Abstract/Contents: | "Nitrate (NO3-) leached from golf greens has the potential to impair water quality. Dissolved organic N (DON) is also increasingly recognized as a from leached from fertilized soils. A controlled experiment was conducted to determine (i) the significance of DON in total N leaching losses under simulated golf-green profiles nad (ii) the short-term contribution of fertilizer to leaching of inorganic N forms. Various turfgrasses were grown in lysimeter columns designed to simulate a golf-green profile. Fertilizer was applied at 25 kg N ha-1 every 14 d for 55 d, and the last application was labeled with 15N. Leachates were analyzed for NO3-- N, NH4+-N and DON. The 15N recovery was assessed in plant, soil, and leachates. In the presence of plants, 10 to 70% (average 40%) of total N leached was accounted for by DON. Application of 15N revealed that one-half to two-thirds of NO3-N leached in the following 14 d was derived from the fertilizer, whereas the majority of leached DON was derived from soil residual N. Nevertheless, DO15N was present in most leachate samples collected for 14 d after fertilizer application, indicating that only a few days were required to convert mineral fertilizer to leachable organic forms. We conclude that DON may be a significant component of total N leaching losses from putting greens and would account for part of the N losses traditionally attributed to volatilization and denitrification." |
