soil dynamics
1Soil biology — is the study of microbial and faunal activity and ecology in soil. These organisms include earthworms, nematodes, protozoa, fungi and bacteria. Soil biology plays a vital role in determining many soil characteristics yet, being a relatively new… …
2Soil mechanics — is a discipline that applies principles of engineering mechanics, e.g. kinematics, dynamics, fluid mechanics, and mechanics of material, to predict the mechanical behavior of soils. Together with Rock mechanics, it is the basis for solving many… …
3Soil physics — is the study of soil physical properties and processes. It is applied to management and prediction under natural and managed ecosystems. Soil physics deals with the dynamics of physical soil components and their phases as solids, liquids, and… …
4Soil organic matter — (SOM) is the organic matter component of soil. It can be divided into three general pools: living biomass of microorganisms, fresh and partially decomposed residues, and humus: the well decomposed organic matter and highly stable organic material …
5Soil food web — The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Introduction Food webs describe the… …
6Soil — For other uses, see Soil (disambiguation). A represents soil; B represents laterite, a regolith; C represents saprolite, a less weathered regolith; the bottommost layer represents bedrock …
7Soil seed bank — The soil seed bank is the collective name for the store of seeds, often dormant, which are stored within the soil of many terrestrial ecosystems. Background Soil seeds banks of particular taxa have been classified according to the longevity of… …
8Patch dynamics — For the use of the term in physics, see Patch dynamics (physics). Patch dynamics is a conceptual approach to ecosystem and habitat analysis that emphasizes dynamics of heterogeneity within a system (i.e. that each area of an ecosystem is made up… …
9Mesotrophic soil — Mesotrophic soils are soils with a moderate inherent fertility. An indicator of soil fertility is its base status, which is expressed as a ratio relating the major nutrient cations (calcium, magnesium, potassium and sodium) found there to the… …
