Investigation on the use of pharmaceutic industry wastes as organic fertilizers was conducted by two runs: 3-year experiment in phytometers with sand soil (plant sequence - a mixture of leguminous plants and rye), and 3-year experiment in randomized blocks on brown soil (plant rotation - potatoes, oats and rye). The effect of postfermentation spawn on the yield and some quantitative and qualitative traits of test plants was examined. The obtained results suggest the possibility of using the above wastes as fertilizers. Their application increased the yield of potatoes and oats and contributed to an increase of C and N content in the soil
