Contamination of Nitrogen-containing Fertilizers to Environment and Vegetable and Rational Regulation and Control Measures |
| |
| Abstract: | The application of nitrogen containing fertilizers in agriculture plays an important role in ensuring food-supplying safety in China. However, excessive application of N fertilizers will pollute the environment and edible vegetables. This paper focused on reviewing the pollution of nitrogen containing fertilizers to surface and ground waters, atmosphere and vegetables. Rational regulation and control routes were proposed, such as: Making recommendation of nitrogen-containing fertilizer rates based on nitrate contents in the soil rooting layers; (2) improving crop varieties; (3) developing appropriate controlled availability fertilizers; and (4) adopting soil conservation techniques. |
