WP5.1 Soil-crop modelling and environmental assessment
A typical crop rotation and crop management for organic wheat growers will be constructed from the survey in WP1. Assessment of the changes in crop rotation and crop management practices will be performed using the FASSET (Olesen et al 2002) and Azodyn-Org (David et al 2004) soil-plant-climate models, which have been thoroughly tested for use in organic farming systems. These models effectively capture effects of various cropping systems and input level on crop production, grain protein (David et al 2005c) and soil organic matter (Berntsen et al 2006) and include competition between species and simulation of legume-cereal intercrops (Berntsen et al 2004). The models will be used to evaluate effects of modifications of crop rotation and crop management practices as suggested by WP2 on grain yield and protein, soil organic matter levels, N leaching and nitrous oxide emissions. This will be performed by setting up these models for several sites in Europe, corresponding to the experimental locations using the soil and climate characteristics. The models will be run for several years of climate data for each site to account for climatic variation, and the results will be compiled and compared across sites and management practices to get a total environmental evaluation of the crop management practices.

 WP5.2 Economic assessment
An economic simulation model will be developed analysing the economic impacts of these innovations for typical quality-wheat producing farms in CH, IT, DK and FR. During the 3rd project meeting, the economic results explored in WP2 and WP3 will be evaluated for 10 typical farms producing quality wheat in the partner countries. The economic simulation model will simulate the financial effects for varying levels of yields, costs and prices and will provide information about the sensitivity and robustness of the results. Furthermore, the limitations and constrains for on-farm implementation will be identified.
