Soil respiration is an important indicator of soil health because it indicates the level of microbial activity, SOM content and its decomposition rate. The research was aimed to study the relationships between soil respiration and other soil characteristic between different soil types that are under different land use system within small test area. Moisture, temperature and availability of organic substrate most influential factors that impact soil respiration and given that precipitation and temperature are uniformed in the studied area, the main goal was to find the soil indices that is closely correlated to soil microbial respiration on different soil types. The results showed that soil respiration was greatest in Rendzna and in the soils containing carbonates. In spite of heterogeneity of soil cover, which implies different soil physical, water, chemical and biological characteristics, the soil microbial activity was closely and positevly correlated with soil acidity, clay content, content of carbon and nitrogen.
