Tull's crops were sown in widely spaced rows to allow the horse, drawing the hoe, to walk without damaging the plants, while enabling tillage to the soil during most of the period of growth. This ongoing cultivation of the soil while the plant was growing was the central point of Tull's theory and the practice continues today.
He believed that the cultivation of the soil released nutrients and reduced the need for manure. While apparently successful — he grew wheat in the same field for 13 successive years without manuring — some believe that is more likely that the technique succeeded because it simply prevented weeds from overcrowding and competing with the seed.
At the time, there was much skepticism toward Tull's ideas. His seed drill was not immediately popular in England, although it was quickly adopted by the colonists in New England. Although Tull laid the foundations for modern techniques of sowing and cultivation, a hundred years passed before his seed-drill displaced the ancient method of hand broadcasting the seed. While several other mechanical seed drills had also been invented, Tull's rotary system was a major influence on the agricultural revolution and its impact can still be seen in today's methods and machinery.
His seed drill was improved in by adding gears to the distribution mechanism. Tull died in the village where he was born in Shalbourne, Berkshire, England, on February 21, , at the age of Podcast: The Promise of Hydrogen. ASME Membership 1 year has been added to your cart.

Tom Ricci is the owner of Ricci Communications. In , he moved to Prosperous Farm in Hungerford, he was taken ill again and two years later decided to travel around Europe to improve his health and revisit some of the practices he had studied there.
In , he perfected both his system and machinery. He introduced new ideas pulverising the earth between the rows, believing that this released nutrients. He built a hoe and rake for lifting weeds to the surface where they could dry. There amongst his fellow gentry farmers he found a following. Not everyone was convinced and it caused great controversy at the time. Cannot be underestimated, the Industrial Revolution brought about a population explosion.
His genius and contribution to society and science should be ranked alongside that of much more familiar great names of his time. You can see the context of Tull and his seed drill with other science and technology developments on our industrial and agricultural page where there is a searchable table you can scroll through.

Jethro made good use of what he saw in the vineyards he visited and pulverized the earth between his rows on the farm. Although this was to a certain extent based on a false belief — that plants got nutrients from the ground — the method was effective. The latter decreased the need for manure. He used it for years after and eventually influenced the agricultural minds of the 18th century.
Like many great innovations, this one was also met with a wave of criticism. Its impact was so high that it was discussed a whole century after its appearance. Eventually, though, his role in the Agricultural Revolution was recognized. His machines outlived and outperformed the other inventions of the time.
Jethro Tull died on February 21, Even though he did not see the complete recognition of his tools, they were indeed an essential step in British and world farming.
