What did Jethro Tull's seed drill accomplish?

Jethro Tull's seed drill was a significant agricultural innovation during the Agricultural Revolution, specifically designed to efficiently plant seeds in rows at the correct depth and spacing. This invention allowed for more uniform distribution of seeds, ensuring that each seed had the opportunity to germinate and grow, thus increasing overall crop yields. By placing seeds in rows rather than broadcasting them over the ground, the seed drill minimized waste and improved the efficiency of planting. This method also facilitated better soil management and cultivation between the rows of crops, which contributed further to agricultural productivity.

Other options do not accurately describe the purpose of the seed drill. For instance, the seed drill did not produce fertilizers, mechanize harvesting, or dig irrigation canals. Its primary function concentrating on the planting of seeds marked a pivotal improvement in agricultural practices during the period, contributing to the success of larger scale farming necessary to support the growing population during the Industrial Revolution.
