISA. Three seasons were considered and the surveys represented cool dry, hot dry and rainy seasons were November - February, March - June, July - October, respectively. The CSP was compared between the seasons and populations using Chi-square test. The

Predisposing factors of Rice Tungro DiseaseFactors for the development of Rice Tungro Disease1. The outbreak of rice tungro disease is the result of several factors like availability of virus source (primary inoculum), presence of host susceptible to both virus and vector, right growth stage of the host, availability of vectors and favourable climatic conditions.2. Shortage of irrigation water may also promote tungro incidence because farmers are forced to plant asynchronously.Rice Tungro Virus1. Rice tungro bacilliform virus (RTBV) is a reverse-transcribing DNA virus which, in association with an RNA virus, Rice tungro spherical virus (RTSV) develops Rice tungro disease.
