| Abstract/Contents: | "Nitrate (NO3-) can leach from golf greens, potentially causing the degradation of surface and ground water quality. A greenhouse experiment was conducted with 11 annual bluegrass (Poa annua var. reptans Hausskn.) ecotypes from eastern Canada (Quebec and Ontario) and the USA, and three bentgrass (agrostis spp.) species to compare N uptake and potential for N leaching. Two-month-old grasses were established for a 6-wk period in lysimeter columns simulating a golf-green profile. An unplanted root zone control was included. Water-soluble fertilizer was applied at 25 kg N ha-1 (NH4NO3) every 14 d for 57 d. Leachate sample were collected every second day and analyzed for NO3-N and ammonium N(NH4-N) content. Dry weight and N concentration were determined on clippings, shoots, and roots. Ammonium N leaching was negligible for all grasses. Less NO3-N leaching losses occurred under bentgrass (6-11% of applied N) than under annual bentgrass (28-71% of applied N). Differences in NO3 leaching were also found within annual bluegrass; Quebec P.annua>Ontario P.annua> USA P.annua. Grasses with a greater aboveground biomass developed a larger and deeper root system and were associated with a greater N uptake (r=0.94) and, therefore, a lower NO3-N leaching (r=-0.94). Breeding programs and management practices to improve turfgrass root development appear to be critical to reduce fertilizer N leaching under sand-based putting greens." |
