Due to the imperfection of the regulatory regulation of the agricultural land use, the lack of fixed indicators that characterize rational use of this land category, the authors, solve the task of calculation method for integral parameters, characterizing the quality and rational use of such lands. The solution was based on the analysis of the results developed by existing scientific schools in the given field and our own research, including the set of particular parameters, their subdivision into groups, the variant of determination of their relative significance (weight) in final assessment. The fundamental aspect of the assessment system is emphasized, due to the diversity of the realization of their natural potential by agricultural areas similar in natural properties, which required the implementation of two groups of indicators – the quality and rational use of agricultural land. In order to determine the integral indicators of quality and rational use of agricultural land, the authors have developed an algorithm for calculating them in the geographic information system QGIS, consisting of certain stages. Automatic calcu-lation of integral indicators significantly speeds up and simplifies the process of analyzing the state of land use in a particular region, avoids mechanical errors in calculations.
