Anaerobic soils limit the amount of free oxygen available in the rhizosphere, and therefore will impede grass root development and restrain nutrient availability for turf growth. An in situ study was conducted on existing greens to investigate the relationship between CO 2 content in the rhizosphere and turf quality. Nine greens were selected in the study. On each green, five 1‐m‐diam. circular plots were randomly selected for conducting the experiment. The greens were sampled seven times from August 1998 to August 1999. Data collected from each plot included turf quality index (TQI), CO 2 content, and physical properties of the rooting mixtures. Turf quality declined drastically when CO 2 content in the rhizosphere increased to 5 to 6 μL L −1 during the late summer season. The CO 2 content increased as water content in the root zone increased, but was inversely related to infiltration rate. Cultivation of a golf green may reduce CO 2 content in the rhizosphere, but the benefit of cultivation decreased with time.
