Determination of spatial distribution of water soluble sodium (23Na) in soils and estimation of the level of sodium contamination of agricultural lands in zone of Production Association Belaruskalij enterprises activity (the Republic of Belarus) were fond out. Soils were scaled by the level of contamination with water soluble sodium. The preliminary scale of soils by level of sodium contamination was presented. Schemes of land pollution were presented on the basis on the preliminary scale. Content of water soluble sodium in soils adjacent to Production Association Belaruskalij depended on the distance from emission source, on prevailing wind, on soil cover and level of soil hydromorphism. Concentration of water soluble sodium in soil was within the level of 12-20 mg/kg of soil that was higher than the accepted indices of background sodium content in soil on the territory of forth mine camps (the average accepted content of water soluble sodium in Belarus - 10 mg/kg). In the immediate area to the sludge depositories of the Enterprise (50-150 meters) there were revealed local areas with strong degree of soil sodium contamination in concentration of 529-915 mk/kg of soil, that was 50-90 times higher than the background level of sod-podzolic soils. All studied catena soils were characterized by high sodium content (3100-3200 mg/kg of soil). Content level of water soluble potassium against its total content in the arable layer was increasing from sod-podzolic sandy automorpfous soil to glay soil, from 1,5% up to 5,0 %, respectively
