Explanation:
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil.There are various methods for soil conservation such as afforestation, manuring and crop rotation, step farming, windbreaks, strip cropping, mulching. Strip cropping is the method of farming in which the field is partitioned into long, narrow strips which are alternated in a crop rotation system
Answer:
1) Mulching - The bare ground between plants is covered with a layer of organic matter like straw.it helps to retain soil moisture.
2)Contour barriers - Stones,grass,& soil are used to build barriers along contours.Trenches are made in front of the barriers to collect water.
3)Rock dams - Rocks are piled up to show down the flow of water.This prevent gullies & further soil loss.
4)Intercropping - Different crops are grown in alternate rows & are sown at different times to protect the soil from rain wash.
5)Shelter belts - In the coastal & dry regions, rows of trees are planted to check the wind movement to protect soil cover.
