Explain 5 ways of land conservation
Answers
2. Contour ploughing is another measure to conserve our land. By this method, the fields are ploughed, harrowed and sown along the natural contour of the hills.
3. By terracing method: A series of wide steps are made along the slop following the contours. This method is very common in rice growing regions.
4. Under the afforestation and reforestation programmes, planting of trees, bushes and grass help to check the soil erosion,
5. Strict actions are taken to check reckless felling of trees and overgrazing.
6. Shelter belts (rows of trees) are planted on the margins of desert areas to check the fury of wind.
7. Construction of dams and gully-trap inculcate the water-harvesting.
Answer:
Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of 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, affect both erosion and fertility. When plants die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service. Farmers have practiced soil conservation for millennia. In Europe, policies such as the Common Agricultural Policy are targeting the application of best management practices such as reduced tillage, winter cover crops,[1] plant residues and grass margins in order to better address the soil conservation. Political and economic action is further required to solve the erosion problem. A simple governance hurdle concerns how we value the land and this can be changed by cultural adaptation.
