Jethro Tull (agriculturist)This article is about the English agriculturalist. For the progressive rock band named after him, see Jethro Tull (band). Jethro Tull (1674–1741) was an English agricultural pioneer.
Tull also invented a horse-drawn hoe for clearing weeds, and made changes to the design of the plough that are still visible in modern versions. His interest in ploughing came from his war against weeds, and his belief that plants took their nourishment solely from the minerals in the soil and that organic emendation was not necessary. He knew that horse manure was filled with weed seeds, and hoped to avoid using it as fertiliser by pulverising the soil to make the minerals more available. Although Tull was in error on this latter point – the error of a pioneer, it should be noted – as a whole his innovations form part of the foundation of productive modern farming. His inventions were controversial at the time and were not adopted for many years. Tull died in Shalbourne, Berkshire. External link
