And the rest is grassland, part of which is fallow, then there is woodland for fruit trees and then there is grazing land for cattle and sheep, etc.... All this is part of agriculture.
(AFAIK, it is good practice to allow a portion of the agricultural land to lie fallow for a year, to allow for the soil to recover.) The above stats are the breakdown of total agricultural land, which is 71% of the land area of the UK. For want of a better reference, we come to Wikipedia: "Agriculture in the United Kingdom uses around 71% of the country's land area and contributes about 0.6% of its gross value added. The UK produces less than 60% of the food it eats and the industry's share of the national economy is declining. Despite skilled farmers, high technology, fertile soil and subsidies, which primarily come from the European Union (EU), farm earnings are low and falling, mainly due to low prices at the farm gate. With each generation, fewer young people can afford the rising capital cost of entry into farming and more are discouraged by low earnings. The average age of the British farm holder is now 59." Nevertheless, there is a trend now for the "city" folk moving to country areas to become farmers, according to some sources. As an aside, it would be a good idea also to read "How many people can the Earth support?" at http://www.ecifm.rdg.ac.uk/poppres.htm Gabriel
