Plough

The plough is a tool used in farming for turning the earth in which one is to plant new seeds. The plough is a development of the pick, and was initially pulled by oxen or humans, and later horses. Modern ploughs are, in industrialized countries, powered by tractors.

Ploughing has several beneficial effects. One is the reduction of weeds in the fields, another that the soil becomes more porous, easing later planting.
