The objective of this project was to evaluate the microbial diversity of bentgrass (Agrostis 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, washed of attached mix and diluted with 0.1% Na4P2O7 with 1% glycerol. Sampling was performed for three years. Standard dilution plating techniques were used to evaluate populations of fluorescent pseudomonads, gram-positive bacteria, gram-negative bacteria, 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." Language: English References: 0 See Also: See also related booklet, 2000, R=215446.
