Rills can often be found in between rows of crops. Gullies are larger than rills and cannot be fixed by tillage. Gully erosion is an advanced stage of rill erosion just as rill is often the result of sheet erosion. Tillage practices are used for wind erosion control by producing a rough, cloddy surface that maintains surface residue and conserves soil moisture. When used along with crop residues, also known as stubble mulch tillage, reduced tillage, or conservation tillage, it reduces wind velocity and traps eroding soil.
Tillage is also very effective in controlling rill and sheet erosion.
The rough surface along with crop residues stops rainwater from carrying of soil particles and other organic matter. There are several accepted Best Management Practices that are used frequently in controlling erosion factors of both wind and water. They range from better utilization of the natural environment to construction of artificial devices, but all can be effective in minimizing potential damage. Crop rotation, Contour Cultivation, Strip-Cropping, Terraces, Grass Waterways, Diversion structures, Drop Structures, Riparian Strips, and Conservation Tillage. Erosion control can become a very economically involve process.
