Dynamics of the structural state and enzymatic activity of calcic chernozem under the influence of biologically active drugs

The results of many years research on the individual and complex effects biologically active substances structural state enzymatic activity calcic chernozem – humic preparation Lignohumate microbiological fertilizer “Baikal-EM” are presented. It was found that contribute to an increase in activity, humus content improvement soil structure. When both preparations applied directly soil, maximum effect statistical reliability this characteristics shown even under extremely unfavorable weather conditions. At same time, coefficient during study period increases from 1.5 2-2.7 comparison with background variant, which makes it possible assess soils as “excellent”. In general, enzymes cultivation winter crops tended stable growth. cessation application liquid fertilizers transition a spring crop led decrease their return values.
