Two ways to reduce wind erosion are: Covering the Surface of the Soil and Making use of Shelterbelts.
Explanation:
Wind erosion is a natural activity where a soil is moved from one place to another mainly because of the wind power. If so happens that a strong blow of wind comes and takes away with it the volume of soil particles and transfers it to other place creating dust storms.
Wind erosion can be reduced by Covering the Surface of the Soil. This can be done by growing vegetation which will protect the soil by the keeping the wind off the soil surface. Another way to reduce wind erosion is by making use of Field Shelterbelts. Shelterbelts are the best way because it not only reduce the wind erosion but at the same time it also conserve the soil moisture. Shelterbelts is a planting method where fields are planted in rows of varied crops.
