Biochar and cocompost: an option for sustainable fertility management of leached tropical ferruginous soils

The current challenge for agriculture in Burkina Faso is to find innovative options for sustainable fertility management that use accessible technologies to increase agricultural production while preserving the soil An experiment to recycle nutrients through the production of biochar from cotton stalks was carried out in the village of Massala in western Burkina Faso The association of biochar with the composting process called co composting was tested on 03 types of
soil The experimental design used is a BCR with 03 treatments and 04 replicates to determine the effects of the different treatments on cotton yield for different soil types The area of each the elementary parcel was 120 m2. The 03 soil types according to the CPCS classification 1967 are FLC, FLIMP and FLIPP
The objective of this study is to evaluate the effects of biochar based on cotton stalks in different fertilization formulas on the productivity of the 3 soil representative of the pedodiversity in western Burkina Faso in cotton cultivation
