| Abstract/Contents: | "Microbial diversity in constructed and fumigated golf course putting greens is a topic that has not been widely explored. The objective of this project was to evaluate the microbial diversity of bentgrass (Agrostris palustris 'Crenshaw') greens over time as affected by root-zone mix and N rate. Two root-zone mixes (80/20% sand/peat and 100% sand) and two N rates (1.0 and 0.5 g N m-2 week-1) were evaluated, with four reps of each root-zone/N rate treatment built in individual separated mini greens (1 m x ½ m). Quarterly (Feb., May, Aug., Nov.) 0-7.6 cm root samples were removed from each mini-green. Sampling was performed for three years. Standard dilution plating techniques were used to evaluate populations of fluorescent pseudomonads, gram-positive bacteria, gram-negative bacteria, S. maltophilia-like bacteria, actinomycetes and heat-tolerant bacteria. There was rarely a significant N rate x root-zone mix interaction, although main effects of N rate and root-zone mix did affect microbial diversity at some samplings. If differences did exist, bacterial counts were higher in the sand/peat root zone mix or in the treatments receiving the higher rate of N. there were no obvious population trends in any microbial population over the three year sampling period. Populations of total bacteria ranged from a low of 5.4 to a high of 8.3 log10 cfu/gram throughout the two-year sampling period." |
