*     Soil Conservation


Soil conservation is the process in which we use techniques that will protect the soil from agents like wind and water. This also takes into account the methods that add to the fertility and protects the natural qualities of the soil.



*          The Technique and the Methods of Soil Conservation are


*           Afforestation

Afforestation is also known as planting of trees. This is a major check on the rate of soil erosion. Trees and grasses grown on hilly areas prevents soil erosion by water flowing down the slope.



*           Soil Cover

The farm land should be covered with grasses or dried trees and bushes after harvesting of a crop. This will ensure that the soil is not bare and wind cannot easily carry it away.

           Soil Cover  

*          Shelter Belts

Soil erosion can be reduced by reducing the speed of the wind. Hedges and small bushy trees can be grown along the edge of the farmland as wind breakers.

       Shelter Belts  


*           Crop Rotation

Crop rotation simply means rotation of planing of the crops. Different crops should be grown on the farmland one alternating the other. This gives soil the time to recoverthe minerals that earlier crop have used. It also helps to maintain the quality and fertility of the soil.

   Crop Rotation  


*         Terrace or Step Farming

Terrace or step farming is done in hills by cutting steps in the slopes. This type of farming reduces the speed of water as it flow down. As a result erosion of soil gets reduced. The soil removed from one step is deposited on the next step. This helps in further slowing down of erosion.

Terrance or step Farming  


*         Construction of Embankments

Rivers constantly remove soil of their banks. Strong embankments of rocks so that it can bind the soil or by building dams along the banks can prevent the soil erosion by flooding.

The average quarter acre lawn contains 50 to 250 earthworms.

It can take 100 to 500 years to create one-inch of soil.

Just one gram of soil contains 5000 to 7000 different species of bacteria.

The first recorded use of turquoise dates back to 5000 BC in Mesopotamia, where people used the gemstone to make beads.




Rock: Earth's crust is made up of rocks which has minerals.

Soil: The uppermost layer of the earth.

Type of rock: There are 3 different types of rocks igneous, sedimentary and metamorphic.

Layer of soil: There are four different layers of soil according to their composition.

Soil erosion: Removal of top and fertile layer of soil by natural agents like wind and water.

Soil conservation: Protection of soil from erosion..
