The results of a long-term field experiment with sugar beet on leached chernozem in the forest-steppe of the Central Chernozemic Zone are presented. The effect of organic and mineral fertilizers on soil supply with mobile phosphorus and potassium and their dynamics in time and space has been shown. Criteria of correlation in the 'fertilizer-soil nutrient status-crop productivity' system and their probability parameters have been calculated.
