Economic mechanisms of state regulation play a crucial role in creating economic and legal conditions for profitable and rational use of productive agricultural land in conditions of constant intensification and growth of capital intensity of production. The role of the information basis for the implementation of the provisions of the digitalization of the agrarian economy is assigned to certification, aimed at an objective assessment of land as a means of production, an object of real estate and taxation. The substantiation of the fundamental aspects of certification of agricultural lands according to fertility parameters is given, which are: land as the primary object of certification, taken into account in the Unified federal information system for agricultural lands; soil difference, as a spatial object for assessing fertility in the land; standard crop yields on arable land and productivity of natural forage lands, as a quantitative measure of fertility assessment. Using the example of an arable land plot in the Saratov region, the form of the section of the agro-ecological passport "Agro-production characteristics of the soil cover of an agricultural land plot" is proposed, which ensures the certification of agricultural land as an information basis for the implementation of management digitalization mechanisms.
