SARIA I: The effect of rotation and organic/mineral input on Sorghum yield and soil fertility
This experiment has been added by the GLTEN Curators using existing published sources.
- Objective
- To evaluate the fertility of soils under different management systems.
- Description
- Results from Saria I indicate that under Sudano-Sahelian conditions, soil organic matter and crop performance were better maintained using organic resources with a low C/N ratio (manure) than through organic amendments with a relatively high C/N ratio (straw). Urea improved the effect of the organic amendments with high C/N ratio (straw) on crop yield and SOM concentration.
