The carbon sequestration potential of three common turfgrasses : Lolium perenne; Fescue rubra; and Poa pratensis

University of British Columbia. Campus and Community Planning

The objective of this study was to study the effect of trimming on different species of turfgrass and on their clippings as well as to find out which species has the greatest carbon sequestration ability. In the short term, clipping of the grasses results in an immediate decrease in net photosynthesis rate followed by an increase after 24 hours. Over the long term, uncut grasses decline in photosynthetic ability, most likely a result of physiological changes as grass blades age. Clippings from the grasses experienced an immediate decrease in photosynthesis followed by negative net photosynthesis at 4 hours before decreasing to approximately no net photosynthesis at the end of 24 hours. The carbon sequestration ability of these turfgrass species depends on their age and the time after mowing.
