| Abstract/Contents: | "Two experiments were conducted to evaluate clipping N and inorganic soil N concentrations in response to application of nitrogen fertilizer to perennial ryegrass (Lolium perenne L.) from April through November. In the first experiment, and individual plot was fertilized in one month only. In the second experiment, a plot received repeated monthly fertilization from April up until the time of sampling. At the designated sampling times, clipping and soil samples were analyzed for total nitrogen and inorganic nitrogen concentrations, respectively. Both fertilized and unfertilized turf had higher clipping N concentrations in the late fall (October and/or November) than in other months, indicating that plant uptake and transport of N was still occurring. April, June, and October fertilization yeilded the most consistent response for increased clipping N concentration. Repeated monthly fertilizer applications at a rate of 49 kg N ha-1 did not promote efficient use of fertilizer N. Lower rates or decreased frequency should be used. Inorganic soil N was highest in the fall and spring, and lower during the summer months. High clipping N and soil inorganic N in the late fall indicate that although turfgrass can utilize N at this time, uptake may not keep up with mineralization and nitrification in the soil. When fertilizer was applied repeatedly at monthly intervals, nitrate-N rapidly accumulated in the soil in the late fall. Excess accumulation of soil inorganic N could result in increased potential for nitrate leaching. Natural soil N cycles should be considered when making fertilization decisions." |
