Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 2), R. Braun, D. Bremer

Kansas Agricultural Experiment Station Research Reports

This study was conducted from 2013–2016 to determine how irrigation and N fertilization may be managed to reduce N₂O emissions and enhance carbon sequestration. In this study, annual nitrous oxide (N₂O) emissions were greatest in urea and the least in unfertilized (no N) among treatments. During summer, the lower irrigation treatment resulted in less N₂O emitted. All fertilizer and irrigation treatments maintained acceptable quality and high levels of percent green cover; however, the controlled-release fertilizer resulted in more consistent turf quality and green cover compared to urea and unfertilized. Urea fertilizer had higher peak …
