	Much of the microarthropod group are discovered in most types of soils. A square meter of woodland floor could contain hundreds of thousands of individuals representing thousands of different species, mainly [[mites]] and [[collembola]]. Microarthropods have a substantial impact on the [[decomposition]] process in the forest floor and are important reservoirs of biodiversity in forest ecosystems. They also control the distribution and abundance of fungi in soil, and they stimulate microbial metabolic activity, thereby amplifying microbial immobilization or mineralization of nutrients [7].

	Due to their relatively small body size and total biomass, which is lower than that of fungi, bacteria and other taxa such as nematodes and [[protozoa]], microarthropods may rather indirectly than directly affect soil structure. However, in some cases the impact of the production of assumedly large amounts of organic material in form of eggs might play an important role as direct starting points for microaggregate formation [6]. Many microarthropods, especially springtails and soil mites, are responsible for breaking down organic material into a form that bacteria can consume, and are fundamental to the creation of [[humus]] and the formation of soil [8].

	In soils where fungi dominate, there are six mechanisms of interaction with microarthropods. Two control fungal distribution and abundance, namely selective grazing of fungi by microarthropods and dispersal of fungal inoculum by microarthropods. Four additional mechanisms stimulate microbial activity: (1) direct supply of mineral nutrients in urine and feces, (2) stimulation of bacterial activity by microarthropod activity, (3) compensatory fungal growth due to periodic microarthropod grazing, and (4) release of fungi from competitive stasis due to microarthropod disruption of competing mycelial networks [7].
