| Abstract/Contents: | "Conducted in cooperation with Clemson University (H.D. Skipper) and the University of Florida (M.L. Elliot) 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 (sphagnum vs. reed sedge), fumigants (methyl bromide, metam sodium or dazomet) and N fertility regimes (x vs 2x normal). At Auburn University treatments are N rate (1x or 2x normal rate) and construction materials (pure sand putting green or 80/20 sand/peat mix). Sixteen containerized greens were constructed at the Auburn University Turfgrass Research Unit, four replications of each fertility/soil mix combination. Greens were sodded in January 1997 with washed bentgrass sod (cv 'Crenshaw'). Greens are 1 m long x 0.5 m wide, and each drains to an individual collection chamber. Total leachate from each green is collected as needed, volume recorded and a subsample is analyzed for NO3-N and NH4-N concentration. In February, May, August and November of year root and soil samples (0-4 inch depth) are collected from each green. These samples are shipped to the Univ. of Florida, where they are subject to dilution plating and identification. Selected isolates are returned to Auburn University, where identification at the species level is conducted via GC FAME analysis. Nitrogen rates applied at the Auburn University site were originally 1 or 2 lbs N/1000 ft2/month (granular fertilizer source). Excessive loss of N through leachate and burning of turf at application resulted in a shift of application times and amounts to 1/5 or 1/10 lb N/1000 ft2/week applied via a CO2 backpack sprayer. These N application rates were initiated on 25 August, 1997 and will likely continue for the rest of the study unless grass health indicates a need for more N." |
