| Abstract/Contents: | Nitrous oxide (N2O) is a natural and anthropogenic by-product associated with global climate change and potentially the most ozone-depleting gas. Turfgrass covers large areas of land in the United States, and some is fertilized with N and irrigated with the potential to emit N2O at similar rates (i.e., average of 2.7 kg N2ON ha-1 yr-1) as agricultural soils. Our objective was to review scientific literature on N2O emissions in turfgrass and identify knowledge gaps and future research needs. Few turfgrass studies exist in which fluxes were intensively measured for long enough to calculate accurate annual emissions, which have ranged from 1.01 to 7.6 kg N2O-N ha-1 yr-1 in various turf species receiving N fertilizer, and from 0.5 to 2.24 kg N2ON ha-1 yr-1 in unfertilized turf species. Research indicates reduced irrigation and controlled-release forms of N may slow nitrification and denitrification processes, and thus, reduce N2O emissions in turfgrass. Future research should be directed toward long-term investigations of controlled-release fertilizers (e.g., investigating N application amounts, seasonal application timings, and differences between warm- and cool-season turfgrass species) combined with irrigation techniques (e.g., irrigation quantity, frequency, and application timing surrounding fertilization events) to minimize N2O emissions, maximize plant nutrient uptake, and determine more efficient application methods that reduce emissions and water use in warm- and cool-season turfgrass species. The use of model simulations (i.e., DAYCENT and DNDC) should be further developed for turfgrass systems to predict long-term impacts of different management practices on C and N cycling in turfgrass." |
