Apr 13, 2024 · Soil erosion adversely impacts natural and human environments globally. Vegetation is often used as a sustainable approach to mitigate erosion. Although using vegetation to reduce erosion is a widely accepted concept, how different plant traits mitigate different mechanisms of erosion, and the generality of these mechanisms has not been well demonstrated. We developed ten hypotheses on how ...

The best way to reduce wind erosion is to keep the wind off the soil surface by covering the soil surface. Growing vegetation, either cash crops or cover crops, protects the soil and keeps the winds higher off the surface. Standing crop residues function the same way. Flattened crop residues are more effective at reducing soil erosion by water by a...
When it comes to wind erosion control, prevention is far more effective than the cure (emergency treatments once wind erosion is occurring). The soil surface should be kept covered with growing vegetation or standing, attached residues. While many producers practice no-till in Nebraska, those who run residue movers on their planters risk wind erosi...
The potential for wind erosion is reduced any time the soil surface is covered. Likewise, the potential is reduced if the soil surface is kept moist. Crop residue and growing vegetation keep the wind off the soil surface and reduce soil moisture evaporation. Tillage destroys soil cover and dries the soil and should be avoided in areas prone to wind...
Principles of Wind Erosion and its Control. A collection of minerals, organic matter, nutrients, gases, and water, soil is responsible for the production of the majority of the world’s food supply. Soil is a virtual necessity for civilizations to thrive. If it blows away, soil is not of any use. In fact, when soil enters the atmosphere, it ...

begin the erosion process. It is recommended that plowing or tilling in the fall in areas prone to erosion be avoided unless a cover crop can become established prior to the winter. Any plant residues left in the field is a benefit in controlling erosion. Residue also protects the soil from the harmful effects of raindrop impact and can reduce the
bare, and the wind velocity exceeds the threshold velocity for the soil. Al- though wind erosion may occur in humid and subhumid climates, it is more prevalent in semiarid to arid areas and is extensive in the Great Plains. In this report, we identify various practices used to reduce wind erosion and we describe their advantages and limits.

Field shelterbelts can provide extra protection against wind erosion no matter what cropping system is used. They are especially important in dry years when low crop yields result in insufficient residue cover. Field shelterbelts reduce the wind velocity for distances up to 30 times the height of the trees. They also trap
