A plow is a farming tool used to turn and break up soil, making it easier to plant seeds. Traditionally, plows were pulled by animals like horses or oxen, but modern versions are often attached to tractors. The main purpose of a plow is to prepare the land for crops by aerating the soil and mixing in nutrients. There are different types of plows, including the moldboard plow, which lifts and flips the soil, and the chisel plow, which creates deep furrows without turning the soil completely. Each type serves specific farming needs, helping to improve crop yields and soil health.
