Étude comparative physico-chimique et biologique d’un sol conduit en semis direct et en labour conventionnel

Abstract

The importance of physical-chemical and biological analysis of agricultural soils allows farmers to evaluate the levels of physical and chemical fertilization of soils and to adapt to supplementary fertilization programs according to the needs of the soils and cultures. The analyzes allow the farmer to: - Know the state of its soil, its evolution and its development. - Get the best performance at the level of productivity. - Maintain production costs. - Protect the environment
