To investigate the utility of Vulpia myuros (L.) C. C. Gmel. and Paspalum notatum Flügge. beyond effective functions as partner plants in fruit growing on carbon fixation against global warming, we developed a simple measurement system equipped with solid electrolyte CO2 sensors, an A/D converter and a personal computer. Consequently, this system was very useful for the continuous measurements of CO2 concentration in the air surrounding V. myuros and P. notatum and their photosynthetic CO2 assimilation rates. Furthermore, the ratio of contribution of CO2 assimilation per day to plant biomass (dry weight) in clear weather was 0.011% in V. myuros and 0.005% in P. notatum. In addition, carbon fixation by V. myuros and P. notatum was estimated at 6.854 ton C (carbon)/ha for 3 months and 17.256 ton C/ha for 4 months in vigorous growth season, respectively. These results indicate that the introduction of sod culture system using V. myuros and P. notatum into fruit growing will be very effective in reducing CO2 in the air.
