Question

Mention the types of soil erosion and measures to prevent soil erosion.

Answer 1

Wind. Also known as “soil drifting,” wind erosion is the removal, transportation, and deposition of topsoil by high air velocity close to the ground.
Water. Soil can also be carried away by rain or irrigation water.
Tillage.
TO PREVENT SOIL EROSION

Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water.

Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion. Conservation tillage methods such as no-till planting, strip rotary tillage, chiseling, and disking leave more of the field surface covered with crop residue that protects the soil from eroding forces.

Contour Farming: Planting in row patterns that run level around a hill — instead of up and down the slope — has been shown to reduce runoff and decrease the risk of water erosion.

Answer 2

Types of Soil Erosion 
There are three main types of soil erosion.
Wind erosion: Wind erosion is the removal soil particles by the force and kinetic energy of the wind. These soil particles are transported and deposited when the wind energy drops.
Water erosion: Water erosion is caused by the kinetic energy of rain falling on the soil surface and by the mechanical force of runoff.
Gravity erosion: Mass movement of soil occurs on steep slopes under the influence of gravity. The process involves the transfer of slope-forming materials from higher to lower grounds due to self weight.

The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls. Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-affects of forest fire.
Vegetation: The simplest and most natural way to prevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soil and prevents soil erosion.
Geotextiles: Using geotextiles is an effective method because it also stabilizes soil. When used in conjunction with growing vegetation, it is even more effective.
Retaining Walls: Retaining walls can be built around the area of erosion to prevent water run off. Runoff water leads to further erosion, and if used with other methods, retaining walls can be a very effective way to prevent soil erosion.
