Improving the Economic and Environmental Performance of Cropping Systems with Peas, Oilseed Rape and Wheat


Optimising crop rotation according to economic and environmental criteria allows us to improve their performance. As part of the CASDAR-PCB Project , various field-crop rotations in France were studied using the SALCA method.

The studies were conducted in the three French regions of Bourgogne, Moselle and Beauce. Our regional partners selected and described a number of representative and especially promising crop rotations. The modelling and LCA calculation involved the combinations of previous crop and subsequent crop. This permitted the efficient calculation of a large number of crop rotations with a limited number of crop combinations.

Results showed the use of nitrogen to have the greatest influence on environmental impacts. A reduction in nitrogen applications has a favourable effect on both the environmental impacts per unit of area and on eco-efficiency (environmental impacts per € gross margin). Such a reduction can be achieved by introducing legumes into the crop rotation, or by reducing N-fertiliser applications in the fertilised crops.
