Soil protection in arid and semi-arid regions is not possible without soil water protection. In fact, soil moisture storage is a very important factor in the development of vegetation and thus soil conservation. Irregular use of land, such as tillage for steep slopes and irregular grazing, reduce the share of water infiltration in the soil and decrease soil moisture and vegetation, aggravating flood and drought phenomena that have occurred in recent decades. Every year it causes a lot of financial losses. Conversely, proper soil management and conservation land management practices make optimum use of the sky. The purpose of this project is to provide numerical data on soil moisture percentage during different growing season in different soils, slopes and land uses in a part of Stein Tea Basin. At least 30 areas were selected at a certain altitude that receive relatively uniform rainfall and, where possible, adjacent to each other. In selecting these areas, the differences in their type of use, soil, slope, direction and level of management were also taken into consideration. In addition to recording daily rainfall, soil properties, topographic and plant characteristics, soil moisture measurement at 20 and 50 cm depths, according to a specific time schedule during the period of general plant growth in the area (March to November) with the device TDR was measured. In addition, multivariate regression analysis determined the factors affecting moisture content. Based on these results, it was found that the variables of soil moisture, temperature, precipitation and field capacity can explain 0.6 variance of the independent variable, ie vegetation cover.
