| Abstract/Contents: | "Increasing carbon dioxide (CO2) concentrations have contributed to global climate change. Atmospheric CO2 concentration has increased by 43%, from 280 ppmv in 1850 to 400 ppmv in 2015. This increase is expected to alter the distribution of C among the atmosphere, vegetation, and soils. Despite its large-scale presence in the urban ecosystem, the role of turfgrasses in C cycling has received limited attention, and studies with warm-season turfgrasses are lacking. The objective of this study was to estimate CO2 flux from soil as affected by N applied to bermudagrass [Cynodon dactylon (L.) Pers. C. transvaalensis Burtt Davy]. The study was initiated in March 2012 on 8-yr-old Tifway hybrid bermudagrass plots located at the Auburn University Turfgrass Research Unit on a Marvyn loamy (fine-loamy, kaolinitic, thermic Typic Kanhapludult) sand soil. The experimental design was a randomized complete block with four N rates of 24, 49, 98, and 196 kg N ha-1 yr-1 that were replicated three times. Carbon dioxide flux was measured weekly for 95 wk using an automated soil CO2 flux system (LiCor LI-8100A, LICOR, Inc., Lincoln, NE). Soil temperature and moisture were also determined during CO2 flux measurements. Results showed strong correlation between CO2 flux and N rate (r2 = 0.99**). Accumulated CO2 flux increased by 35%, from 107 to 144 Mg ha-1 as N rate increased from 24 to 196 kg N ha-1, respectively. Data suggest that a lower N application rate may be a better choice for mitigation of CO2 emissions under bermudagrass management." |
