Scientist of the Day - Jethro Tull
Jethro Tull, an English agricultural reformer, was baptized Mar. 30, 1674. Tull has traditionally been hailed as a key figure in the launching of the English agricultural revolution; in fact, in older literature, it is often said that the revolution began with the publication of Tull's book, The Horse-hoeing Industry (1731). Tull invented a horse-drawn seed drill (second image above) that allowed crops to be planted in rows, so they could be more easily weeded, and this is said to have been a key element in the mechanization of agriculture. However, it has been recently argued that the agricultural revolution owed little to farm machinery, being more the result of land enclosure, the institution of a four-crop rotation system, and the development of selective animal breeding. Tull lobbied against crop rotation, was opposed to letting fields lie fallow or be planted with clover to recover their fertility, and camp

Jethro Tull (1674 - 1741)
Jethro Tull ©Tull was an agricultural pioneer and the uppfinnare of the seed drill, a major development in the agricultural revolution.
Jethro Tull was born in 1674 into a family of Berkshire gentry. He studied at Oxford University and Gray's Inn in preparation for a legal and political career, but ill health postponed these plans and, after his marriage in 1699, he began farming with his father.
At the time, seeds were distributed into furrows ('drilling') by grabb. Tull had noticed that traditional heavy sowing densities were not very efficient, so he instructed his staff to drill at very precise, low densities. By 1701, his frustration with their lack of cooperation prompted him to invent a machine to do the work for him. He designed his drill with a rotating cylinder. Grooves were cut into the cylinder to allow seed to resehandling from the hopper above to a funnel below. They were then directed into a channel dug by a plough at the front of the machine
