Soil Science-related Lists
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection 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 soi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stagnogley
A stagnogley soil is a type of non-alluvial, non-calcareous soil that is typically loamy or clayey soil with a dense, impervious, subsurface horizon (soil), horizon. Stagnogley soils are related to the pseudogleys and are classified as gleyic soils. The name "stagnogley" comes from the soil's gley dynamics. This hygroscopic soil is nutrient-poor, often highly acidic, and poorly aerated, making it unsuitable for farming due to poor crop growth.Fritz Scheffer, Paul Schachtschabel: ''Lehrbuch der Bodenkunde.'' 15th edn., newly revised and expanded by Hans-Peter Blume. Spektrum, Heidelberg, etc., 2002, . With a shallow topsoil layer and a moderately stony subsoil, stagnogley soil is mainly used for woodland,''Stagnogley'' in: ''Microsoft Encarta'' supporting tree species that thrive well in these conditions, such as the English Oak. Formation This type of soil, whose topsoil becomes bleached due to continual waterlogging, is often formed on sand-rich material over dense, sandy-loa ...
