Definition of soil erosion?

Soil erosion is a naturally occurring physical process that mainly involves the removal of particles of top soil from the soil by natural physical forces such as water and wind. It affects all types of landforms.

soil erosion Soil erosion is due to any number of reasons, but especially from breakdown in surrounding conditions. Some of the major causes of soil erosion are habitat loss, excessive runoff in a given area and monoculture without rotation. This usually results in breaking and/or steepening of the ground, but it is especially noticeable in steep and sloping landscapes such as hills and mountains. I hope this should give some insight into the further nuances of erosion and its effects.

What is soil erosion?

Most of the soil nutrients, organic substances and pesticides are included in the top soil. Half of the Earth’s top soil has been lost in the last 150 years. There has been a rapid increase in soil erosion by human activities. While water erosion is a problem of hilly and sloping areas of moist areas, wind erosion is a problem of smooth and flat terrains of dry, stormy areas. The mechanism of soil erosion involves loosening and dissolution of soil particles and transport of separated soils.

There are two types of soil erosion – water erosion and wind erosion.

1. Water Erosion: The loss of soil by water is called water erosion.

  • Rain Water Erosion: Due to the direct impact of rain water droplets on the surface, the soil particles are separated and transferred which is called rain water erosion.
  • layer erosion: The erosion and separation of soil in the form of uniformly thin layers from the top soil due to rain water droplets and water flow is called layer erosion.
  • Rill Erosion: Due to heavy rains, when water starts flowing through thin drains, then the formation of less deep drains by erosion is called rill erosion.
  • Large duct erosion: Due to excessive surface water flow, deep drains are formed which are called big ducts or gullies. Such erosion is called street erosion.
  • Stream Coast Erosion: currents and rivers They keep changing their flow by cutting one edge and depositing the silt load on the other. This stream is called bank erosion.

What is the cause of soil erosion?

  • indiscriminate cutting of trees
  • vegetative dispersal event
  • forest fires
  • To induce water and wind erosion leaving the land barren/empty.
  • Growing crops that accelerate soil erosion
  • adopting a faulty crop rotation
  • To carry out agricultural work in the direction of the slope of the field.
  • adopting faulty irrigation methods

soil erosion Soil To remove the top layer of soil. There are many factors affecting soil erosion. The most common would be wind and heavy rain. Wind, rain, people driving tractors, people driving any kind of vehicle. People moving around, cattle, sheep and other animals that people keep with them to eat.

To understand soil erosion, we have to see that Soil What is lacking in Plant material plays an important role in preventing soil erosion. Thus a veld with lots of grass will have less soil erosion even if heavy wind and/or rain is present, as will soil covered with large amounts of litter (not garbage, but dead and decaying leaves and other organic matter) There will also be less erosion than bare soil. The reason for this is not only that the grass/litter covers the soil, but it also binds the soil particles, thereby avoiding excessive movement. Some of the causes of soil erosion will be climate oriented (high temperature, low temperature, rainfall, wind etc.).

Humans are the second major cause of soil erosion. Human beings are very ignorant when it comes to soil health and conservation. We love to care about everything except soil, forgetting its importance and the problems we face without it. Most of the soil erosion is due to poor management practices on farms and conservation areas/nature reserves. Some of these poor management practices will be on pastures for example. When overgrazing occurs the vegetation does not have time to recover, thus leaving the soil open for a longer period of time than when it is eroded.

In addition to all the above points, it should also be remembered that soil erosion is not necessarily bad. Soils in nature require some amount of erosion, but this should happen in a “natural” fashion, not because of poor management practices. However the answer to this question lies in much more depth than what is discussed here.

soil erosion process

When rain water droplets fall on the soil surface from a great height, they separate the fine soil particles from the soil mass. These separated soil particles are carried by the water flow to springs, streams or rivers by sliding or rolling. The erosion process includes the following steps:

  • loosening of soil particles (erosion)
  • Transportation of soil particles by various means
  • deposition of soil particles
