The study aimed to develop a methodology for determining zones of intra-field heterogeneity for precision farming. In this study, we took into account the Belarussian national land use system which provides for the absence of private ownership of agricultural land. The spatial distribution of intra-field heterogeneity zones within the land use area of 7549.49 thousand hectares was identified using the analytical hierarchy process (AHP). The algorithm for determining zones of spatial heterogeneity provides for: (1) the selection of indicators and their ranking; (2) developing a pairwise comparison matrix, (3) estimating relative weights and (4) assessing matrix consistency. It is recommended to use data from agrochemical soil studies which are conducted centrally every 4 years for each agricultural enterprise as input parameters. These data include the humus content in the soil, the content of available phosphorus and potassium, soil pH, and the content of B, Cu, Zn, Ca, and Mg. The data should be carefully examined using spatial statistics tools to provide a more accurate delineation of the management-zones boundaries. The developed technique makes it possible to determine fertile and marginal areas within each field and differentiate the use of fertilizers, taking into account the presence of intra-field heterogeneity. This will reduce the total cost of purchasing and applying phosphorus fertilizers by 34 $·haE−1 and potash fertilizers by 9 $·haE−1 due to the redistribution of the fertilizer dose calculated for the planned yield, taking into account the identified site-specific management zones. At the same time, the level of chemical pressure per hectare of arable land will decrease by 6.7% without loss of crops productivity.

The application of institutional theory in the development of land management and land surveying to solve land problems in the period of globalization is due to the problems of human security and sustainable development. Institutional theory must justify the use and protection of land not only as a material but also as a public good. Four scientific positions were highlighted, which characterize the international institutionalization of land organization and land planning and related processes: 1) international institutionalization of land organization and land planning as a process of transition to international principles and standards of sustainable land management; 2) international institutionalization of land organization and land planning as a process of creating information on land ownership to ensure comparability of land statistics in the field of land resources and geospatial database and statistical reporting of different countries; 3) international institutionalization of land organization and land planning as a process of unification and harmonization of information systems for land accounting at the international level; 4) international standardization as a process of bringing national norms of territorial and spatial planning of land use development to international level while preserving essential national peculiarities. The relationship between the components of the process of globalization of land management and land surveying is characterized by the impact of globalization on the development of land management and land management. Implementation of institutions and institutes of land management and land surveying is carried out through coordination, redistribution, transactional and capitalization functions for the formation of sustainable (balanced) land use.
