What can people do to slow down wind erosion?
Another effective control of wind erosion is by growing permanent vegetation cover. This involves growing grasses, vines, shrubs, and trees, or legumes to erosion-prone areas. This practice is applicable especially to regions where conservation of soil is challenged.
Why is wind considered an agent of erosion?
Wind causes erosion of rock particles driven by soil and sand particles that are not tightly glued together and not insulated by vegetation. The carrying away of dry soil and loose sand particles is known as deflation. The action of wind continues until that time when the power and momentum of wind cannot move the loose particles.
How can humans reduce 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 can wind erosion directly affect human activities?
Wind erosion damages: human health as airborne dust can cause asthma and other health problems. agricultural production by stripping away the fertile top layers of the soil and organic matter. the environment when dust chokes creeks and deposits unwanted nutrients and salt, threatening plants and animals and causing blue green algal blooms
What are two ways does the wind cause erosion?
Wind erosion uses two main mechanics: abrasion and deflation . Deflation is further broken down into three categories: surface creep, saltation and suspension. The wind carries tiny particles along with it when it blows. When the wind blows against solid objects, those particles strike the objects.
What can slow wind erosion down?
Vegetation can slow the impact of erosion. Plant roots adhere to soil and rock particles, preventing their transport during rainfall or wind events. Trees, shrub s, and other plants can even limit the impact of mass wasting events such as landslides and other natural hazards such as hurricanes.
What occurs during a wind erosion?
Wind erosion damages the soil by physically removing the most fertile part, lowering water-holding capacity, degrading soil structure, and increasing soil variability across a field, resulting in reduced crop production. It tends to remove silts and clays making the soils sandier. It also causes plant damage from abrasion, blowouts, and deposition.
