Scenario analyses and synthesis (WP5)
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.
