| description | In this article there are present the results of six-year study of infiltration of nitrogen through the sand soil (loamy sand). Every year the soil was fertilized by compost (from sewage sludge) and equivalent doses of nitrogen in mineral fertilizers. Two variants of compost fertilization (K1-10 and K2-15 g N·m-2) were used. Additionally two variants of NPK with equivalent doses of nitrogen as an ammonium nitrate supplemented with PK as a superphosphate and potassium salt were applied. Systematically there were investigated the volume of all leachates and their chemical composition. With increasing doses of fertilizers the concentrations of total nitrogen and nitrate nitrogen in the leachate were increased. The concentration of nitrogen in the leachate from the soil fertilized by nitrate was much greater than in compost with equivalent dose of nitrogen. Not only nitrates but also nitrogen from soluble organic compounds were rinsed from the soil. In the case of soil fertilized by compost the participation of nitrates in the total value of nitorgen in the leachate was 41-77%. However in the case of fertilization by ammonium sulphate this proportion was significantly higher and was in the range 60-95%. Over the years, a systematic soil fertilization by both ways increased the nitrogen concentrations in leachate. It shows that in the soil there is surplus of nitrogen, increasing during the time. |
