| Abstract/Contents: | "A creeping bentgrass (cv Penncross) stand was established by seed (1.5 lb/1000 sq ft) in July 1993 and maintained at 0.5 inch mowing height. At the beginning of the trial, the baseline soil pH was 5.8, 3% organic matter 14 lbs/A P and 40 lbs/A K. Soil fertility will be measured in Spring 1995 after one full year of treatment application. The number of fluorescent pseudomonad bacteria ranged from 40,000 to 100,000 CFU (colony-forming units- usually single cells) per gram of soil. The number of total actinomycetes ranged from 320,000 to 650,000 per gram of soil and the number of streptomyces-type actinomycetes ranged from 80,000 t0 400,000 CFU per gram of soil. Although a range of populations was observed among the treatments, the numbers are not significantly different due to high variation. This variation is commonly encountered when measuring soil microbial populations because their numbers fluctuate rapidly in soil. There was a trend in higher overall populatios in the Par-Ex treatment, followed by All-Gro until a new supply of the All-Gro product arrived in mid-season. The number of dollar spot infection sites were similar among the fertilizer treatments. There was no difference between the incidence of disease between the organic fertilizers and the inorganic or combination N sources." |
