Abstract/Contents: | "This trial was established using 'Penncross' bentgrass grown on sand, sand+peat, sand+coconut coir and sand+zeolite. Additional treatments superimposed on the main plots included organic vs. inorganic nitrogen and supplemental carbohydrate vs. no carbohydrate. Plots were evaluated for quality using the NTEP (1-9) scale during 1998. Microbial community analysis using the Biologā¢ microplate system was carried out on samples taken in November 1997, January, February, March and July 1998. Low nitrogen fertility during the establishment year likely contributed to the slow establishment , lower quality levels and incidence of Take-All patch disease. In spite of these defects, quality differences were observed in response to both nitrogen and carbon fertility. The microbial communtiy analyses showed a minor impact of amendment on some community parameters - amendment effects were likely most sensitive to the lower nitrogen fertility levels. Both carbon and nitrogen fertility influenced community parameters. Total activity (absorbance) and substrate diversity appeared to respond to better nitrogen fertility and to the presence of supplemental carbon. No main plot amendment effects were detected in the microbial community measurements. It is interesting to note that of the numerous effects noted in the trial to date, there wre no significant interaction effects between any of the treatments. This lack of interaction is further evidence that the lower nitrogen fertility levels may have masked the potential for clearcut definition of treatment effects and interactions. While these results do not portray a clear picture of the microbial community changes, the observed responses to nitrogen and carbon fertility suggest trends that deserve further attention under fertility regimes modified to ensure an improved turfgrass growth response." |
