Soil Erosion and The Erosion of Civilizations

Soil erosion began at the dawn of agriculture as people abandoned the lifestyle of hunter gathering and began to utilize the land for intensive agriculture. For many civilizations, cleaning and erosion of the surface are considered not to attract attention, even if it is too late, as the main cause of death. For thousands of years, cultivated land has been destroyed by soil erosion and other degradation processes.

"Soil erosion is a form of soil degradation Soil erosion is a natural process in all lands Soil erosion is the cause of soil erosion is water and wind and cause a lot of soil loss every year Soil erosion is relatively noticed Loss of soil from agricultural land may be reflected in lowering the possibility of crop production, lowering the quality of surface water quality, and damaging the drainage network.

Soil erosion is the movement of soil particles by natural processes such as wind and water. In a peaceful soil with natural vegetation, soil erosion usually occurs very slowly. Erosion and deterioration of soil are problematic only when the soil is cultivated for cultivation or strong grazing. In cultivated land, due to the erosion of the land, topsoil rich in nutrients is generated, the total harvest amount decreases (in case of serious wind erosion), and sediment may deposit on roads and waterways. Soil runoff from nutrients, organic matter, pesticides also affects water quality and habitat. Soil erosion in the UK is not as serious as in other countries, but it is a serious problem due to more extreme weather phenomena. All farms in England currently receiving a single payment must undergo soil protection assessment as part of mutual compliance

What is soil erosion Erosion can be defined as removal of soil particles by wind and water movement. Soil erosion is considered one of the main concerns of today's world agriculture. Land abuse, poor management of agricultural land, deforestation, overgrazing, poor management of soil and water resources are all habits leading to soil erosion. Erosion can lead to soil fertility, water supply, crop yields. - ... Therefore the shear strength measured in water content is equal to the liquid limit and the 30 ° and 60 ° apex cone is rounded to 1 point after the decimal point giving the same shear strength value of 1.7 kN / m 2 It will be. Further work by Moon and White (1985) compared LL test results of 30 samples using drop corn 30 ° apex angle, Casagrande 4 point method and one point method.
