Plows is loosening and turning the top soil with the help of a plow. By plows the soil structure is improved. A larger, rough surface results. A loose, water-storing structure is reached by increased oxygenation, weather effects as well as decomposition of the organic materials. This is called or refines. When plowing besides roots of the preceding arable crops are cut up and possible Pflanzenreste are trained Also a plows of particularly applied fertilizer is favourable into a certain depth.

As a rule one plows square, with the turning plow or with a sufficient broad Rain (edge of field) also which is then called outline plows (amerik. contour ploughing). Particularly the arrangement of the furrows parallel to the slope, serves for it, to decrease the erosion (slope rinsing) in the Great Plains; often in connection with the cultivation of strip.

The success of plowing depends from the correct time, on that the soil adapted operating depth and on the weather. If this is not considered, the plow of the soil structure can cause to substantial damage. Normally in the autumn one plows. Large lumps of earth can disintegrate thereafter over the winter by frost breakup. Because of the soil organisms and the humus layer is not to be plowed too deep. Fields are partly smoothed also with the harrow/selvedge ("geeggt ").

There are world championships in plowing. With those above all the speed, accuracy and constant depth are judged. Many the world champion come from the Marchfeld into Lower Austria, where even its own monument was dedicated to them.
