Question

What are the methods to control soil erosion?

Answer 1

Hint: Trees and grass can be of great help to prevent soil erosion.
They hold the soil tight enough that the flowing water does not strip the ground off of the topsoil.

Complete answer: Soil erosion is the gradual removal of the top layer of soil, which causes loss of organic matter and nutrients in the process. If it continues unchecked, there is degradation in soil quality and decrease in rooting depth, thereby reducing crop yields.
1. In order to control soil erosion, first of all, we need to study the causes of soil erosion so that we are able to access the situation in a better way.
2. Causes of soil erosion include: Wind, Water, and Tillage
3. Here are some basic ways to control soil erosion:
a. Crop rotation – This would prevent the removal of the top layer of soil by keeping the soil tightly bound within the plant roots.
b. Conservation tillage – The conventional tillage generally leaves a smooth top surface that makes the top layer vulnerable to erosion. Instead, methods like strip – rotary tillage can be employed to avoid soil erosion.
c. Contour farming, Strip farming, Terrace farming, Grass waterways are other methods in use. Diversion structures can be made so that the water flows only along the desired path and not anywhere else.

Note: In order to prevent soil erosion, individual efforts like planting shrubs wherever there is an empty area can be of great help to control soil erosion.
