Of the common plant nutrients, nitrogen in the nitrate form is the most water-soluble and therefore the most vulnerable to leaching. Anytime soil is bare and appreciable rain falls, nitrates are on the move. Nitrate can be present in the soil at the end of a cropping season if the crop did not use all the N applied. Water quality and nutrient management issues in the state have stimulated interest in re-evaluating these recommendations after more than two decades. From , we conducted on-farm trials in P in corn and soybean and 84 trials in K for corn and soybean in Ohio. This expanded issue of Pollution Prevention Northwest describes P2 approaches in both urban and rural areas. By addressing diffuse pollution sources holistically through watershed management and adopting practical P2 measures, communities and their businesses can improve the bottom line for .

Groundwater is vital for Canada’s health, environment and economy. Nearly a third of Canada’s population, some 10 million people, depends on groundwater for safe drinking water and more than 80 per cent of Canada’s rural population depends on groundwater for its entire water supply. Canada’s groundwater, however, is increasingly under threat from factors such as urbanization, climate.

While various levels of reduction in nitrate leaching achieved by optimizing management practices have been documented through soil, lysimeter and tile-drain sampling at a plot/field scale (e.g.
Oregon State University1, Corvallis, Oregon and Washington State University2, Puyallup, Washington. Nitrate can pollute groundwater if there is a substantial quantity present in the soil when leaching potential is high, usually in winter when precipitation exceeds evapotranspiration.
The Columbia Basin production area in central Washington and north central Oregon includes approximatelyacres irrigated by water from the Columbia and Snake Rivers. Growth and development Understanding how the onion plant grows and develops is a key part of developing a strategy to supply nutrients for optimum bulb yield and quality.

It may be useful on all elements in the periodic table from. Abstract: Cover crop performance depends largely on management factors that must be customized to particular farm situations and, therefore, is suited for on-farm research, with farmers involved in both management and evaluation.
Cover crop sequences that were successful in a research station study were tested over a variety of soils and. Nitrogen transformation models are essential in designing management options to minimize groundwater pollution that aim at reducing nitrate leaching (Ling and El-Kadi, ; Refsgaard et al., Goals / Objectives a) Elucidate factors to improve soil quality and nutrient-use-efficiency (NUE), b) Develop mgmt to increase NUE and decrease residual soil nitrate (RSN), c) Develop sustainable low/no-till practices for irrigated crops, d) Determine ways to prevent surface/ground water contamination, and enhance microbial mediation e) Develop/test/calibrate mgmt tools to evaluate best mgmt.
Nitrate Leaching from Injected Manure on Coarse-Textured Soils Since conservation tillage is often practised successfully on sandy soils, manure injection systems are needed for these fields. Since these soils are prone to leaching of nitrate, especially where the water table is shallow, special caution must be practised when injecting manure.

With enhanced nutrient and cropping management (Farmlet 3), a similar total yield comprised lower maize biomass but higher grass and cover crop biomass.
There was also more grain (not shown) and greater N recovery, and due to better growth of grass and cover crop, there was notably less nitrate leaching.
The goal of efforts to reduce nitrogen and phosphorus loss from agriculture to water is to increase nutrient use-efficiency. To do this, farmers attempt to balance the input of nutrients into a watershed from feed and fertilizer with outputs in crop and livestock produce, and also to manage the level of nitrogen and phosphorus in the soil.

Introduction. Projected increases in human population together with an improved diet indicate that current production of crops and trees will need to be raised substantially over the next few decades (Evans,Waterlow et al., ).The world’s population has already risen from billion in to its current 6 billion and is projected to be about 8 billion by (Fischer and Cited by: Addressing Nitrate in California s Drinking Water with a focus on Tulare Lake Basin and Salinas Valley Groundwater.

This thesis concerns groundwater quality with a detailed study of the Abbotsford-Sumas Aquifer and the high nitrate-nitrogen values that have been occurring for the past 20 or so years. Groundwater is becoming an increasingly scarce resource, both in terms of quantity and quality, worldwide.
Aquifers are generally poorly understood, dynamic and are an integral part of the hydrological cycle. In maize-based cropping systems, leaching of nitrate-nitrogen (NO3-N) to drainage tile and groundwater is a significant problem.
The purpose of this study was to assess whether a winter rye cover crop planted after silage maize or soybean harvest and injected with liquid manure could decrease soil NO3-N without reducing the yield of the following maize : Leslie A.
