Abstract/Contents:Presents a study conducted "to assess the relationship between several N [nitrogen]-sources, biomass production and turf quality." Details methods and materials used in the study, stating that "six N sources were compared on plots of a cool-season grass mixture: Lolium perenne (perennial ryegrass), cultivars 'Bardorio', 'Barsunny' and 'Adeline', 50% Poa pratensis (Kentucky bluegrass), cultivar 'Barimpala', 50% sown at 25 g [grams] m-2 [per square meter]. These included a Fast Release Fertilizer - Ammonium Nitrate - AN (26-0-0)...Slow Release Fertilizers: Isobutylene Diurea - IBDU (32-0-0)...Sulphur coated Urea - SCU (15-5-7)...Ammonium Sulphate with Nitrification Inhibitor - ASNI (26-0-0)...and Methylen Urea - MU (39-0-0)...Control Release Fertilizer - Polymer Coated Urea at 2 months longevity - PCU2 (41-0-0). Test plots with no N input were included." Reports that "biomass production is clearly influenced by the N-source...There were significant differences between MU, IBDU and PCU2. SCU, ASNI and AN are in the same statistical group and produce the greatest biomass, while PCU2, IBDU and MU are in different statistical groups, producing a significantly lower quantity of biomass." Concludes that "biomass production under the different N treatments shows a wide range of results. The relationship between turf quality and biomass production has been verified. It seems possible, for amenity turfgrasses, to achieve a good turf quality whilst reducing dramatically the green biomass produced in the active growing season, by means of an informed choice of the N sources."
