Eroded hilltops due to tillage erosion. Tillage erosion is a form of soil erosion occurring in cultivated fields due to the movement of soil by tillage. [1] [2] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [3] [4] [5] A signature ...
Reduced tillage [note 1] leaves between 15 and 30% crop residue cover on the soil or 500 to 1000 pounds per acre (560 to 1100 kg/ha) of small grain residue during the critical erosion period. This may involve the use of a chisel plow, field cultivators, or other implements.
In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolian) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. [1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of ...
Evaporation from tilling increases the amount of water by around 1/3 to 3/4 inches (0.85 to 1.9 cm) per pass. [64] Gully formation can cause soil erosion in some crops, such as soybeans with no-tillage, although models of other crops under no-tillage show less erosion than conventional tillage. Grass waterways can be a solution. [65]
This method is also known for preventing tillage erosion. [2] Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines ...

Different types of tillage result in varying amounts of crop residue being incorporated into the soil profile. Conventional or intensive tillage typically leaves less than 15% of crop residues on a field, reduced tillage leaves 15–30%, and conservation tillage systems leave at least 30% on the soil surface.
