While a british rock band made his surname famous practically 300 years after his birth, Jethro Tull (1664 – 1741) to be renowned in his own right as an agricultural pioneer and the inventor that the seed drill, the horse drawn hoe, and also an improved plough, all significant developments in the 18th century agricultural revolution, a period marked by rapid breakthroughs in agricultural productivity and advancements in agriculture technology.

Tull to be born in Basildon, Berkshire, England in 1664. He studied law and graduated native Oxford university in 1699. Although he to be admitted come the bar in the very same year, he never ever practiced law. Tull began farming ~ above his father's soil in 1700 and also took good interest in agricultural processes.

At the time, farmers generally planted chop seeds by transferring the seeds in a bag and also walking up and also down the field while randomly throwing or transfer the seed by hand on come the ploughed and also harrowed ground. Tull deemed the an approach inefficient together the seed was not spread evenly and also much of it to be wasted and did not take root.

Jethro Tull"s seeds drill.

In 1701, Tull occurred a horse-drawn mechanically seed drill. The drill integrated a rotating cylinder in i m sorry grooves were reduced to enable seed to happen from a hopper over to a funnel below. The seed were climate directed into a channel dug through a till at the front of the machine, and also immediately extended by a harrow attached to the rear. Planting the seed at constant intervals, in ~ a continual depth, and in a right line minimal waste and also dramatically boosted harvest yields. According to imperial Berkshire History, Tull stated of his invention, "It was called a drill since when farmers offered to sow their beans and also peas into networks or furrows by hand, they dubbed that action drilling." Tull's improved drilling technique allowed farmer to sow three rows of seed simultaneously.

Tull took more scientific interest in tree nourishment. He correctly theorized the plants need to be an ext widely spaced and the soil roughly them thoroughly damaged down during growth. He more theorized the plants surrounding by loosened soil would grow far better not only during sowing, yet in the at an early stage stages of growth as well.

Tull's theory, however, was based ~ above a an essential error. He believed that the nourishment i m sorry the plant take it from the earth was in the kind of minute particles of soil. The did not think that animal manure, which was typically used as fertilizer, listed the plant with nourishment, but rather it noted a fermentative action in break up the soil particles. He saw no extr value in manure. He was very criticized for this belief.

In 1709, he moved to a thoreau of inherited soil in Hungerford, dubbed Prosperous Farm, whereby he continued his novel agriculture methods. In 1711, a pulmonary disorder sent out him to Europe searching for treatment and also a cure. While traveling, he listed the farming methods to work in the vineyards in the Languedoc area the France and in Italy, wherein it was usual practice to hoe the ground in between the vines fairly than manuring. On returning to prosperous in 1714, he applied the same practice on his fields of grain and also root crops.

Tull's crops were sown in widely spaced rows to allow the horse, drawing the hoe, come walk without damaging the plants, while permitting tillage to the soil during most the the period of growth. This ongoing growing of the soil while the tree was cultivation was the central point the Tull's theory and also the practice proceeds today. He thought that the cultivation of the floor released nutrients and also reduced the require for manure. While reportedly successful – he grew wheat in the same field for 13 succeeding years there is no manuring – some believe that is more likely the the an approach succeeded since it simply prevented weeds from overcrowding and also competing through the seed.

At the time, there was much skepticism towards Tull's ideas. His particle drill was not immediately popular in England, back it was quickly embraced by the colonists in new England. In 1731, Jethro Tull released "The new Horse Houghing Husbandry: or, one Essay ~ above the values of Tillage and Vegetation." The publication caused good controversy and also his theories dropped into disrepute, an especially his opinion on the worth of manure because that plant growth.

Although Tull set the structures for modern techniques that sowing and also cultivation, a hundred years passed prior to his seed-drill displaced the ancient technique of hand broadcasting the seed. While several other mechanical seed drills had also been invented, Tull's rotary mechanism was a major influence on the agricultural change and its affect can tho be watched in today's methods and also machinery. His seed drill was improved in 1782 by including gears come the distribution mechanism.

Tull passed away in the town where he was born in Shalbourne, Berkshire, England, on February 21, 1741, in ~ the age of 67.
