Agriculture in England
Agriculture in England is today intensive, highly mechanised, and efficient by European standards, producing about 60% of food needs with only 2% of the labour force. It contributes around 2% of GDP. Around two thirds of production is devoted to livestock, one third to arable crops. Agriculture is heavily subsidised by the European Union's Common Agricultural Policy and it is not known how large a sector it would be if the market was unregulated. The GDP from the farming sector is argued by some to be a small return on the subsidies given but is argued by others that subsidy boosts food security and therefore is justified in the same way defence spending is.
The main crops that are grown are wheat, barley, oats, potatoes, sugar beets, fruits and vegetables. The livestock that is raised include cattle and sheep. In the drier east, farmers grow wheat, barley, oats, potatoes, and sugar beets.
Between the 16th century and the mid-19th century, Great Britain saw a massive increase in agricultural productivity and net output. (See: British Agricultural Revolution.) New agricultural practices like enclosure, mechanisation, four-field crop rotation and selective breeding enabled an unprecedented population growth, freeing up a significant percentage of the workforce, and thereby helped drive the Industrial Revolution. By the early 19th century, agricultural practices, particularly careful selection of hardy strains and cultivars, had so improved that yield per land unit was many times that seen in the Middle Ages and before. In the late nineteenth century a slump badly affected arable farming, known as the Great Depression, which is usually dated from 1873 to 1896. The depression was caused by the dramatic fall in grain prices following the opening up of the American prairies to cultivation in the 1870s and the advent of cheap transportation with the rise of steam ships.
The 18th and 19th centuries also saw the development of glasshouses, or greenhouses, initially for the protection and cultivation of exotic plants imported to Europe and North America from the tropics. Experiments on plant hybridisation in the late 19th century yielded advances in the understanding of plant genetics, and subsequently, the development of hybrid crops. Storage silos and grain elevators appeared in the 19th century.
