Improving Soil, and Saving Money, in Eastern Uganda (1/2)

Sorghum farmers in eastern Uganda, working with scientists, have tested some lower-cost ways to improve their soil. Little rain and poor soil fertility are problems in that area, as in other parts of southern Africa. Experts from the Kawanda Research Institute in Uganda and the University of Nebraska-Lincoln in the United States did the research.

They say much of the soil lacks enough phosphorus and nitrogen. But for many small farmers, the cost of treating the soil is more than they earn from their crops. So the researchers suggest 5 methods that could decrease costs and increase production of sorghum. Sorghum is an important food grain in southern Africa.

The methods involve soil fertility management as well as reduced tillage. Tilling is breaking up and turning the soil to prepare the ground for planting.

They say one way to renew the soil is to use a plant called mucuna. Mucuna is a herbaceous vegetable. Its seeds can be planted during the short rainy season. Then the land is free to be planted with sorghum during the best growing season.
