Developing a systems-based modelling approach to understand and predict consequences of grassland soil managements for atmosphere and water environments

Lead Research Organisation: Rothamsted Research
Department Name: Unlisted


This modelling project focuses on the grassland soil system, studying the processes of interaction between plant shoots, roots, grazing animals, livestock derived organic matter, soil animals including microbes and their consequential affects on the wider environmental systems, particularly water and atmospheres.

This project is linked to the SoilCIP (Objective 2), which contributes a thermodynamic element to the modelling. There is also a special grassland rhizosphere systems model that provides the basis for assessing interactions and transfers, draws and interacts with information from the other projects in the 'Grassland, environment and soil systems' Strategic Programme Grant area.

The work of this project is generically interactive with the research involved in the other North Wyke Strategic Programme Grant area: 'Delivering Multifunctional Landscapes'.

Description 1. Development of a merged NW-Res NGAUGE and R-Res carbon model initiated

2. Development of a soil water balance model for North Wyke, with subsequent incorporation into the SIMSDAIRY model

3. Incorporation of soilwater balance model into a soil cracking clay model representative o f many grassland soils

4. Initial work to develop a phosphorus module for the SPACSYS systems model. This is incorporated into the current Developing Sustainable Systems ISPG.
Exploitation Route The models have been used in other projects, including those that inform policy
Sectors Agriculture, Food and Drink,Environment

Description The models that have been developed in this grant have been used in subsequent projects that have been funded both by research councils and defra. The latter feed directly into policy.
