Abstract: Percolation basin and field experiment were conducted to study on the effects of soil nitrate migration of different kinds of slow-release fertilizers in tall-fescue lawns soil and select more environment-friendly new fertilizer. Results showed that, compared with urea treatment, slow-release nitrogen fertilizer treatments could reduce nitrate nitrogen content and leaching solution. Compared with PCU30 and IU treatments, the PCU60 treatment became more efficient to reduce nitrate content and leaching amount in 0-90 cm soil layer. In summary, slow-release nitrogen fertilizer, which could reduce soil nitrate content and leaching losses, was a kind of novel fertilizer with high environmental benefit and promising application.
