Biogeochemical Cycling of Macroelements in Soils

Soil is a unique natural system. A major property of the soil is the close interrelation of its constitutive living and non-living components. An artificial separation of the soil components destroys it completely as a system and makes the existence of soil impossible. V. I. Vernadsky aptly named the soil a biolatent body . 

The soil has evolved as a system with interrelated biological activity of various groups of living organisms. We can mention such groups as 

Individual amino adds total tree amino acids 

Various forms of dead organic matter, fragments of durable hypogenic minerals, and numerous products of biogeochemical and geochemical transformations and weathering represent the non-living part of soil. 

The provision of photosynthetic organisms with elements of soil nutrition is related to the inner part of soil s biogeochemical structure and is connected to two major soil components. The first of these is the dead organic matter and the second is the soil s
