Seed drill

A seed drill is a sowing device that positions seeds in the soil and then covers them. The seed drill sows the seeds at equal distances and proper depth. This ensures that the seeds also get covered with soil. This saves them from being eaten by birds. Before the introduction of the seed drill, the common practice was to plant seeds by hand. Besides being wasteful, planting was very imprecise and led to a poor distribution of seeds, leading to low productivity. Jethro Tull is widely thought of as having invented the seed drill, though earlier the Sumerians used a single-tube seed drill, and the Chinese had also used a multi-tube seed drill. The use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times. In short, the seed drill can be described as a modern agricultural implement used for sowing seeds.
