| Summary: | Qualitative land accounting plays an important role in the efficient use of agricultural land, the targeted placement of crops and the imposition of taxes on land users. Today, the quality of irrigated agricultural land shows the use of traditional methods in determining, assessing and mapping is inefficient in terms of time and cost. This, in turn, increases the need for fast, resource-efficient and science-based methods of modern geographic information system (GIS) technologies to address these issues. This article describes the results of scientific research on the compilation of histogram maps of soil quality indicators and geostatistical analysis using GIS technologies to determine the quality of irrigated agricultural lands. Hereby, the quality of soils was mapped in an automated system using the method of quality colors, the results of geostatistical analysis were converted into cartographic data and a new scale of values was developed. Geostatic analysis was performed in ArcGIS based on agrochemical cartogram data of land contours.
