A seed drill is a farming tool that helps plant seeds in a more efficient and organized way. It was invented by Jethro Tull, an English agriculturalist, in the 18th century. The seed drill allows farmers to sow seeds at a consistent depth and spacing, which improves crop yields. Before the invention of the seed drill, seeds were often sown by hand, which was time-consuming and less precise. The seed drill revolutionized agriculture by increasing efficiency and productivity, making it an important development in the history of farming.
