Sažetak

The aim of this paper is to determined dynamics and vertical distribution of nutrients and microbial communities in calcocambisol and terra rossa in natural lawns in Mostar district (Bosnia and Herzegovina). The main research was focused on total number of bacteria, actinomycetes, fungi, free-living nitrogen fixers, ammonifiers and Azotobacter sp., as well as on the chemical properties of soils. Microbiological and chemical properties of soils were determined during the 2011 in different depths using the standard methodology. Chemical analyses of the examinated soil showed the acid pH value, poor to moderate humus content, as well as total N and available P and K. Results of research confirm the strong influence of season of sampling, soils depth and their interaction on microbial activity. Number of microorganisms was controlled by pH value, humus and total nitrogen content, soil moisture and temperature. In both soil types, total bacterial number was the highest in spring, while number of fungi and actinomycetes was the highest in autumn. Azotobacter sp. was only detected in surface layer of soils. These results confirm that understanding of microbial, physical and chemical properties of soil and their interaction, which can be controlled by human activities, is necessary for improvement of soil fertility.
