✔✔SOIL EROSION AND SOIL CONSERVATION ✔✔
Soil erosion is the removal of the soil cover and subsequent washing down of topsoil.
The process of soil formation and erosion go on simultaneously and generally there is a balance between the two.
Sometimes, this balance is disturbed due to human causes like deforestation, over-grazing , construction and mining, etc. It can lead to infertility of soil, desertification and flooding.
✔✔NATURAL CAUSES✔✔
=> Erosion through wind, Glacier and water are natural causes.
●● WIND EROSION ●●
==> It occurs due to wind blowing off the loose soil in the top layer, unless it is held down by binding agents like trees, bushes etc.
This can be reduced by methods of strip cropping and planting of shelter belts of trees in arid and semi-arid regions. These methods are discussed below .
● 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 the wind. This method is known as strip cropping.
● Shelter belts :- Planting rows of trees to create shelter along the edge of fields. This helps in reducing the speed of wind. Rows of the trees are called shelter belt
●● WATER EROSION ●●
==> Water flowing down over large area causes the topsoil to be washed away. This is called the SHEET EROSION . GULLY erosion occurs by water flowing down through small channels. Erosion is caused by Deep channels of water flowing down. This causes land unfit for cultivation and is known as badland. Such is the case in the Chambal basin, where the gullies are known as Ravines.
✔✔ HUMAN CAUSES ✔✔
==> Deforestation, overgrazing and faulty methods of agriculture are human actions which adds to the natural factors causing soil erosion. Soil conservation in the hilly areas of the country, soil erosion has been stopped by employing CONTOUR PLOUGHING and TERRACE FARMING.
Both methods do not allow water to run down the slopes to prevent soil erosion. Restricting the grazing of animals, planting trees on Barren hill slopes and constructing suitable dams to avoid large-scale water flow are other methods used to reduce soil erosion
