Abstract

A simulation experiment has shown that it is reasonable to use biologically active mixtures such as the liquid-phase biological products (LBP) as soil fertilizers. LBP produced by bioconversion of organic raw materials. The biological product in its composition contains a large quantity of the microflora, available phosphorus and potassium. On fine-grain soils demonstrated the greatest effect on LBP, which accumulate mobile biogenic components and show increasing biological parameters such as nitrogen soil mineralization and redox rate. The results of the regression analysis indicated strong relationships between individual values in different soils. It is significant that between K₂O and P₂O₅ showed significant relationships for all soils. For fine-grain sod-podzol soils revealed consistently high and positive correlation coefficients between these indices. In fact, we observed a high stable level of responsiveness of these soils on the typical LBP indicators.
