Sustainable soil management is a major concern for cotton farms in Burkina Faso due to population growth, the expansion of cotton cultivation and suboptimal practices of soil fertility management. The study of these practice and the evaluation of their impacts on soil and cotton production was performed in the centre and west of Burkina Faso. The analysis of practices and their impacts were implemented by surveys at 315 farms and the evaluation of agronomic and soil impacts was conducted in each cotton zone on 45 fields.
