Abstract. The territory of the Republic of Tatarstan (RT) belongs
to the region with the most developed agriculture in Russia and the Middle
Volga region. However, the formation of a system of accurate farming in the
Republic is just beginning. To ensure precision farming, it is necessary to
precisely know cropland borders, as well as the agrochemical properties of
soils (pH, humus content, potassium and phosphorus content). The present
study was carried out based on aerial images analyses of the most
intensively used part of the RT both with identification of soil indicators
for each of the fields. The availability of information on the spatial
location of various cultivated crops makes it possible to assess the role of
soil characteristics in these crops.
