Microelements and mesofauna structure in the soils of landscape type protected area

An article provides characteristics of soil mesofauna and microelement composition of soils in various biogeocenoses in the case of landscape-adaptive farming system. Total value of Cd, Pb, Cu, Ni, Zn, Mn in examined soils did not exceed sanitary-hygienic standards (MAC and APC). Co and Fe content were usual for a tilled and natural grey forest soils of Tatarstan Republic. Artificial fertilizer use lead to the increased Cr content. Statistically significant differences in microelement composition, taxonomic and trophic groups abundance between biogeocenoses were shown. Taxonomic groups of soil mesofauna such as Litobiidae and Carabidae and representatives of phytophagous trophic group and Cd, Pb, Ni, Zn, Mn as well were the main variables in biogeocenoses discrimination in multidimensional analysis.
