Microorganisms in the soil have a very important role because they participate in numerous processes. Intensive and/or inadequate use of the soil leads to disturbance of the plant - microbial interactions, a decline in productivity, and degradation. The abundance and microbiological activity of a certain ecosystem are considered indicators of soil fertility. In this paper, surface (0-20 cm) and subsurface (20-40 cm) samples of grassland, agricultural soil, forest soil and coal-mine-affected soil at the Banovići municipality (Tuzla Canton, Bosnia and Herzegovina) taken in October 2021 and April 2022 were used for chemical and microbiological characterization. Chemical analyses were performed using the standard methodology, while the microbial count was determined using the agar plate method. Enzyme production was expressed through dehydrogenase activity. The lowest pH value was recorded in forest soil, while the highest in the grassland. In all samples, microbial abundance decreased with increasing soil depth. The lowest microbial activity was observed in coal mine-affected soil. The highest value of the total number of bacteria and ammonifiers was recorded in forest soil. Oligonitrophiles were most abundant in agricultural soil, while the number of actinomycetes was highest in grassland. Dehydrogenase activity was highest in forest and agricultural soil. In most of samples, microbial abundance was higher in spring, while dehydrogenase activity was higher in autumn. This research confirms the impact of land use on microbial abundance as parameter of soil quality. [ABSTRACT FROM AUTHOR] |
