| Abstract/Contents: | "Sports field constructed on sandbased root zones are generally permeable to water and nutrients, and potential contaminants of the groundwater. This study was conducted to determine the effect of slow-release and water-soluble fertilizers on growth, nutrient uptake and leaching from a sandbased Kentucky bluegrass (Poa pratensis L.) turf. Two root zone mixtures and two N rates were investigated in two independent lysimeter experiments. In the first experiment (I) the 80:20 sand-peat mixture gave better growth and darker colored turf than the 60:40 sand-peat mixture. Only resin coated NPK and water-soluble NPK treatments in this experiment gave acceptable turf quality for the entire growing-season. Frequent application with water-soluble fertilizer or spring application with slow-release carriers gave generally <5 mg l⁻¹ NO₃-N in the leachate. In the second experiment (II) application of 300 or 450 kg N ha ⁻¹ (either as spring or spring/summer application) as urea-ammonium-nitrate (emulsion) did not give desirable turf growth during the entire period of investigation. Sulfur-coated urea gave generally better turf quality than UAN, but not as good as biweekly compound NPK fertilization. Irrespective of fertilizer N rate, the leaching losses of N varied from 1.1 to 2.9%, giving average NO₃-N concentrations in the leachate for all treatments <2 mg l⁻¹. Sandy soil used for sports turf, and fertilized with SCU and resin coated NPK, or frequent and small amounts of water-soluble N carriers, appears not to create any serious environmental concern in the southern part of Norway where the rainfall is moderate." |
