Q: I lose a lot of top soil every rainy season. What can I do to stop this?
A: True, heavy rains wash away the top soil. With the erosion, a lot of the fertility is swept away. This leaves the farm with deep gullies.

Use strong grasses such as napier (ebisagazzi) or Guatamela grass. You can also use contours or ridges to control soil erosion. These also increase water infiltration in the soils.
