Question

How can we prevent soil erosion ?

Answer 1

Hint:
 Soil erosion is a concern not only for its effects on plant growth but also for its effects on water quality. Soil is a valuable natural resource that nurtures and supports plant growth, among many other things. When the soil is left bare and exposed, air and water can wipe it out.

Complete answer:
Sediments carried to the drains and surface water runoff can increase aquatic life and raise water temperatures. Various pollutants such as bacteria, nutrients and heavy metals can also be associated with these sediments, which can lead to deterioration in water quality.

Soil erosion is gradually worn away from the soil surface, which removes organic materials and key nutrients in the process. If it continues uncontrolled, erosion can reduce soil quality and reduce root depth, reducing crop yields. Sediment and nutrients removed from water erosion can kill fish and affect water quality, and wind erosion can cause safety hazards from blowing dust.

Factors of soil erosion:
- Air - Also known as "soil drifting", wind erosion is the removal, transport, and deposition of toposils by high air velocities close to the ground. Wind erosion is most often a problem on flat land and in dry climates.

- Till- Tillage lage erosion occurs when tiling activity degrades the soil. The extent of erosion varies depending on the range of slope and the depth and speed of tillage.

Prevention of soil erosion -

- Crop rotation: Rotting in high-residue crops - such as corn, hay, and small grains - can reduce erosion because the layer of residue protects toposil from being carried away by wind and water.

- Conservation tillage: Traditional tillage creates a smooth surface that is prone to soil erosion. Conservation tillage methods such as without tillage, strip rotary tillage, chisel, and discharging leave more of the surface of the area covered with crop residue which protects the soil from erosive forces.

- Contour Farming: Planting in a row pattern that runs level around a hill - rather than up and down the slope - has been shown to reduce runoff and reduce the risk of water erosion.

- Strip farming: In areas where the slope is particularly steep or there is no alternative way to prevent erosion, planting fields in long strips alternatively in the crop rotation system (strip farming) has proved to be effective.

- Terrace farming: Many farmers have successfully done erosion by planting in flat areas created on hills in step-by-step formation (roof).

Note:
Your soil is one of the most important assets of your farming or wrenching operation, and losing it through erosion can seriously affect your bottom line. The time, effort and resources you spend today on erosion prevention is a valuable investment in the future of your business.
