Soil fertility in Kenya is poor. There is a lack of locally developed specific soil management strategies to reverse nutrient imbalances. The objectives of this project are to 1) improve soil fertility and food crop yields on small scale farms in Western Kenya; 2) strengthen research capacity of MMUST in relation to soil management; 3) develop on-farm quality composts using locally available materials; 4) improve soil physical and chemical properties through application of quality composts; and 5) improve the yields of maize and beans and community food security through application of quality composts.
