(g/kg) (LUCAS, JRC). Mullhalten Hoten mot marken Erosion (vatten). Vattenerosion  This measures the percentage (0 to 100) by weight of silt in the topsoil. Soils with a lot of silt make excellent farm land, but erode easily.

Erosion, whether it is by water, wind or tillage, involves three distinct actions – soil detachment, movement and deposition. Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil.

These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. These are very real and at times severe issues. 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.

Topsoil erosion

In this process, the soil particles are loosened or washed away in the valleys, oceans, rivers, streams or far away lands.

It is characterized by a declining groundwater table, salt accumulation in topsoil and water, a decrease in surface water, increasing erosion and the  Damage limited to the removal of performance turf and topsoil after armoring Underseepage, 11 Wave Erosion, 12 Through-Seepage and Internal Erosion,  av K Lundström · 2008 — växter, orsakade tjällossning och regn hävning och erosion i slänten. were protected by a more traditional method, crushed stones and topsoil.

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. 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.
