Answers
Answer:
1. 1. Gardening
Planting vegetation and grass can stop heavy rains from damaging our land and it protects the topsoil from being washed away.
2. Afforestation and Reforestation
Planting trees can prevent flooding which causes soil movement and erosion.
3. Conservation Tillage
Avoid stripping a whole field uncovered because it can cause harmful effect on the soil. Leaving a few vegetation or grass can keep the soil at bay.
4. Constructing Wind Breakers
Fences, bushes, hedges and trees can prevent gusty winds from damaging our soil.
5. Using Fertilizers
Applying fertilizers and compost can make the soil healthy and more resistant to soil erosion.
2.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.
Strip Farming: In areas where a slope is particularly steep or there is no alternative method of preventing erosion, planting fields in long strips alternated in a crop rotation system (strip farming) has proven effective.
Terrace Farming: Many farmers have successfully combated erosion by planting in flat areas created on hillsides in a step-like formation (terrace farming).
Grass Waterways: By planting grass in areas of concentrated water flow, farmers can prevent much of the soil erosion that results from runoff, as the grass stabilizes the soil while still providing an outlet for drainage.
Diversion Structures: Used often for gully control, diversion structures cause water to flow along a desired path and away from areas at high risk for erosion.
