Question

How can we conserve land resources?

Answer 1

Soil conservation is a methodology to maintain soil fertility, prevent soil erosion and exhaustion and improve the degraded condition of the soil.

Some commonly used methods of soil conservation are:-

1. Extensive reforestation and afforestation : It is the most effective technique of checking soil erosion .

2. Prevention of faulty practices:

Prevention of over grazing, shifting cultivation, over usage of chemical fertilizers and promoting bio-fertilizers.

3. Changing Agricultural Practices:

- Crop Rotation: This refers to growing of two or more different crops in sequence in a field for maintaining the soil fertility.

- Contour Ploughing: Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.

- Terracing: On steeper slopes, terraces or flat platforms are constructed in steps in a series along the slope. This way water is retained on each terrace which can be used to raise crops. They can reduce surface run-off and soil erosion.

- Trash farming in which chopped crop residue are spread and ploughed to increase the humus and organic matter content.

4. Check dams : construction of check dams to check the flow of water and reduce it's velocity.

5.Other remedial measures: Water Management , construction of check dams, Wind Break.
