Three Major Causes of Soil Erosion and How They Can Be Corrected

The implications for future government planning for land degradation include the Soil erosion policy and notices and the contaminated land policy.

Erosion is a process where natural forces like water, wind, ice, and gravity wear away rocks and soil. Erosion occurs at the Earth’s surface, and has no effect on the Earth’s mantle and core. Water erosion is the removal of soil particles by heavy rainfall or running water. “While the causes of erosion by water are generally natural, water erosion is usually caused by rainfall and runoff on a slope” (GEI Works Erosion Pollution). “The process of water erosion usually occurs on stream and river banks, sea shores and seaside cliffs” (Reference.com).

At Nudgee Beach, erosion was found to have occurred on the edges of the mangrove forest and along the mudflat shorelines. Erosion is typically influenced by natural factors and occurs when pieces of weathered rock or soil are moved – typically by wind and water – from one place to another. Shorelines with lots of sediment and sand are more inclined to be effected by erosional progression. Erosion may also be provoked and accelerated by human interference. For example, if the decision to clear trees and plants from an area is made, erosion is likely to occur as the root systems of plants work to hold the soil in place. If these root systems are removed and erosion does occur, environmental conditions – such as; landslides and flooding – are more likely to take place. Erosion may also cause other plants to tip over, have their underground roots exposed and damaged and contribute to the pollution of local waters; as a result of mud and soil runoff [26]. Erosion at Nudgee Beach was likely to have been influenced by natural factors; however, the development and extension of the Kedron Brook golfing course may contribute to the acceleration of erosional processes and further damage the mangrove

Poor soil management can lead to biological, chemical, and physical degradation, which can in turn negatively alter the activity of

Soil particles such as silt, clay, and sand are known as sediments and are the most significant pollutant to come from forested areas.

Extracted soil samples indicate simultaneous reduction of rainfall and occasional erosion. Both soil and sediment features show establishment of marked

Soil Erosion - When the top layer of soil is worn down due to too much water, ice, or wind.

Erosion is a global problem, as we have already seen (umich.edu). Globally, topsoil is eroding faster than it can be replaced over 1/3 of the world's croplands (umich.edu). In the U.S, the loss of topsoil has been estimated to cost $125B per year (umich.edu). As you might imagine, this is a very difficult calculation to perform, since topsoil production rates are so slow, the lost topsoil is essentially irreplaceable (american.edu). This has been increasing within the past for years and corporations are trying to lessen the amount of erosion but it does not seem to be working

Vast numbers and kinds of organisms, mainly microorganisms, inhabit soil and depend on it for shelter, food, and water. Plants anchor themselves in soil, and from it they receive essential minerals and water. Terrestrial plants could not survive without soil, and because we depend on plants for our food, humans could not exist without soil either (Wiley, 2013).

Congress declares soil erosion “a natural menace”. Under Hugh B. Bennett, the SCS will develop programs to save the topsoil and irreparable damage to the land. New farming techniques are put in place and farmers are paid to practice soil-conserving techniques as

When we planted legumes than the soil erosion and water logging conditions will be less as compared to other crops. It is due to precipitation and runoff water level. Soil organic matter concentration increases in this way. It is the main benefit of legume to use as cover crop that reduces soil erosion and water level increases mineral content in the soil. Water up taking level of the plant also increases that helps in soil water holding capacity of

It takes up to three hundred years for one inch of agricultural topsoil to form so soil that is lost is essentially irreplaceable. The consequences for long-term crop yields have not been sufficiently measured. The amount of erosion varies from one field to another. This depends on the type of soil, the slope of the field, the drainage patterns and the crop management practices. The effects of the erosion vary also. The areas that are better able to sustain erosion without loss of productivity are areas with deep organic loams. This is more sustainable than the areas where topsoil’s are shallower.

Significantly, desertification also cause soil erosion, which means soil surface is worn by wind and water. Desertification makes soil easy to erode by water or wind, as soil is exposed and soil structure is instable without forest. LaI R(2003) says that ““Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected.” To control soil erosion, an obvious way is virescence, enlarging forest cover, which can protect the soil far from exposing to strong wind. Also, the roots of plants under ground play a role as a framework, as they are obstructions to soil movement,
