摘要：The universality, comprehensiveness and adequacy of biological soil diagnostics methods make them widely used in monitoring studies of anthropogenic effects on the soil. Soil samples of forest nurseries have been studied, directly under seedlings and in the steam field. Anthropogenic loading changes the biological parameters of the soil, leading to a decrease in soil fertility. The results of the assessment of the biological state of forest nursery soils used for the planting material of coniferous seedlings in Siberia by the level of enzymatic activity are presented. Analysis of soil quality by methods of research of oxidative and hydrolytic enzymes was carried out. Monitoring of enzymatic activity indicators of soils of forest nurseries of Krasnoyarsk region showed that by activity of catalase, invertase of urease they belong to medium-enriched. It has been established that in the soil of Uyarsky, Kansky and Kuraginsky forest nurseryscientists there is the highest rate of proteolytic activity. Low level of catalase enzyme activity revealed in Kazatinsky nursery against the background of high soil contamination with phytopathogenic microorganisms.
