Ja, das ist es auch, aber Bridge ist noch viel mehr. Author : Jeffrey O. The practice of turning the soil before planting is very old, but until the plow was invented, farming was limited to what humans could do by hand. The plow has enabled us to cultivate larger and larger areas of land, and in places where farming was previously impossible. Advances in plowing technology have made it possible to convert native grasslands into huge fields of corn and wheat.

Tilling the soil with a plow improves the soil in numerous ways. The plow turns over the upper layer of soil, bringing fresh nutrients to the surface. This also loosens and aerates the soil, improving its ability to hold moisture and nutrients.

Freshly turned soil is darker in color, which enhances soil warming and thereby promotes seed germination. Plowing incorporates these residues into the soil, along with any manure, limestone, and commercial fertilizers that are applied. In addition, plowing creates a pattern of low and high ridges in the soil, forming water channels that allow the soil to drain properly. The plow reduces the costs and labor requirements of agriculture.

With the introduction of animal—drawn plows, fewer people were needed to till the same amount of land. In time, mechanized plowing further reduced labor requirements, permitting the labor of a few people to sustain many. The plow greatly reduced the amount of time needed to prepare a field, consequently allowing a farmer to work a larger area of land.
