Was studied an important methodological aspect of the application of the enzymatic activity of monitoring and diagnosing the condition of soil - seasonal variability of soil properties.We investigated character of the seasonal dynamics of enzyme activity, humus content, soil temperature and moisture.Indicators of enzyme activityvaried seasonally. The most varying indicator was dehydrogenase activity, the less -invertase and catalase.Oxidoreductasesactivity were higher in spring and at the end of the summer. The variation of invertase activity depends on hydrothermal parameters and levels of organic matter in soils.Similarity of seasonal changes in enzyme activity in the different soil layers was established.
