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 about 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 >
There are four principal contributors to acidic soil: rainfall and leaching, the decomposition of organic materials, the introduction of high-acidity materials into the soil and the harvest of abundantly yielding crops. The more time that passes, the more likely a soil becomes acidic and the less easily plants grow. One way the acidity of soil can be neutralized is to add lime to the soil.Full Answer >
The white material in commercial potting soil is perlite or vermiculite, substances that retain water and add texture to the soil to keep it from becoming compacted. Most commercial potting soil mixtures are made up of at least 25 percent perlite.Full Answer >
