Abstract/Contents:"Carbon dioxide (CO2), a greenhouse gas related to global warming, has increased in concentration during the last 200 years. Therefore, the study of the Soil Organic Carbon (SOC) dynamics and carbon sequestration capacity in several systems has attracted a rising interest. Turf grass, the main vegetation system in the urban and suburban environment in central Chile can play an important role in carbon sequestration to the soil, through photosynthesis. The objective of this project is to assess and compare the extent of Soil Organic Carbon (SOC) sequestration of different pure species and mixes of managed turf grass versus bare soil in central Chile, and to correlate these values with the photosynthetic capacity of the species, assessed by means of net CO2 assimilation and fluorescence determinations throughout the year. 23 single species and mixes of cold (C3) and warm (C4) season turf grasses used in urban settings in Chile were randomly established in 0.9 x 2.4 m plots, using a complete randomized block design with three replications; in Pirque, Chile. Soil samples were taken seasonally at 30 cm deep, and divided into three sections: 0 to 10 cm, 10 to 20 cm and 20 to 30 cm. Each section was oven dry and grounded, previous SOC and organic matter (OM) determination by means of Loss on Ignition and dichromate digestion (modified Mebius method), respectively. Additionally, et CO2 assimilation (of the aerial part) was measured using an IRGA and photochemical yield of PSII centre using a modulated fluorimeter. Our results indicate clear differences on SOC and OM between pure species, explained by its average capacity for CO2 fixation and resistance to photo inhibition throughout the year. Even though, summer time photosynthetic capacity of the C4 species is significantly higher than that of C3 species, the latter maintains CO2 assimilation through autumn and winter and, very likely, are capable of higher carbon sequestration, particularly Festuca arundinacea. Research dealing with measuring carbon pools in turf grass systems grown in Chile will help to understand the role of turf grass in contributing to terrestrial carbon sequestration. *Project 3110146 funded by the National Commission for Scientific and Technological Research - CONICYT, Chile"
