What are some practices currently to prevent wind erosion?
How to reduce wind erosion
- Reduce the number of tillage passes and intensity.
- Add a cover crop after a short-season crop.
- Leave residue standing.
- Plant vegetative buffer strips in erosive areas to trap sediment and slow wind speeds.
What are two conservation practices that help prevent wind erosion?
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.
How is wind erosion measured?
One of the most common methods to measure wind erosion in field studies are sets of passive BSNE or MWAC traps to measure the horizontal soil transport at different heights (Fig. 4). Generally, more than 3 traps are arranged vertically at a pole between heights of about 0.05–2.0 m.

Which is the best way to reduce wind erosion?
Reducing Wind Erosion 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.
How is wind erosion a threat to agriculture?
Wind Erosion can be a threat to agriculture productivity and the sustainability of the earth’s natural resources. The erosion of surface soil by wind renders the soil less productive by removing the most fertile part of the soil, namely, the clays and organic matter.
What to do about wind erosion in Nebraska?
While many producers practice no-till in Nebraska, those who run residue movers on their planters risk wind erosion problems because they detach their residues. Likewise, stalk shredding and vertical tillage increase the chance of wind erosion problems as these operations also detach crop residues.
What can be done to keep the wind off the soil?
Windbreaks and other barriers are also effective at keeping the wind off the soil surface and reducing soil particle detachment, but these practices may take land out of crop production. Once soil particles are detached, their movement needs to be limited by increasing deposition.
