how to conserve land resources
Answers
Answer:
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.
Growing population and there ever growing demand has led to a large scale destruction of forest cover and arable land and has created a fear of lodging this natural resource. therefore the present rate of degradation of soil must be checked.afforestation land reclamation regulated use of chemical pesticides and fertilizers and check on overgrazing or some of the common methods used to conserve land resources.
