| Abstract/Contents: | "Urban ecosystems are rapidly expanding and their effects on atmospheric nitrous oxide (N2O) inventories are unknown. Our objectives were to: (i) measure the magnitude, seasonal patterns, and annual emissions of N2O in turfgrass; (ii) evaluate effects of fertilization with a high and low rate of urea N; and (iii) evaluate effects of urea and ammonium sulfate on N2O emissions in turfgrass. Nitrogen fertilizers were applied to turfgrass: (i) urea, high rate (UH; 250 kg N ha-1 yr-1); (ii) urea, low rate (UL; 50 kg N ha-1 yr-1); and (iii) ammonium sulfate, high rate (AS; 250 kg N ha-1 y-1); high N rates were applied in five split applications. Soil fluxes of N2O were measured weekly for 1 yr using static surface chambers and analyzing N2O by gas chromatography. Fluxes of N2O ranged from -22 μg N2O-N m-2 h-1 during winter to 407 μg N2O-N m-2 h-1 after fall fertilization. Nitrogen fertilization increased N2O emissions by up to 15 times within 3 d, although the amount of increase differed after each fertilization. Increases were greater when significant precipitation occured within 3 d after fertilization. Cumulative annual emissions of N2O-N were 1.65 kg ha-1 in UH, 1.60 kg ha-1 in AS, and 1.01 kg ha-1 in UL. Thus, annual N2O emissions increased 63% in turfgrass fertilized at the high compared with the low rate of urea, but no significant effects were observed between the two fertilizer types. Results suggest that N fertilization rates may be managed to mitigate N2O emissions in turfgrass ecosystems." |
