Special attention is paid to semivariogram analysis - the main mathematical tool of geostatistics used to describe the statistical structure of spatially varying fields variables. It is shown that the assessment and analytical approximation of the efficiency variograms, the strategy of planning technological impacts and, consequently, the feasibility of using the exact technology in each specific case depend on the soil-climatic variation characterizing the spatial variability of the controlled factor as well as on the field scale defined as the ratio of its actual dimensions to the lag of the variogram function. The precision agriculture and strategy of agro-technological solutions adaptation planning for agricultural production are based on the idea of the possibility of a significant increase in yield, significant resources saving and decrease in natural-anthropogenic heterogeneity on the environment, which is realized by differentiating the norms of technological impact on the crop and its habitat in accordance with the spatial temporary variability of soil and other factors of productivity within an individual agricultural field.
