Question

List any three agronomic measures that help in soil conservation.

Answer 1

1. Cover cropping: growing grasses or legumes on fields when the main crop is absent to protect the soil surface, reduce erosion and improve fertility.
2. Contour ploughing (contour cultivation): ploughing along contour lines on slopes to slow runoff and reduce soil loss.
3. Mulching: covering soil with organic residues (straw, leaves, etc.) to retain moisture, protect the topsoil from raindrop impact and reduce erosion.
