about seed drill In 150 words
Answers
A seed drill is a sowing device that sows the seed precisely in the soil at proper depth and distance. Then it covers them with soil. It protects the seeds from birds and saves time and labour.
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.[1] The use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times.
Seed drills of earlier centuries included single-tube seed drills in Sumer and multi-tube seed drills in China, and later a seed drill by Jethro Tull that was influential in the growth of farming technology in recent centuries. Even for a century after Tull, hand sowing of grain remained common

A seed drill is a device that sows the seeds for crops by metering out the individual seeds, positioning them in the soil, and covering them to a certain average depth. ... The use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times.
Jethro Tull, an Englishman, brought about the British Agricultural Revolution in 1701 by inventing the first seed drill. Drawn by horse, the seed drill shot seeds into the ground by cutting small holes in the soil, sowing the seeds in neatly organised rows.
The Seed Drill. Jethro Tull invented the seed drill in 1701 as a way to plant more efficiently. ... A plow at the front created the row, and a harrow at the back covered the seed with soil. It was the first agricultural machine with moving parts.
Because the seed drill planted seeds in straight lines, a mechanical horse-drawn hoe, which Tull also invented, could be used to remove weeds from between the lines of crop plants. Tull advocated the importance of pulverising (crumbling) the soil so that air and moisture could reach the roots of the crop plants.
