PROCEDURE OF TENDENCY MAP ON THE BASIS OF GEOGRAPHICAL INFORMATION SYSTEM OF JALILABAD CADASTRY DISTRICT

Abstract

As the inclination increases, soil erosion and, in general, the process of erosion on the slopes intensifies, the moisture content of the soil and soil-forming rocks decreases, the growth of agricultural crops and pastures weakens, and productivity decreases. Taking all this into account, we have developed a slope map with degrees based on the digital elevation model of the Jalilabad cadastral region (DEM file). Slope study and mapping is one of the key measures to protect soils from erosion as well as to combat erosion. When the slope reaches 3-4°, the washing of the soil is even faster. It is not recommended to plow the fields when the slope is 8-10° and more. From this point of view, as a result of our research, the inclination of the Jalilabad cadastral region has been studied. The lowest inclination range in the study area is 0-20. Low inclination is observed mainly in the plains of Jalilabad cadastral region. As you ascend to the heights, there is an increase in inclination. Taking into account the propensity in agriculture can lead to high yields.
