In fact, as Darwin observed more than a century ago, these seemingly small biological processes operating over long time periods and large spatial scales can make profound changes in the world around us, including the formation of soil. 217.160.166.73.

Critical Rewiews in Microbiology. A physiological method for the quantitative measurement of microbial biomass in soils. In climate science, biomass (biological matter) is any organic material that comes from plants, animals or vegetables, which is used for energy production (electricity or heat), or in industrial processes as raw materials for a range of energy products. Barber D.A. Moghimi A., Tate M.E. Brookes P.C., Tate K.R. 1978.

The findings might be significant in studies of the fate of nutrient flushes and of fertilizer P, especially in situations where leaching contributes to losses from the soil and possible accumulation in water supplies. The physical breakdown is performed mainly by medium-size invertebrates during their feeding activity, facilitating the colonization and invasion of soil microorganisms [17]. 1973. From 20 to 70% of the CEC of many soils (e.g., Mollisols) is due to organic matter. Plant and Soil, Jones J.G. Greater decreases of OC and TN were found in soils with acidic pH (<6.5) and sandy texture and in climate zones with mean annual temperatures around 10–20°C and mean annual precipitations >1000 mm [99]. 1979. 1982.

Most of the studies show reducing litter decomposition with metal pollution and relate this to alterations in soil fauna feeding activity and microbiological parameters (e.g., soil basal respiration, microbial biomass C, enzyme activities such as dehydrogenase, β-glucosidase and cellulose), but also to the suboptimal conditions prevailing in metal-contaminated soils.

The rest is used for the formation of new increasingly complex molecules of colloidal nature and dark color called humus. Organic matter dynamics are strongly influenced by soil fauna.
