Impact of microbiological preparations on improving agrochemical efficiency of fermented organic manure

摘要

The effective impact of biological preparations in combination with organomineral system of fertilization on fertility of soft sod-podzolic sandy soils is elucidated, which manifests itself in increasing the agrochemical indices of the soil fertility up to 28,6 % in direct action and up to 41,6 % in the after-effect. The most efficiency biological preparation is Polymixobacterin, the lowest efficiency is Baikal EM-1
