The study aims to assess the adaptability of farming methods realized in zonal soil and climatic conditions within post-virgin land regions of the Ural and West Siberia, their nature-like and resource-saving orientation. The main evaluation criteria were the completeness and uniformity of the formation of the biological mass of field agrocenoses by analyzing the spatial distribution of the normalized difference vegetation index (NDVI). The public satellite images Landsat 8 and Santienel with a spatial resolution of 15-30 m/pixel, posted on online resources OneSoil.ai and Santienel-hub.com., were used as the NDVI data source. The results of the conducted studies have confirmed the high “diversity” and low realization of the biological potential of the cultivated crops with traditional resource-intensive cultivation methods, which have become a consequence of the widespread non-renewable production of soil resources. At the same time, the optimization of nature-like resource-saving agricultural practices and their adaptation to zonal landscape-adaptive farming systems confirmed the status of an effective means of improving the habitat of cultivated plants. According to the results of the analysis of agricultural technologies in model farms, cultivating practices that promote increasing the completeness and uniformity of the formation of biological mass in the conditions of modern climatic and anthropogenic challenges are systematized.
