Abstract/Contents:"Field experiments were conducted to study the effects of two kinds of macromolecule polymer coated urea that the nitrogen release period were 30 and 60 days (PCU30, PCU60), sulfur coated urea (SCU), urea mixed with nitrification inhibitor (UI) and urea (U) on grass growth, nitrogen uptake, ammonia and N2O volatilization of fertilizer in tall fescue turf. Results showed that application of fertilizer such as PCU30, PCU60, SCU in spring and autumn at total rate of 260 kg/hm2 per year could meet nitrogen requirement of grass normal growth. Meanwhile, the clipping yields and nitrogen uptake of those treatments were all significantly higher than U treatment at same N rate in one year with four times application. In terms of gaseous nitrogen loss, ammonia volatilization from UI was 44.42 kg/hm2, which was significantly higher than other treatments. But N2O emission of this treatment was 6.46 kg/hm2, significantly lower than others. The ammonia volatilization of PCU30, PCU60 and SCU treatments were 17.67, 13.59 and 18.54 kg/hm2 and the N2O emissions were 8.14, 6.92 and 9.91 kg/hm2 respectively. But all of them were significantly lower than the U treatment. Considering integrated factors, PCU60 should be taken as a suitable fertilizer on tall turf grass with twice application in spring and autumn for a year, which could increase nitrogen use efficiency and reduce nitrogen volatilization, showing an outstanding ecological and environmental benefit."
