Soil Anchor
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stagnogley
A stagnogley soil is a typically non-alluvial, non-calcareous, loamy or clayey soil with a relatively impervious, subsurface horizon. Stagnogley soils are related to the pseudogleys and are a type of gleyic soil. The name of this hygroscopic soil derives from its gley dynamics. The nutrient-poor, often heavily acidified soil is poorly aerated and is not suited to arable use on account of the poor growth performance of cultivated crops.Fritz Scheffer, Paul Schachtschabel: ''Lehrbuch der Bodenkunde.'' 15th edn., newly revised and expanded by Hans-Peter Blume. Spektrum, Heidelberg, etc., 2002, . As a shallow topsoil with a moderately stony subsoil, it is mainly used for woodland.''Stagnogley'' in: '' Microsoft Encarta'' Because of its shallow nature it is only suitable for species of trees that thrive well in these conditions, such as the English Oak. Formation This type of soil, the topsoil of which becomes bleached as a result of continual waterlogging, is often formed on sand-r ...
