Abstract/Contents:"A reasonable fertilization plan requires understanding the supply of nitrogen (N) from soil. While modern fertilization recommendations rarely include soil analysis as a component of potential N supply. In this study, we tested the feasibility of using soil CO2 burst to estimate soil N supply on sand-based putting green soil, and whether it can be useful to turfgrass managers for making more precise N application decisions. The objectives were to 1) Investigate the correlation between soil CO2 burst with turfgrass growth and N uptake; 2) Observe the short- and long-term change of soil CO2 burst on sand-based putting green soil; 3) Whether varying N fertilizer rates affect the soil CO2 burst. The field experiment was conducted on four research greens with soil organic matter content of 0.9%, 0.6%, 0.4% and 1.0% respectively. Three N fertilization rates were applied including 0, 10, 20 kg ha-1 biweekly. Soil samples were collected at 0-10 cm depth every three weeks from May to October 2020, 2021 at the University of Wisconsin-Madison turfgrass research facility, Madison WI, USA. Soil respiration was estimated with the flush of CO2 following rewetting of dried soil (1-day incubation at ≅50% water-filled pore space and 25°C). The result has shown that soil CO2 burst was affected by soil organic matter contents but not N fertilization. While soil CO2 burst had a weak correlation with creeping bentgrass clipping production (R2 = 0.13 to 0.26), and no correlation with bentgrass N uptake. Moreover, air temperature in the field negatively affected soil CO2 burst (R2 = 0.50 to 0.57), this could be explained that when the laboratory incubation temperature was higher than the temperature in the field, the microbial activity would be boosted. Overall, soil CO2 burst cannot be solely used to make estimate creeping bentgrass growth response on sand-based putting green soil."
