Description

The object of research - is microbiological mineralization and immobilization processes in gray forest soils at the application of various doses of CaCO3 and mineral fertilizers at the crops cultivation in seven-crops rotation. The purpose of research - is to establish the relationship of parameters of effective fertility with direction and intensity of agronomically important microbiological processes, stability of microbial groups of gray forest soil at the application of various systems of fertilization and liming. There is established that the liming of gray forest soil in dose of 1 hg is slowed the mineralization of soil organic matter: without mineral fertilization in 2 times, with mineral fertilization in 4 times, against the background of plowing biomass of green manure of culture and by-products of precursor in 1,4 times. Mineralization of nitrogen compounds as a result of liming also is become less intense: without mineral fertilization in 1,2 times, with mineral fertilization in 2,2 times. Activity of humus mineralization is decreased as a result of liming without mineral fertilization by 67 %, with mineral fertilization by 11%. The total biological activity of soil is increased as a result of liming in the variant without mineral fertilization by 23 %, with mineral fertilization by 43 %, against the background of plowing exogenous organic matter by 84 %.
