The ability to perform this function is referred to as soil fertility. The clay and organic matter (OM) content of a soil directly influence its fertility. Greater clay and OM content will generally lead to greater soil fertility. The soil in figure 2 has a dark brown to black color, indicating abundant OM accumulation, and a highly fertile soil.
The link between soil functions and various soil properties such as substrate, texture, and humus content for soils at urban, industrial, and mining sites can be made using a set of indicators of soil quality such as those developed in Germany: rooting depth, wetting and aeration, nutrient status, and acid neutralization capacity. The high degree of surface sealing in urban soils limits the ...
For example, soil water holding capacity is a soil property related to water dynamics and filtering and buffering; however, a sandy soil with a low water holding capacity will not provide those functions as well as a clay loam soil with a high water holding capacity.
Soil functions are general capabilities of soils that are important for various agricultural, environmental, nature protection, landscape architecture and urban applications. Soil can perform many functions and these include functions related to the natural ecosystems, agricultural productivity, environmental quality, source of raw material, and as base for buildings.

Nov 8, 2024 · soil, the biologically active, porous medium that has developed in the uppermost layer of Earth’s crust. Soil is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of injurious wastes, and as a participant in the cycling of carbon and other elements through the global ecosystem.
