Therefore, in these regions, the phrase "plowing, disking, and harrowing" refers to three separate tillage steps. This is not any official distinction but is how farmers tend to speak. It is also common, at least in the United States, to consider disc plows to be a separate class of implement from discs (disc harrows).
Soon after 1900, the farm tractor was introduced, which made modern large-scale agriculture possible. However, the destruction of the prairie grasses and tillage of the fertile topsoil of the American Midwest caused the Dust Bowl , in which the soil was blown away and stirred up into dust storms that blackened the sky.
In agriculture, a harrow is a farm implement used for surface tillage. It is used after ploughing for breaking up and smoothing out the surface of the soil. The purpose of harrowing is to break up clods and to provide a soil structure, called tilth, that is suitable for planting seeds.

The University of Arkansas Division of Agriculture (U.A.D.A.) suggests different amounts of Nitrogen addition to soil depending on such factors as soil type, rice variety being grown, crop rotation, etc. For example, the U.A.D.A. recommends 150 lb. N/acre ("this recommendation is for N applied in a 2 or 3-way split application where 90 lb N ...
Strip tillage has some similarities with no-till systems because the surface is protected with residue. However, strip-till also has a similar effect on soil properties as conventional tillage systems because the farmer still breaks the soil's crust which allows aerobic conditions to speed the decay of organic matter.
