Abstract
The fodder crop rotation soils were used to separate the contributions of fungi and bacteria to substrate-induced respiration (SIR) with the help of antibiotics. The studied soils have shown the predominant contribution of fungi (62,78-79,45%) to the total SIR. The fungal-bacterial ratio in the studied variants consists of 1,69-3,87 respectively.
Key words: Antibiotics, Bacteria, Crop rotation, Fungi, Microbial community, Selective inhibition, Substrate-induced respiration.
