골프장 putting green 근권(根圈)에서의 이산화탄소(CO₂)함유량

다국어 초록 (Multilingual Abstract)

Anaerobic soils Emit 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 CO₂content 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, CO₂content, and physical properties of the rooting mixtures. Turf quality declined drastically when CO₂content in rhizosphere increased to 5 to 6μLL-¹during the late summer season. The CO₂content increased as water content in the root zone increased, but was inversely related to infiltration rate. Cultivation of a golf green may reduce CO₂content in the rhizosphere, but the benefit of cultivation decreased with time.
