Modelling Impact of Adjusted Agricultural Practices on Nitrogen Leaching to Groundwater

Goulding, K. Nitrate leaching from arable and horticultural land. The application of nitrogen fertilizer to arable and horticultural crops is very cost-effective, stimulating its use. The Programme has led to the development and testing of methods to measure nitrate leaching, the identification of 'leaky' crops, soils and practices, and strategies to optimize the use of fertilizer nitrogen. Data have been used to construct and test models of nitrate leaching, which in turn have been used to evaluate the leakiness of potential rotations.

Current best practice to minimize nitrate leaching requires measures to improve the efficiency of nitrogen use by crops, combined with measures to protect soil nitrogen from leaching during the late autumn to spring drainage period.

This involves consideration of many factors: an appropriate crop variety must be chosen; a green cover must be maintained for as much of the year as is practicable; crops should be drilled early; fertilizer requirements should be calculated using a recommendation system and allowing for soil mineral nitrogen and any manures applied; fertilizers should be spread evenly with a properly calibrated spreader, perhaps using split applications; starter fertilizers and banding of fertilizers should be used where appropriate to reduce losses from vegetables; pest and disease infestation must be minimized; any irrigation must be applied carefully with scheduling.

Research is now moving on to study whole farm systems and the interactions between losses of nitrogen and other pollutants to the environment with the aim of minimizing total environmental impact.

Leaching (agriculture)

Mark Brady. Arable nitrogen emissions contribute to serious water-quality problems around the globe. To reduce pollution of the Baltic Sea, Sweden has implemented a comprehensive scheme of nitrogen abatement instruments; a uniform nitrogen fertilizer tax, green payments subsidies , and land-use regulations. The purpose of this study was to evaluate the relative cost-efficiency of the scheme and to analyze the implications of agricultural policy for the least-cost solution. Due to the expanse and heterogeneity of the study area, a spatially distributed nonlinear mathematical programming model, which linked changes in agricultural production practices on crop farms in Southern Sweden to coastal nitrogen load, was developed.

For , yield data from calendar years were averaged and divided by the yield for each crop Exhibit A, page 6.
