Activity of hydrolite soil enzymes in the phytogenic field Acer negundo L. in the conditions of the broken inundated communty

The results of the activity of hydrolytic enzymes of soil in the phytogenic field of Acer negundo L. in the conditions of disturbed floodplain communities are given in the article. The object of the research was soil samples, selected under maple plantations of ash-leafed, transformed plant communities in the floodplain of the River Tom between the Krasnoe and Long lakes within the city of Kemerovo. Sampling was carried out in three categories of the closeness of tree crowns. As an inspection, the outer zone of single trees was chosen. Studies of the enzymatic activity of the soil were carried out on freshly collected material in triplicate from a mixed sample. It was revealed that the highest level of activity of hydrolytic soil enzymes on the investigated sites in disturbed floodplain communities was observed near single Acer negundo trees in open stands, compared to other tree groups and with control. The greatest activity of enzymes in the middle of the growing season was established, with invertase activity in all soil samples higher than proteases and phosphatases. The average level of soil biochemical activity is established at the sites of the experiment, which indicates the possibility of using the obtained data as diagnostic signs of the soil state and its enzymatic activity in specific soil and climatic conditions.
