Answer 1

Answer:

The Agricultural Revolution was the unprecedented increase in agricultural production in Britain due to increases in labor and land productivity between the mid-17th and late 19th centuries. However, historians continue to dispute whether the developments leading to the unprecedented agricultural growth can be seen as “a revolution,” since the growth was, in fact, a result of a series of significant changes that took place over a long period of time.

One of the most important innovations of the Agricultural Revolution was the development of the Norfolk four-course rotation, which greatly increased crop and livestock yields by improving soil fertility and reducing fallow. Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons to help restore plant nutrients and mitigate the build-up of pathogens and pests that often occurs when one plant species is continuously cropped.

Following a two-field crop rotation system common in the Middle Ages and a three-year three field crop rotation routine employed later, the regular planting of legumes such as peas and beans in the fields that were previously fallow became central and slowly restored the fertility of some croplands. In the end, it was the farmers in Flanders (in parts of France and current day Belgium) that discovered a still more effective four-field crop rotation system, using turnips and clover (a legume) as forage crops to replace the three-year crop rotation fallow year.

The four-field rotation system allowed farmers to restore soil fertility and restore some of the plant nutrients removed with the crops. Turnips first show up in the probate records in England as early as 1638 but were not widely used until about 1750. Fallow land was about 20% of the arable area in England in 1700 before turnips and clover were extensively grown. Guano and nitrates from South America were introduced in the mid-19th century and fallow steadily declined to reach only about 4% in 1900.
