A seed drill is a farming tool used to plant seeds in the soil at a specific depth and spacing. This device helps ensure that seeds are sown evenly, which can lead to better crop yields. By placing seeds in rows, seed drills also make it easier to manage weeds and other plants that compete for resources. Invented by Jethro Tull in the early 18th century, seed drills revolutionized agriculture. Before their invention, seeds were often scattered by hand, leading to uneven growth. The use of seed drills has become standard practice in modern farming, contributing to more efficient and productive agricultural methods.
