1 The Improvers

2 Jethro Tull Jethro Tull born in 1674 is considered to be one of the early proponents of a scientific approach to agriculture. He helped transform agricultural practices by inventing or improving numerous implements.

3 At the time, seeds were distributed into furrows ('drilling') by hand
At the time, seeds were distributed into furrows ('drilling') by hand. Tull invented a machine to do the work for him. He designed his seed drill with a rotating cylinder. Seeds passed 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, then immediately covered by a harrow attached to the rear. This limited the wastage of seeding and made the crop easier to weed.

4 While several other mechanical seed drills had also been invented, Tull's complete system was a major influence on the agricultural revolution and its impact can still be seen in today's methods and machinery.

5 Turnip Townshend Viscount Townshend is famous for introducing to England the four-field crop rotation, (wheat, barley, turnips and clover).

6 Crop Rotation

7 The system (wheat, barley, turnips and clover), provided a fodder crop and grazing crop allowing livestock to be bred year-round. Crop rotation increased productivity by avoiding leaving the soil uncultivated ( fallow) Crop rotation also prevented the build-up of crop-specific soil pests and diseases The four-field crop rotation was a key development in the British Agricultural Revolution

8 As a result of this, and other agricultural experiments he became known as Turnip Townshend. Although a figure of some fun, ( turnips being his favourite topic of conversation) his agricultural reforms were extremely important.
