STUDY OF SOIL MOISTURE DYNAMICS IN THE TUGAI FORESTS OF THE ILI RIVER

Abstract

The article presents the results of a study of the dynamics of changes in soil moisture in tugai forests during the growing season in the floodplain of the Ile River. These research works were carried out on the territory of the state forest fund of the municipal state institution "Bakanas forestry" in the Bakanas forestry. In the course of determining the dynamics of soil moisture, plots were selected in the riverbed and central terraces on the right bank of the Ile River. The study aims to determine the degree of soil moisture change in the tugai forests of the Ile River floodplain by seasons. The works were carried out on this territory in the period from April to September 2021. To study the dynamics of moisture availability of soil horizons, samples were selected in threefold repetition in the spring, summer and autumn periods. Soil samples were taken from each genetic horizon to determine the soil moisture level. Samples were taken from the earth's surface at intervals every 10 cm to a depth of 100 cm and the moisture content in the soil was determined in laboratory conditions. Soil moisture was determined by the thermal weight method. Based on the data obtained, the dynamics of changes in soil moisture during the growing season is analyzed, the results of which are presented in the form of tables and graphs.
