Soil erosion is a process of detachment and transportation of soil by natural agencies of water and wind. Factors Influencing Soil Erosion: There are many factors which influence the process of soil erosion; these are discussed below: 1. Rainfall: Precipitation is the most forceful factor causing erosion.
Prevention of Soil Erosion There are ways to avoid and manage soil erosion. One of the best ways to prevent soil erosion is to increase vegetation.Soil erosion reduces soil productivity by physical loss of topsoil, reduction in rooting depth and loss of water. In contrast soil, soil depletion means loss or decline of soil fertility due to crop removal or removal of nutrients by eluviations from water passing through the soil profile (Lal, 1990).Soil erosion and its prevention: Soil erosion by water, wind and tillage affects both agriculture and the natural environment. Soil loss, and its associated impacts, is one of the most important (yet probably the least well-known) of today's environmental problems.

Due to soil erosion, the soil becomes less fertile. The top layer of soil is very light which is easily carried away by wind and water. The removal of topsoil by the natural forces is known as soil erosion. Causes of Soil Erosion. Various agents, like wind, water, deforestation, overgrazing by cattle, etc., cause soil erosion. The various.

Soil is the most fundamental and basic natural resource for all life to survive. Water and wind erosion are two main agents that degrade soils. Runoff washes away the soil particles from sloping.
Soil erosion is a major driver of desertification. It gradually transforms a habitable land and the ASAL regions into deserts. The transformations are worsened by the destructive use of the land and deforestation that leaves the soil naked and open to erosion.
Improvement in agricultural production, rather than mitigating soil erosion, is of more significance and desirable for the farmer, while prevention of soil loss is an “unreal concept” for them (Hudson, 1987). The new approach of soil conservation will be a mixture of both agronomy measures as well as mechanical works ( Tracy, 1988).
Soil erosion is the displacement of the upper layer of soil, it is one 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.
Soil pollution: Causes, effects and control.. also lead to erosion of soil. Types of soil. pollution can be distinguished by the. source of the contaminant a nd its effects of.
Erosion by Water. Rainfall Intensity and Runoff: The impact of raindrops will break up the soil and water build-up will create runoff, taking sediment with it. Soil Erodability: Based on the characteristics of each unique soil, it is more or less susceptible to erosion. Recurring erosion is more typical for soil in areas that have experienced erosion in the past.

Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.
Ways to Prevent Soil Erosion Soil Erosion Although many areas on earth can sustain plant growth, only about eight percent of the earth’s surface is covered with good topsoil. While it takes nature hundreds of years to make a few centimeters of topsoil, erosion can easily remove it.
Some other measures to control soil erosion are: construction of check dams, ban on shifting cultivation, controlled grazing, afforestation, mixed cropping and mixed farming etc. Planting species of plants that can restore the ecological balance of an eroded area is also necessary as rehabilitation of the damaged soil is as much important as its prevention from getting eroded.
Soil erosion is the movement and transport of soil by various agents, particularly water, wind, and mass movement; hence climate is a key factor. It has been recognized as a major problem since the 1930s and, although there has been some 70 years of research into the causes and processes, it is still increasing and of growing concern. Global.
