Studies on nitrogen use and leaching in rotation and monoculture cereal cropping (Previously NT0112) - NT1817

This study will aim to provide guidance on management practices which minimise the extent of nitrate leaching. It will be composed of the following objectives: 1. To monitor effects of 3 levels of husbandry and 2 N rates on nitrate leaching and gross margin in a typical arable rotation for the Lincolnshire Heath; 2. To investigate whether N applied to "crop requirements" is likely to cause an environmental hazard in the sensitive area of the Jurassic limestone of Lincolnshire; and 3. To monitor effects of 2 levels of straw disposal and 2 N treatment rates on nitrate leaching and gross margin in continuous winter barley. A long-term trial will also be undertaken to assess effects of long-term reductions in N use on cereal yields, and to monitor changes in soil N reserves.
