Soil erosion negatively affects the environment by stunting the new growth of plant life due to removal of topsoil. Erosion greatly reduces the quality of the soil.Know More
Soil erosion is caused by rain, improper farming techniques and wind. When erosion occurs in soil, it typically involves the removal of the top layer. This layer is the topsoil and contains many nutrients essential to supporting plant life. When the topsoil is removed, the quality of the soil is reduced. This results in less plant life growing in the affected area. Plants bind soil together with their roots, and if they are unable to grow in the soil, erosion may be accelerated. Soil erosion can lead to the destruction of animal habitats, forcing them to relocate. Water causes soil erosion by carrying off topsoil during rainfall and dispersing it in the surrounding region.
Improper tillage practices can lead to accelerated soil erosion. If the local plant life is disturbed or removed in high quantities, erosion may occur with little resistance. Cross-slope tillage should be practiced in place of up-and-down-slope tillage because it reduces the effects of erosion. Proper crop rotation provides healthy plant growth in the soil and reduces the effect that wind and rain may have on the soil. Without healthy farming practices focused on the soil, the crops' growth and yield may be negatively affected by erosion.Learn more in Soil
Wind, water, ice and waves carry off soil particles and cause soil erosion. Although this is a natural process, human activities that disturb the surface of the earth increase the rate of soil erosion. Activities such as mining, construction, deforestation and intensive agriculture leave the topsoil exposed and vulnerable to the agents of erosion.Full Answer >
Wind causes erosion in one of three ways: suspension, saltation or surface creep. There are many problems that arise from wind erosion, including air pollution, soil loss and dryness. Soil tillage, crop barriers and crop strips all help reduce the effects of wind erosion.Full Answer >
According to Colorado State University Extension, soil texture is defined by the size of the particles that make up the soil. Soil texture typically is categorized into three types: sand, silt and clayey.Full Answer >
According to the non-profit project Coral Science, coral reefs are not lodged in soil. The rocky substance in which they are fixed is made by the corals themselves. They live in colonies made of many polyps that build skeletons from the underside of their skin.Full Answer >
