| Abstract/Contents: | "Conducted in cooperation with Clemson University (H. D. Skipper) and the University of Florida (M. L. Elliott) this study evaluates bacterial species and their population fluxes in the soil and rhizosphere during the establishment and maintenance of putting greens. Treatments in this study include grass type (bent or bermuda), organic construction material (Reed peat moss vs. sphagnum), fumigants (methyl bromide, metam sodium or dazomet) and N fertility regimes (1/10 or 1/5 lb N/1,000 ft2/week). At Auburn University treatments are N rate and construction materials (100% sand or 80/20 sand/peat). Sixteen containerized greens were constructed at the Auburn University Turfgrass Research Unit, four replications of each fertility/soil mix combination. Each green is 1 m long and 0.5 m wide, and each drains to an individual leachate collection chamber. Total leachate is collected from each green each week (or as=needed), and a subsample collected for NO3-N and NH4-N analysis. In February, May, August and November of each year root and soil samples (0-4 in. depth) are collected from each green. An additional soil sample is also collected for NO3-N and NH4-N analysis. Root samples are shipped to the Univ. of Florida where they are subjected to dilution plating and identification. Selected isolates are returned to Auburn Univ., where identification at the species level is conducted via GC FAME analysis. Results of 3 years of leachate collection have revealed that, once grow-in and application of higher rates of N was completed (a rate of 1 or 2 lb N/1,000 ft2/month) was used for the first three months of the study) little NO3-N or NH4-N leaches through the rooting profile of the putting greens. During the past two years no more than 2 ug NO3-N/ml of leachate has been collected at any one sampling, indicating the frequent application of low rates of N has maintained quality turf and reduced NO3-N leaching. Preliminary evaluation of 8 dilution platings (from Univ. FL data) indicates that populations of selected bacterial species were affected by both N rate and putting green mix. There were no strong trends in bacterial populations over time." |
