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 ...
Soil pH is a function of many soil forming factors, and is generally lower (more acidic) where weathering is more advanced. [ 43 ] Most plant nutrients, with the exception of nitrogen , originate from the minerals that make up the soil parent material.
Soil has a crucial function in the global carbon cycle, with the global soil carbon pool estimated to be 2,500 gigatons. This is 3.3 times the amount of the atmospheric pool at 750 gigatons and 4.5 times the biotic pool at 560 gigatons.
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
For example, while some studies have found that reductions in the abundance and presence of soil organisms results in the decline of multiple ecosystem functions, [28] others concluded that above-ground plant diversity alone is a better predictor of ecosystem multi-functionality than soil biodiversity. [29]
Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. [1] It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans.
