    Microbiological and enzymatic research has been conducted in the field experiment modeling different supply of Luvisol sandy loam soil with exchangeable magnesium (71, 84, 137, 172, 181 and 243 mg/kg) and even exchangeable acidity. It’s established that within the diapason of 70–170 Mg2+ content in soil and with NPK-fertilization it’s observed the increase of soil microbial biomass, metabolic activity of microbial communities, intensity of the main microbiological processes which regulate soil fertility – ammonification, carbonhydrates mineralization and plant residues humification.
