English agriculturist who in about 1701 developed a drill that enabled seeds to be sown mechanically and spaced so that cultivation between rows was possible in the growth period. His chief work,
Horse-Hoeing Husbandry, was published in 1733.
Tull also developed a plough with blades set in such a way that grass and roots were pulled up and left on the surface to dry. Basically the design of a plough is much the same today.
