This poster provides an overview of the Long Term Research Activity 10 of Phase IV of the SANREM CRSP in two upland and two lowland areas in Mt. Elgon region of Kenya-Uganda border: Kapchorwa and Tororo Uganda; Trans Nzoia and Bungoma, Kenya. The project aims to assist farmers and other stakeholders in determining whether soil-building practices result in healthier soils and economically higher yields. They will have identified, developed and tested tools for reducing soil disturbance over this 5 year project. The research will also result in defined policy and regulatory constraints to agronomic and market innovation.
