The studies compared soil parameters in the subtropics of the Lankaran region and the mountain landscapes of the Sheki region. An analysis of enzyme distribution in the soil profile showed that microbial communities with lower species diversity were restricted to the deeper soil layers. Experiments revealed that the addition of substrate and nutrients elicited a significantly stronger response and stimulated enzyme activity outside the original microfoci than within them. Furthermore, the activity of soil enzymes within the original microfoci themselves was less restricted than in the surrounding soil. Enzyme activities (catalase, urease, and phosphatase) in mountain meadow soils on the mountain plateaus of the Lankaran and Sheki regions were studied. For the first time in Azerbaijan, a comparative study of modern research findings from two regions with different ecological conditions was conducted. This is of great importance for the development of agriculture in the country.
