| 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 diameter circular plots were randomly selected for conducting the experiment. The greens were sampled 7 times from August, 1998 to August, 1999. Data collected from each plot included turf quality index, $CO_2$ content, and physical properties of the rooting mixtures. Turf quality declined drastically when $CO_2$ content in rhizosphere increased to $5;to;6{mu}LL^{-1}$ 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. |
