explain the method for soil conversation Related:  NCERT Solution- Resources and Development?

Answer

*Methods of soil conservation:

*Contour ploughing: Ploughing along the contour lines can check the flow of water down the slopes. It is called contour ploughing. It can be practised on the hills.

*Terrace cultivation: Steps can be cut out on the slopes making terraces. It restricts soil erosion. It is practiced in western and central Himalayas.

*Strip cropping: Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of wind. This method is called strip cropping.

*Planting of shelter belts: Planting lines of trees to create shelter also checks the soil erosion. Rows of such trees are called Shelter Belts. These shelter belts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India.

Answer

Contour mowing.
Terrace farming.
Windbreaks.
Cover crops/crop rotation.
Soil-conservation farming.
Salinity management.

Answer

(i) Contour farming->
In such areas the ram water is absorbed in very little amount because of its quick downward movement on the slopes

(ii) Tillage and keeping the land fallow->
There are several diverse opinions as to whether deep ploughing gives good result or shallow ploughing.

(iii) Crop rotation, sowing of leguminous crops and mixed cropping->
Mixed cropping is another important method for increasing productivity of the soil.

(iv) Mulching->
It means covering the soil surface by straw, leaves or grasses. Mulches of different kinds check soil erosion, increase soil fertility and also minimize moisture evaporation from the top soils.

Answer

Various methods for soil conservation are :

1. afforestation, it is a process of planting more trees and seeds on land it reduces the surface runoff and binds the soil.

2. Rows of trees or shelterbelts are planted in desert regions to protect the fields from wind erosion.

3. Overgrazing by animals like sheep and goats must be checked. fodder crops should be raised. the free movement of animals in the fields should be restricted.

4. Steps should be taken to check reckless cutting of trees.

5. Floods should be avoided by building dams across the rivers.

6. Terrace farming and contour ploughing should be encouraged across the hill slope.

7. Scientific agriculture practices like rotation of crops, strip cropping, etc should be systematically followed.

Answer

Method for Soil Conservation

Soil conservation is the practice of protecting the soil from erosion, degradation, and depletion. It is necessary to maintain the fertility of the soil and prevent the loss of valuable nutrients. There are several methods for soil conservation, which are discussed below:

1. Contour Farming
Contour farming is a method of soil conservation in which the land is plowed and planted around the contour of the slope. This helps to prevent soil erosion by slowing down the flow of water and holding the soil in place.

2. Terrace Farming
Terrace farming is a method of soil conservation in which the land is plowed and planted on a series of terraces. This helps to prevent soil erosion by slowing down the flow of water and holding the soil in place.

3. Strip Cropping
Strip cropping is a method of soil conservation in which different crops are grown in alternating strips. This helps to prevent soil erosion by holding the soil in place and reducing the amount of water that runs off the land.

4. Crop Rotation
Crop rotation is a method of soil conservation in which different crops are grown in a specific order. This helps to prevent soil depletion by allowing the soil to recover and replenish the nutrients that were used by the previous crop.

5. Mulching
Mulching is a method of soil conservation in which a layer of organic material is spread on the soil surface. This helps to prevent soil erosion by holding the soil in place and reducing the amount of water that runs off the land.

6. Conservation Tillage
Conservation tillage is a method of soil conservation in which the land is plowed and planted without disturbing the soil. This helps to prevent soil erosion by leaving the soil in place and reducing the amount of water that runs off the land.

Conclusion
Soil conservation is essential to maintain the fertility of the soil and prevent the loss of valuable nutrients. There are several methods for soil conservation, including contour farming, terrace farming, strip cropping, crop rotation, mulching, and conservation tillage. By implementing these methods, we can protect our soil from erosion, degradation, and depletion.
