As with coastal erosion, the effect of soil erosion on agricultural land depends on a variety of interrelated factors. The rate of wind erosion depends on the strength and direction of the wind and weight or size of the soil particles. The denudation of the soil cover and subsequent washing down is described as soil erosion. They are content to ignore it. Usually over cropping occurs in areas where there is a demand for crops either for market or a large local population. In this article, we will discuss some of the most important effects of how soil erosion negatively impacts. Industrial Activity: Industrial activity has been the biggest contributor to the problem in the last century, especially since the amount of mining and manufacturing has increased.
Causes : gravity, rain, flooding, wind, drought, deforestation, farming, flowing ice, the loss of vegetation after a major forest fire, uncontrolled land use, and poor agricultural and forestry practices Effects : desertification, additional sedimentation, loss of habitat, infertile soils, inc … reased use of soil conditioners and fertilizers, water pollution Soil erosion causes land and water pollution. Soils with less vegetation become exposed, drier and prone to further erosion by the wind and rain. Fungi and bacteria found in the soil that bind it together begin to decline, which creates an additional problem of soil erosion. The outcomes of soil erosion are reduced agricultural productivity, ecological collapse, soil degradation, and the possibility of desertification. Moreover, grazing was not an environmental issue a few years back, because people used to move from one place to another depending on the rainfall, which prevented overgrazing.
The Geochemical modeling has shown the set of mineral species that have contributed to this problem. The processes of soil formation and erosion, go on simultaneously and generally there is a balance between the two. So, this year a farmer might grow corn in his field, and next year he might grow soybeans in the same field. Streams, rivers etc, transport the fine soil particles and deposit them in lakes and reservoirs. The effects of erosion are varied, but the most obvious effect is the removal and destruction of land. Given the amount of deforestation around the world, zero net deforestation may seem unattainable.
In this project, we, the investigators, aimed to study the hydrogeological and geochemical factors that are responsible for the formation of scales by groundwater and also in creating incrustations in almost all the water supply systems borewells of Salem district, for several years. However, it is not only possible, but necessary if we intend to preserve our most precious wildlife, respect and empower local communities, maintain critical ecosystem services and reduce greenhouse gas emissions. And as land loses its fertile soil, agricultural producers move on, clear more forest and continue the cycle of soil loss. While it is important to break the strong winds it is also important to allow a certain amount of wind through this barrier as it controls the flow of the wind without creating a complete block which could result in swirling winds or strong gusts near the barrier. This type of erosion is therefore of little consequence because there is balance between the disintegration of rocks and the subsequent formation of soil. These powerful dust storms could kill exposed wildlife and aggravate respiratory problems. The report has made several scholars to follow the concept and work during the last three decades.
This is because mass movements aids in the breakdown of the soil particles that makes them venerable to water and wind erosion. Reports in recent years show erosion rates decreasing in the United States, which has invested billions in improved farmland conservation practices, said Mark Nearing, a soil scientist and erosion expert for the U. Main Causes of Soil Pollution 1. Soil moisture content and organic matter make up are some of the soil component aspects that determine erosivity of wind or rainfall. The effects of soil erosion go beyond the loss of fertile land. Plants and trees grow above the surface, protecting soil from erosion, and their roots meander down through the soil and become like bars in a prison, locking the soil particles in place, making it hard for them to escape and be carried away by water. Such a case is evident in North America where dust winds from the Gobi desert have recurrently been a serious problem.
Sediments that accumulate down slope of the erosion can obstruct the flow of water in streams and drainage canals, leading to flooding. Silt can smother the breeding grounds of fish and equally lessens their food supply since the siltation reduces the biodiversity of algal life and beneficial aquatic plants. Thus, the fertility of the soil deteriorates. Nothing can daunt him: not even the strongest tempest of adversity and the mightiest of armies. Tilling in particular, because it often breaks up and softens the structure of soil, can be a major contributor to erosion.
Erosion effects humans by adding additional toxic organic chemicals and heavy metals to the soil as well as eroding land so that there is less land to farm on. Marine crustaceans such as shrimp and crabs can also help as it was found that the shell contains a carbohydrate that proved to be excellent as a drug delivery system. The main cause of man-made erosion is agriculture, followed by construction and mining. Put simply, it is when topsoil, which is the upper-most layer of the ground, is moved from one spot to another. These areas would be clogged up with the sediment that could block drainage canals and cause flooding. Agricultural practices such as burning and clearing of vegetation also reduce the overall vegetation cover. This allows organic matter to build up, making future plantings more fertile.
Over time these stubbles decompose becoming valuable humus. It leads to deposition of silt in the water courses and in the paths through which water flows. The most susceptible soil to this type of erosion is sandy or lighter soil that can easily be transported through the air. When the top layer is removed, rills and gullies are formed in the soil. As we see, much of the effects of soil erosion are the result of water erosion. His primary fields of expertise include computers, astronomy, alternative energy sources and the environment.
However, the road ahead is quite long and the prevention of soil pollution will take many more years. When the soil has been very disturbed, weedy plant species often come in to colonize the disturbed soil. This may occur in areas of deforestation, mountain slopes or as a general practice to plant a seedling for each tree cut down. Almost all living things have compounds which are therapeutic to us, a lot of our antibiotics are derived from naturally occurring microbes, and a great deal of the medicines which are available today are made from plants, such as Digitalis. Erosion is a natural process that affects all types of land on Earth, from the grandest mountains to the humblest patches of soil.
The transformations are worsened by the destructive use of the land and deforestation that leaves the soil naked and open to erosion. Mudslides not only affect structures supported by the soil but also buildings and roads that are in the path of slides. Scientists have found that overuse of some of these chemicals changes soil composition and disrupts the balance of microorganisms in the soil. Thus, the water levels in the rivers and streams increase due to this which leads to floods. Deforestation occurs for many reasons such as the sale of wood, charcoal or as a source of fuel, while cleared land is used as for livestock, plantations of commodities, and settlements.
