“…Comparing turfgrass sites to bare soil, Acuña E. et al [ 50 ] reported that SOC increased over a 26-month period with nine turfgrasses in Chile, whereas the SOC in bare soil decreased (likely the labile SOC pool). This is consistent with other studies reporting higher SOC in lawns compared to bare soil [ 59 , 64 ]. Lawns also have higher soil respiration rates compared to bare soil [ 55 , 59 , 64 ].…”

“…This is consistent with other studies reporting higher SOC in lawns compared to bare soil [ 59 , 64 ]. Lawns also have higher soil respiration rates compared to bare soil [ 55 , 59 , 64 ]. Soil respiration, i.e., the process of releasing CO 2 back to the atmosphere, represents a carbon loss from the plant–soil system.…”

“…Many research studies have compared turfgrass systems to adjacent ecosystems ( Table 2 ). Higher SOC values in turfgrass systems compared to native grassland systems have been reported in numerous studies [ 7 , 26 , 34 , 35 , 64 ]. Moreover, lawns often have higher SOC values than agricultural soils [ 34 , 35 , 64 , 69 ], with the exception of one report showing similar SOC values between lawns and corn fields [ 66 ].…”

“…Nevertheless, soil respiration is an important process for soil nutrient cycling and can serve as an indicator of microbial activities. Soil respiration from turfgrass systems was reported to be higher than that from bare soil [ 55 , 59 , 64 ], gravel mulch [ 65 ], and agricultural soils [ 35 , 64 , 66 ], indicating relatively higher microbial activities in turfgrass soils. Soil respiration rates measured in turfgrass systems are also comparable to other natural or managed ecosystems ( Table 2 ) and were shown to be affected by soil temperature and moisture [ 29 , 59 ].…”

Plants are key components of the terrestrial ecosystem carbon cycle. Atmospheric CO2 is assimilated through photosynthesis and stored in plant biomass and in the soil. The use of turfgrass is expanding due to the increasing human population and urbanization. In this review, we summarize recent carbon sequestration research in turfgrass and compare turfgrass systems to other plant systems. The soil organic carbon (SOC) stored in turfgrass systems is comparable to that in other natural and agricultural systems. Turfgrass systems are generally carbon-neutral or carbon sinks, with the exception of intensively managed areas, such as golf course greens and athletic fields. Turfgrass used in other areas, such as golf course fairways and roughs, parks, and home lawns, has the potential to contribute to carbon sequestration if proper management practices are implemented. High management inputs can increase the biomass productivity of turfgrass but do not guarantee higher SOC compared to low management inputs. Additionally, choosing the appropriate turfgrass species that are well adapted to the local climate and tolerant to stresses can maximize CO2 assimilation and biomass productivity, although other factors, such as soil respiration, can considerably affect SOC. Future research is needed to document the complete carbon footprint, as well as to identify best management practices and appropriate turfgrass species to enhance carbon sequestration in turfgrass systems.
