| Abstract/Contents: | "The objective of this project is to determine whether modern management practices provide adequate prevention of nitrogen leaching while maintaining the high level of playability required on modern golf facilities. The unique research site at the floating 14th green at the Coeur d'Alene Resort Golf Course allows for complete collection of leachate from the green surface due to its self-contained design. This permits an accurate determination of concentration and quantity of leachate. An automated flow meter with a sampler line are located in a storage tank beneath the green surface. As water is leached through the soil profile and collected by the drain lines located within the green, the flow meter monitors flow rate and total flow. Every 24 hours, a leachate sample is automatically taken from the drainage water prior to its entering the storage tank. The leachate sample is then stored within the refrigerated sampler until removal for analysis. Currently a soluble 20-0-20 fertilizer is being applied at 0.1 lb N/1000 ft2 every 7 to 10 days throughout the growing season. For research purposes, N rate was briefly increased to 0.3 and 0.6 lb N/1000 ft2 to observe the leachability of higher rates of fertilizer. Future objectives include the use of a granular fertilizer to observe the effect of form on nitrate and ammonia leaching. Leachate data to date indicates very low concentrations of ammonia and nitrate. Nitrate levels range from 0.11 to 3.97 ppm, well below the EPA limit of 10 ppm (Fig. 1). Ammonia levels ranged from 0.12 to 0.87 ppm (Fig. 1). Following closure of the green to play in November 1998, six micro-lysimeters were placed in the rootzone to allow for additional sampling. To develop nitrogen balance, soil and clipping samples are being taken to determine the concentration and form of N present. Clipping samples are taken from daily mowing, weighed, sub-sampled, then frozen for later analysis. Currently clipping samples range from 3.3 and 6.1% N on a oven dry weight basis. (Fig 2.) Future research includes the formation of a nitrogen balance. In addition, construction of a water balance can be made leading to a better understanding of water use efficiency in the turfgrass environment. The findings of the project will provide a clearer understanding of how golf course management practices affect the environment. It will allow the public to directly view how management practices on sand-based greens affects groundwater and the environment. It will demonstrate to the public the high level of effort being placed on insuring that the environment is preserved through current golf course practices." |
