Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
Technical Summary
Models are an important means to improve our understanding through the testing of different hypotheses and scenarios. In this project we seek to apply integrated knowledge in the form of computer simulation models of agroecosystems to global environmental change (such as the effects of climate change, water and nutrient stress) at different spatial and temporal scales
Specific modelling targets:
1. A model of the formation and movement of DOC in soil that will allow us to explore (i) the movement of carbon from surface to subsoil, (ii) the role played by dissolved organic matter in altering the physical environment of soil.
2. A combined model of the effects of drought, strong soil, nutrient stresses on plants growing in soils with changing environmental condtitions that will allow us to explore the interacting effects of these stresses in agricultural ecosystems locally and globally.

| Description | Intercropping different species is potentially able to reduce the amount of nitrate leaching from agriculture Nitrogen in soils for global ecosystem models can be adequately estimated from soil carbon and texture and latitude |
| Exploitation Route | Water companies and retailers interested in reducing N emissions may be interested in our strategies for reducing Losses of N to the environment Global ecosystem models require initialisation. Previous models forecast emissions of CO2 from soil without taking account of the nitrogen cycle we have developed means to do this |
