The results of processing and analysis of spatial and temporal information about soils and forest stands on geoinformation technologies are presented. Spatial analysis of combined soil and forestry data showed that the most productive plantings were confined to sod-podzolic automorphic soils. In the main coniferous forest-forming species, such as European spruce and pine, when signs of hydromorphism appear, productivity significantly decreases. Among the studied plantings, the lowest-yielding ones are formed on swamp-podzolic soils. Retrospective analysis revealed a noticeable improvement in productivity and breed composition that occurred in the late 1970s and early 1980s. The assessment of the current situation shows that there is a certain reserve for increasing the productivity of existing forest stands, associated with a more effective use of the natural fertility of forest soils.
