Brown Earth

Brown earth is a type of soil. Brown earths are mostly located between 35° and 55° north of the Equator. The largest expanses cover western and central Europe, large areas of western and trans-Uralian Russia, the east coast of America and eastern Asia. Here, areas of brown earth soil types are found particularly in Japan, the Koreas, China, eastern Australia and New Zealand. Brown earths cover 45% of the land in England and Wales. They are common in lowland areas (below 1,000 feet) on permeable parent material. The most common vegetation types are deciduous woodland and grassland. Due to the reasonable natural fertility of brown earths, large tracts of deciduous woodland have been cut down and the land is now used for farming. They are normally located in regions with a humid temperate climate. Rainfall totals are moderate, usually below 76 cm per year, and temperatures range from 4°C in the winter to 18°C in the summer. They are well-drained fertile soils with a pH of between 5.0 and 6.5.

Famous quotes containing the words earth and/or brown:

    Alas! While your ambitious vanity is unceasingly laboring to cover the earth with statues, with monuments, and with inscriptions to eternalize, if possible, your names, and give yourselves an existence, when this body is no more, why must we be condemned to live and die unknown?
    Thomas Paine 1737–1809, U.S. writer and magazine editor. Pennsylvania Magazine, pp. 362-4 (1775)

    He who never sacrificed a present to a future good or a personal to a general one can speak of happiness only as the blind do of colors.
