discuss the agricultural practices that can be adopted for soil conservation in brief
Answers
Explanation:
Soil conservation is the prevention of soil loss from erosion or prevention of decreased fertility caused by acidification, over usage, salinization or other chemical soil contamination. Some methods normally adopted for soil conservation are:
Afforestation
1) Checking Overgrazing
2) Constructing Dams
3) Changing Agricultural Practices
Crop Rotation
Strip Cropping
Use of Early Maturing Varieties
Contour Ploughing
Terracing and Contour Bunding
Checking Shifting Cultivation
Ploughing the Land in Right Direction
We can save a lot of our valuable soil by bringing about certain changes in our agriculture practices.
Answer:
Following methods are normally adopted for conserving soil:
1. Afforestation:
The best way to conserve soil is to increase area under forests. Indiscriminate felling of trees should be stopped and efforts should be made to plant trees in new areas. A minimum area of forest land for the whole country that is considered healthy for soil and water conservation is between 20 to 25 per cent but it was raised to 33 per cent in the second five year plan; the proportion being 20 per cent for the plains and 60 per cent for hilly and mountainous regions.
2. Checking Overgrazing:
Overgrazing of forests and grass lands by animals, especially by goats and sheep, should be properly checked. Separate grazing grounds should be earmarked and fodder crops should be grown in larger quantities. Animals freely move about in the fields for grazing and spoil the soil by their hoofs which leads to soil erosion. This should be avoided.
3. Constructing Dams:
Much of the soil erosion by river floods can be avoided by constructing dams across the rivers. This checks the speed of water and saves soil from erosion.
4. Changing Agricultural Practices:
We can save lot of our valuable soil by bringing about certain changes in our agricultural practices. Some of the outstanding changes suggested in this context are as under:
