To quantify nitrate leaching following cultivation of grassland for arable crops - NT0602

Large areas of established grassland are broken up each year into arable cropping or reseeded. Soil cultivation stimulates mineralisation of soil organic matter and the production of nitrates. This effect needs to be quantified on sandy and shallow chalk soils in order to develop useful guidelines for grassland management in Nitrate Sensitive Areas. The objectie is to quantify nitrate leaching for 3 years following autumn or
spring ploughing, or surface cultivation, of established grassland and subsequent arable cropping on sandy and shallow chalk soils. The work follows from recommendations contained in the CSG Special Topic Review on `Nitrate leaching`. This experiment will contribute to the understanding of the factors influencing nitrogen cycling in grassland systems and the amounts of nitrogen moving down different pathways.
