What are the soil conservation methods?

Mulching - Mulching aids in the retention of moisture in the soil. Mulching is the practise of covering undeveloped area with organic debris such as straw.

Contour Barriers — Contour barriers aid in the prevention of rain-induced erosion. Stone, grass, or dirt connected to the contour forms the contour barrier. To store water, a trench has been dug in front of the dam.

Dams, such as rock dams, can impede the flow of water. As a result, rocks are arranged to create a dam. Dams like these impede water flow. As a result, dirt and soil are not lost.

Terrace Cultivation: In steep places, terrace cultivation is utilised to decrease erosion caused by water flow. To maintain a flat surface for growing crops, the plots are built in terrace designs.

Intercropping: In this method, different crops are planted alternately. Crops mature at various periods. It aids in the prevention of rain-induced erosion.

Contour ploughing is a type of ploughing that is done parallel to the hill slope's outline. It aids in the formation of a natural barrier that keeps water from flowing down a hill.

Shelterbelt: In coastal and dry areas, this strategy is applied. Trees are placed along the field's edge. It aids in the prevention of soil erosion.
