How much soil is carried away depends on how strong the rain or wind is as well as the soil quality, topography (for example, sloped versus terraced land), and the amount of ground vegetation. Healthy topsoil (like soil covered with plants) is less erodible. Topsoil, which lies adjacent to the plane of the land, withholds vital nutrients for the crops to fertilize. But some plants can adhere to the cause of erosion like coffee, soybean, palm oil, cotton, and wheat can increase soil’s PH level due to the use of fertilizer affecting the soil’s capacity to retain itself.

Soil erosion, or the gradual reduction of topsoil in a geographic area, can be caused by both natural and unnatural processes, but it can also have great effects on inhabitants of an affected area. One of the major concerns regarding soil erosion is that it can permanently affect the land, which can be devastating for farmers or those with agricultural pursuits. Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation.This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans. 2021-04-11 · Half of the topsoil on the planet has been lost in the last 150 years. In addition to erosion, soil quality is affected by other aspects of agriculture. These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity.

Topsoil, which lies adjacent to the plane of the land, withholds vital nutrients for the crops to fertilize. But some plants can adhere to the cause of erosion like coffee, soybean, palm oil, cotton, and wheat can increase soil’s PH level due to the use of fertilizer affecting the soil’s capacity to retain itself. Also known as “soil drifting,” wind erosion is the removal, transportation, and deposition of topsoil by high air velocity close to the ground. Wind erosion is most often a problem on flat land and in drier climates. Water.
