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.
... Brown earths have a long history of being a major grouping in most soil classifications ... in the B horizon, and tend to what, in the British classification, is called a brown podzolic soil ... Brown earths are also classified in the German and Austrian soil taxonomy as "Braunerde." Braunerden are widespread and frequently occur on unconsolidated parent sand or loess parent materials ...
Famous quotes containing the words earth and/or brown:
“Laugh, and the world laughs with you;
Weep, and you weep alone,
For the sad old earth must borrow its mirth,
But has trouble enough of its own.”
—Ella Wheeler Wilcox (18501919)
“The human body is not a thing or substance, given, but a continuous creation. The human body is an energy system ... which is never a complete structure; never static; is in perpetual inner self-construction and self-destruction; we destroy in order to make it new.”
—Norman O. Brown (b. 1913)
