Digital Soil Map to Help Farmers

Uganda will be soon benefit from an $18 million digital map of Africa's depleted soil. The project, sponsored by the Gates Foundation, will collect samples of soil from different regions. Composite samples of 12 or more cores from one region will be analyzed for their pH content, levels of phosphorus, potassium, calcium, magnesium, zinc and manganese. Knowing more about what kind of soil they are working with and what fertilizer would be best, farmers can be more effective with their agricultural techniques.
