| Abstract/Contents: | "The use of sandy rooting media with rapid infiltration rates in the construction of golf greens provides the potential for N pollution of nearby water supplies. This study was designed to measure the effects of different N sources on NO3- and NH4+ concentrations in leachate and runoff from golf greens constructed with various rooting media. Individual golf greens with USGA-type profiles were constructed in the field with upper 30 cm layers consisting of sand-peat, sand-soil-peat and sandy loam soil mixtures. All profiles were equipped with subsurface tile drains over a plastic sheet and were treateed sequentially with the following N fertilizers: NH4NO4, urea formaldehyde, 12-12-12, Milorganite, and IBDU. Leachate and runoff were collected and analyzed for NO3- and NH4+. Nitrate concentrations in leachate from sand, mixed, and soil greens fertilized with quick release materials ranged from 45 to 326, 8 to 170 mg liter-1, respectively and remained in this range for a 3-week period. Runoff concentrations from the greens constructed of sandy loam soil exceeded 30 mg liter-1. No runoff was collected from sand or mixed greens. Nitrate N losses from various sources were in the order of NH4NO3 > 12-12-12 > Milorganite > Isobutylenediurea (IBDU) > Urea formaldehyde. Isobutylenediurea provided a very uniform release rate. Milorganite had a 25 to 30 day delay before NO3- appeared in the leachate. Soluble sources, NH4NO3, and 12-12-12 exhibited leaching within 5 days after application. It appears that regular moderate applications of slow release N sources would provide minimum NO3-, loss while supplying a continuous N supply. Ammonium losses ranked from greatest to smallest were NH4NO3 > Urea formaldehyde > Milorganite > 12-12-12 > IBDU. Ammonium losses contributed very little to the total N losses from golf greens. Highest total N loss was 23% of the applied N." |
