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.

Contour plowing or contour farming is the farming practice of plowing and/or planting across a slope following its elevation contour lines. These contour line furrows create a water break, reducing the formation of rills and gullies during heavy precipitation and allowing more time for the water to settle into the soil. [ 1 ]
Cultivators' teeth work near the surface, usually for weed control, whereas chisel plow shanks work deep beneath the surface, breaking up the hardened layer on top. Small toothed cultivators pushed or pulled by a single person are used as garden tools for small-scale gardening, such as for the household's own use or for small market gardens .
