INFLUENCE OF STRUCTURING AGENT AND HERBICIDE ON SOIL HUMIDITY AND STATE OF WEEDS ON THE WESTERN AND SOUTHERN SLOPES OF THE CHATKAL RIDGE IN UZBEKISTAN

This article describes the effect of soil structure formers and herbicide on soil moisture and on the state of weeds when creating forest plantations on different mountain slopes of the Chatkal Range.

From the experiments, it was found that the structurizers used in the experiment of 2 types of structure-forming agents in the hottest summer period (July-August), when there was a complete absence of precipitation, contributed to an increase in soil moisture in the root layer of plants  2-4% higher than the wilting moisture, which was observed in the control variant.

In 2017, during the same period, the coverage of the terrace canvas with herbage was: treated with polyameliorant 46.6%, treated with CMC - 51.6%, and not treated (in control) - 59.3%.
