Abstract/Contents:"Seventeen nitrogen fertilizers were evaluated for their effects on established Kentucky Bluegrass at Olds, Alberta in 1995. The fertilizers included a) slow release synthetics, b) quick release synthetics c) slow and quik release synthetic mixtures and d) organics from biological sources. Response to the applications was measured in terms of increased vegetative growth, colour improvement and turf density. All fertilizers were applied at a rate of 0.5 kg/100m² of actual nitrogen. Two applications were made during the growing season. Every fertilizer treatment improved growth over the untreated checkplot in each of the three categories measured. There was a large range of effectiveness between products. Some of the synthetic slow release fertilizers were superior to other formulations in each of the categories measured. These included a polymer coated urea, a polymer/sulphur coated urea and a methylene urea. Other slow release synthetics and slow/quick release synthetic mixtures were somewhat lees effective. The urea treatment performed better than many of the specialty products."
