Farms in Britain
British agriculture is based on high-quality farm machinery and utilization of fertilizers. It is greatly influenced by the climate. Britain has a mild climate. The temperature seldom exceeds 32ºC or falls below zero. Thus the farmers work in the fields all the year round.
Most of the farms are less than 50 acres each. The type of farm depends on many factors: climate, soil, slope and altitude.
We can find arable farms, dairy farms and mixed farms. In the eastern part of Great Britain most farms are arable. The farmers having such farms grow different crops: wheat, barley and oats. In the western part of the country most farms are dairy. Farmers keep milking cows, sheep, pigs or poultry on their farms. Sheep-breeding is found in Wales and Scotland, cattle-rearing in the south-east of England (Kent), horticulture in Cornwall and Yorkshire.
Small farms in Britain are usually mixed farms on which farmers grow crops and keep animals as well.
Today the main tendency in agricultural development of Great Britain is that small farms are gradually disappearing because they cannot compete with modern industrial farms based on up-to-date agricultural machinery.
British farmers are working hard to earn their living, to maximize the yield and minimize the cost of production, to supply the population of the country with various foodstuffs of high quality, to ensure farther progress in all agricultural branches.
