The soil is cool, as often chalky as siliceous (rich in silica), and nearly always acidified by rain. The layer is characterised by the beech tree. The layer is characterised by the beech tree. The beech tree projects a deep shadow , and so its dense foliage usually excludes other woodland species.
The basic soil, along with calcium carbonate from the caliche, can prevent plants from getting enough nutrients, especially iron. An iron deficiency makes the youngest leaves turn yellow. Soil saturation above the caliche bed can make the condition worse. [22] Its hardness can also make digging for projects such as canals more difficult.
Chalk is a source of quicklime by thermal decomposition, or slaked lime following quenching of quicklime with water. [24] In agriculture, chalk is used for raising pH in soils with high acidity. [25] Small doses of chalk can also be used as an antacid. [26] Additionally, the small particles of chalk make it a substance ideal for cleaning and ...
Ludwig foresaw a future increase in the price of paper due to the increase of mass media. Since most of the natural forest timber was not suitable for paper production, Ludwig planned a site where the natural forest would be replaced by a tree farm. It would have to be started decades ahead to supply the future paper production.
Calcareous (/ k æ l ˈ k ɛər i ə s /) is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines.
The word badlands is a calque from the Canadian French phrase les mauvaises terres, as the early French fur traders called the White River badlands les mauvaises terres à traverser or 'bad lands to traverse', perhaps influenced by the Lakota people who moved there in the late 1700s and who referred to the terrain as mako sica, meaning 'bad ...

The lichen flora of chalk grasslands represents an often overlooked component of calcareous grassland biodiversity. A comprehensive survey of English chalk grasslands in the 1990s identified two main lichen communities: the widespread Lecideetum watsomiae association found on chalk pebbles and flints, and the more restricted Fulgensietum ...
