Moder is a forest floor type formed under mixed-wood and pure deciduous forests. [1][2] Moder is a kind of humus whose properties are the transition between mor humus and mull humus types. [3][4] Moders are similar to mors as they are made up of partially to fully humified organic components accumulated on the mineral soil. Compared to mulls ...
Forest humus form describes the various arrangement of organic and mineral horizons at the top of soil profiles. [1] It can be composed entirely of organic horizons, meaning an absence of the mineral horizon. [2] Experts worldwide have developed different types of classifications over time, and humus forms are mainly categorized into mull, mor ...
Mor humus is a form of forest floor humus occurring mostly in coniferous forests. [1] Mor humus consists of evergreen needles and woody debris that litter the forest floor. This litter is slow to decompose, in part due to their chemical composition (low pH, low nutrient content), but also because of the generally cool and wet conditions where ...
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, Korea, China ...
These forests play a role in the regulation of air and soil quality by preventing soil erosion and flooding, while also storing carbon in their soil. [5] Provisioning services provided by temperate deciduous forests include access to sources of drinking water, [ 12 ] oxygen, [ 13 ] food, timber , and biomass . [ 5 ]
Alfisol. Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semi-arid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility. "Alf" refers to aluminium (Al) and iron (Fe). Because of their productivity and abundance, Alfisols represent one of the more ...
A Palash tree in Ranchi, Jharkhand Sal trees (Shorea robusta) are found in forests of Chota Nagpur Plateau. The Chota Nagpur dry deciduous forests, a tropical and subtropical dry broadleaf forests ecoregion, encompasses the plateau. The ecoregion has an area of 122,100 square kilometres (47,100 sq mi), covering most of the state of Jharkhand ...
Red soil is a type of soil that develops in a warm, temperate, moist climate under deciduous or mixed forest, having thin organic and organic-mineral layers overlying a yellowish-brown leached layer resting on an illuvium red layer. Red soils are generally derived from crystalline rock.
