Abstract/Contents:"Effective management of turf on high sand base profiles requires sound knowledge of the turf-soil relationship and rhizosphere microbiology. The objective of this investigation was to assess soil microbial community function and turf quality in response to bio-stimulant treatments. The study was conducted on a 2-year old constructed sand green, an amended sandy loam green, and a 6-week old constructed sand-based green at Werribee Park Golf Club and Patterson River Country Club outside Melbourne, Australia. The experiment was established as a randomised complete block design of seven treatments (Kelpak ®, Kelpak ® + Molasses, Essential ®, Carbo-Aid ®, Aminogro ®, and Supa Humus ®, applied at recommended rates, and an untreated control), replicated four times on each green. Composite soil samples from each plot were collected on three dates in March/April 2003. Turfgrass quality was determined visually the National Turf Evaluation Program scale (1-9). Microbial community profiles were assessed using BIOLOG™ technology to determine a metabolic fingerprint of carbon substrate utilisation. Results showed significant differences in metabolic profiles between the Patterson River site and Werribee Park; the soil-based greens at Werribee Park showed a higher level of substrate utilization than the new sand-based green at Patterson River. During the short term of this study there were no within-site significant differences observed between treatments on the microbial community parameters that were measured. At Patterson River the treatments did result in significantly enhanced turf quality relative to the control at the first post-treatment assessment. This effect is likely a function of stress reduction during the initial traffic period on the putting green. These data are consistent with previous observation of microbial community function in sand versus soil, and the use of carbon utilization profiles to discriminate microbial communities and their response to current management regimes."
