Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the loss of fertility.
1. Implement Good Drainage Systems
Proper drainage such as trenches, raised bunds can help channel excess water away from crops and prevent soil erosion.
2. Cover Crops
Planting cover crops (secondary species) like cowpea between rows of cash crops is one way of promoting soil conservation.
3. Strip Cropping
In this, farmers combine high-growing crops with low-growing ones for the sake of protection from heavy rains, like when corn grows in strips with forage crops.
4. Mulching
A mulch is a layer of material applied to the surface of soil. Mulching prevents runoff and the formation of hard crust after each rain.
5. Contour Farming
Contour farming involves ploughing, planting and weeding along the contour, i.e, across the slope rather than up and down.
