| Abstract/Contents: | "Kentucky bluegrass (Poa pratensis L.) lawns generally require N fertilizer at 98 to 196 kg/ha/year to maximize appearance and growth. Most homeowners do not regularly fertilize, resulting in weed- and disease-prone lawns due to insufficient N. This two-year field study evaluated three urea-based N sources: urea, sulfur-coated urea (SCU), and polymer-coated urea (PCU) at N rates of 0, 49, or 147 kg/ha/year applied in early September only or 49 kg/ha/month from September through November. Mean turfgrass quality, canopy greenness, and total dry matter yield all increased with annual N rate. All fertilizer treatments, except the September-only SCU treatment at 49 kg of N per ha, produced more dry matter yield than the unfertilized control. The highest mean quality and greenest turf resulted from three consecutive applications of urea at the N rate of 49 kg/ha/month and single September-only PCU or SCU applications at the 147-kg/ha/year N rate. There was no advantage to monthly urea, PCU, or SCU applications when compared to September-only SCU or PCU applications of N at 147 kg/ha. These results demonstrate that homeowners can produce a high quality bluegrass turf with less effort by applying SCU or PCU in September only at N rates of 147 kg/ha." |
