Soil Nutrient Dynamics
- Optimisation of nitrogen mineralization from winter cover crops and
utilisation by subsequent crops (DEFRA)
Field and on-farm trials to assess the fate of nitrogen from winter cover crops and to investigate ways of optimising the use of this nitrogen by subsequent cash crops in the organic rotation whilst minimising nitrogen leaching. The data generated is being used to refine and test HRI's computer models for nitrogen mineralization with the aim of developing them for use by organic farmers.

- Utilising Nitrogen in cover crops (DEFRA)
A desk study to draw together the results of all DEFRA-funded work on cover crops which has been conducted over the past ten years. Gaps in our knowledge in this area will be identified.

- Developing the use of green waste compost on agricultural land
(Wyvern Waste Services Ltd)
To investigate the use of green waste compost on agricultural land by assessing its effect on plant growth, soil nutrient status, soil structure and impact on the environment. Long term trials have been established within conventional arable and organic vegetable rotations.

- Understanding soil fertility in organically farmed soils
To provide a better understanding of the nutrient cycling aspects of soil fertility in organically farmed soils, targeting the processes involved and their controlling factors (including the role of biological diversity). This will enable better advice to be given to farmers to help optimise the use of resources and reduce the environmental impact of agriculture.

- The environmental implications of manure use in organic farming
A study to assess the compositional quality of animal manures produced on organic farms, to review the rules and regulations surrounding manure handling and to examine potential loss pathways which are specific for organic situations.
