Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. A sequel to the deforestation is typically large scale erosion, loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks and affect both erosion and fertility. When plants, especially trees, die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service.

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.
