Abstract/Contents:"Criticisms of the environmental impacts of lawns, including a high climate footprint, pose challenges to the market acceptance of natural turfgrass. Mowing is the minimum requirement for maintaining a uniform lawn, however the fuel emission of mowing is considered the major component of the hidden carbon cost. The goal of this study is to evaluate the effects of mowing height and mowing frequency on CO2 assimilation, ecosystem respiration, and clipping production. A portable clear chamber with a CO2 gas analyzer is used to measure CO2 exchange every two weeks on a subset of treatments from an Oregon School IPM field trial with mixed species of cool-season turfgrasses at year 4 post-establishment. The mowing treatments evaluated are mowing heights of 5 cm weekly and monthly and 10 cm weekly. To date, turfgrass net ecosystem CO2 exchange rate varied by season with higher rates observed during cool months. Ecosystem respiration releases CO2 to the atmosphere, which can substantially offset the CO2 assimilated by the photosynthesis of turfgrass."
