What is soil erosion? Soil erosion is a natural process‚ occurring over geological time‚ and indeed it is a process that is essential for soil formation in the first place. With respect to soil degradation‚ most concerns about erosion are related to accelerated erosion‚ where the natural rate has been significantly increased mostly by human activity. Soil erosion by water is a widespread problem throughout Europe. Soil is naturally removed by the action of water or wind: such ’background’

While the nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation. Besides‚ failure of rains‚ floods‚ depopulation and loss of cattle caused by famine and pestilence‚ disturbance caused by war and interference with or change

Soil Erosion Erosion is a natural process by which rock and soil are broken loose from the earth’s surface at one location and moved to another. Soil erosion forms and changes land by wearing down mountains filling valleys‚ and making rivers appear and disappear. Erosion is usually a slow and gradual process that occurs over the course of thousands or millions of years. However the rate of erosion can be speeded up by such human activities as mining. How erosion occurs? Ero0sion begins with

defined as soil. Soils come in an almost infinite variety of vertical structures and textures. Most soils are hundreds of years old and change very slowly. The work ability of the soil is the ease in which a soil can be cultivated and is determined by the soil texture. There are distinct layers of soil that are not always visible to eye but are made up of different horizons. O horizon/Humus is the decomposing plant matter. A Horizon/Topsoil is the mixed humus and leached mineral soil. E Horizon/

How to Prevent Soil Erosion TERRACING Terrace farming is a farming method that makes use of a hill to create a multiplatform farm. There are severals steps known as andenes which are built into the side of a hill. The idea behind it is that any rain that falls and builds up on the andenes will overflow into another andene below‚ making the most out of the nutrients it provides. CROP ROTATION The successive planting of different crops on the same land to improve soil fertility and help

Soil Erosion And Conservation SOIL EROSION AND CONSERVATION Erosion Erosion is the removal of soil particles by the motion of wind or water. Soil erosion is one of the major concerns of modern agriculture throughout the world. The fallowing contributes to soil erosion: Misuse of land‚ Mismanagement of arable land‚ Indiscriminate felling of trees‚ Overgrazing‚ Poor soil and water management Erosion causes or Results in a: Decline in soil fertility‚ Water supply‚
