There are several ways to prevent erosion, including grassing waterways, conserving tillage, covering crops, managing pastures and fortifying stream and riverbanks. Some erosion control methods, such as fortifying embankments along waterways, take place at the source, while others, such as modifying farming techniques, occur offsite. These techniques help to control and stabilize erosion on short- and long-term bases and are ideally used in combination.Know More
One common method of controlling erosion involves placing filter strips and buffers along river corridors and slopes. These strips help to slow water speed, trap sediment and debris and filter harmful toxins and pollutants, such as chemicals and pesticides. These strips prevent sediment from leaving farm areas and infiltrating nearby water systems. Grassing waterways is another erosion control mechanism that reduces the volume of tillage and reduces soil loss.
Contour farming is a long-term method of erosion prevention that creates perpendicular rows along valleys and crop fields instead of perpendicular rows that run vertically up and down slopes. These crop rows create series of small dams that slow water flow and reduce soil loss. Pasture management is another long-term technique that involves appropriately balancing the number of grazing animals with the size of farm land, which allows water-absorbing vegetation to grow and prevents plants from being uprooted, which in turn reserves critical cover.Learn More
Erosion is a natural process in which rocks or soil are moved from one location to another by wind or water. Material may move through erosion for distances ranging from a few feet to thousands of miles. Erosion often is most noticeable along shorelines, but it occurs in a variety of areas throughout the world.Full Answer >
Wind erosion happens when pieces of the Earth are worn away by strong winds over time, and water erosion happens when moving water such as ocean waves wear away rock instead of seeping into the ground. Water is a more powerful erosion force than wind.Full Answer >
Erosion is a process that causes the soil surface to wear out; geological erosion is caused naturally by water, wind or gravity, and accelerated erosion is caused by human use of land. Geologists estimate that 70 percent of soil erosion is caused by human activities like excessive construction, agriculture, surface mining and forestry.Full Answer >
By definition, wind erosion involves the erosion, transportation and deposition of soil by the wind, according to Dictionary.com. Wind erosion is often worse during dust storms. Poor farming practices by humans combined with drought conditions such as occurred during the 1930s in the United States increase wind erosion.Full Answer >
