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 brown and/or earth:
“What have Massachusetts and the North sent a few sane representatives to Congress for, of late years?... All their speeches put together and boiled down ... do not match for manly directness and force, and for simple truth, the few casual remarks of crazy John Brown on the floor of the Harper’s Ferry engine-house,—that man whom you are about to hang, to send to the other world, though not to represent you there.”
—Henry David Thoreau (1817–1862)
“I need not say what match I would touch, what system endeavor to blow up; but as I love my life, I would side with the light, and let the dark earth roll from under me, calling my mother and my brother to follow.”
—Henry David Thoreau (1817–1862)
