"' Erosion control "'is the practice of preventing or controlling wind or water erosion in agriculture, land development, soil loss, wildlife habitat loss and human property loss.

Steep slopes encourage rapid soil loss by erosion and allow less rainfall to enter the soil before running off and hence, little mineral deposition in lower profiles.
23.
Protection against soil loss is maximized with rotation methods that leave the greatest mass of crop stubble ( plant residue left after harvest ) on top of the soil.
24.
In fact, studies have shown that planting " Vetiveria nigritana " hedgerows reduces soil loss by around 70 %, which allows farmers to retain the nutrients within their soil.
25.
Combined with terracing on the field, it was a strategy that would keep soil loss within allowed limits, according to government formulas that predict what will happen in various conditions.
26.
As the peoples of Western Europe were encouraged by the Empire to maximise the use of land for growing crops, the area around Sutton Hoo suffered degradation and soil loss.
27.
Top soil loss takes place in alkali soils due to erosion by rain water surface flows or drainage as they form colloids ( fine mud ) in contact with water.
28.
Precise figures won't be known for days, but John Thatcher, winemaker at Cuvaison Winery on the Silverado Trail near Calistoga, said that despite appearances, there had been very little soil loss.
29.
For example, in the Great Plains, it is estimated that soil loss due to wind erosion can be as much as 6100 times greater in drought years than in wet years.
30.
"' Filtration "'is the equilibrium soil-to-geotextile interaction that allows for adequate liquid flow without soil loss, across the plane of the geotextile over a service lifetime compatible with the application under consideration.
