To develop sensitive indicators of soil quality even in sustainable vegetable production it is on high importance. It is that microbiological indicators are used with the intention to foreseen a biological effect of possible impact on organic matter decomposition. Soil organic matter itself has significance for soil quality as it can influence many different soil properties in resumption to soil productivity. The aim of the present study was to assess the responses of soil microbial biomass and soil dehydrogenase enzyme activities on the soil improvement with biological active materials. Bulk soil was collected along the vegetation period from the plant rhizosphere in 2017. It was estimated that microbial biomass as well as dehydrogenase activity were continuously increasing within vegetation period in sites with biological improvement. The trends in microbial biomass along with improvement could also be possibly regulated by the changes in carbon and nitrogen ratios of the biological active material. However, the difference in dehydrogenase enzyme activity could be related with even the short-term of the application and sufficiently were contributed to the microbial stimulation by the organic matter from the biological active material as well as the availability of organic carbon.
