Réussir sa transition en agriculture de conservation des sols

Abstract : In order to cope with the social demand and latest legal changes, the agricultural sector in France has to face numerous major challenges: reduction of 50% for all chemical inputs, to reach an certain energy effectiveness by reducing all fossil energy by 30%, finally, preserve soils’ fertility and biodiversity. Conservation Agriculture (CA) applies to meet the challenges. Indeed, by preserving the ecosystem, crops are being offered numerous of its the ecological functionalities. Nevertheless, the transition to Conservation Agriculture is far from being easy. Investigations had been led on members of the VivesciAgrosol, the pioneer of Conservation Agriculture. The goal was to assess on agricultural practices and to offer decision making rules in order to help other producers to realize their own transition to Conservation Agriculture. Ground cover, extended and diversified crop rotation and minimum tillage are crucial for maintaining good sanitary conditions for the crops (weeds, pests and diseases), as well as landscape ecology (agro-ecological infrastructures). Finally, the implementation of leguminous plants within these new agro-systems appears essential to cope with a sensibly different nitrogen management.
