Abstract/Contents:"Various chemicals and nutrients are widely used by the turfgrass industry to maintain a high quality stand of turf. Runoff and leaching of fertilizers and pesticides from golf courses, recreational, agricultural, municipal, and industrial operations are perceived to be an important environmental problem. In this study, we are trying to answer the following question. How much of the nitrogen, phosphorous, Trimec (registered), Pendimethalin, Isazophos, Chlorpyrifos, Metalaxyl, and Chlorothanolil applied to a turf area maintained as a golf course fairway move past the root system to the groundwater? This three-year research project is being funded by the United State [States] Golf Association (USGA). For the first year of the project, the fate of nitrogen and phosphorous will be studied. The soil that was used was excavated from the Horticulture Farm with an established stand of turf cut at fairway height. Undisturbed soil columns were brought into the greenhouse in November, 1990, and testing started in February, 1991. The one-week testing procedure starts with applying nitrogen and phosphorous in a liquid form to the turf. The source of nitrogen is urea and for phosphorous, calcium phosphate was used. To distinguish between nitrogen that is stored in the soil and nitrogen that is applied, the urea is labeled 15[superscript]N which is only present in extremely low levels in nature. To determing the effects of irrigation rates, two watering schemes were used. One is an application of 1 inch immediately after nutrients are applied and the other is 4 separate quarter inch applications distributed throughout the one week test period. Volatilizing nitrogen and any soil water that leaches through the column is collected and tested for nutrients at the end of the test period, and the soil and vegetative materials are dried and sent to the analytical lab for testing. The following figure is a diagram showing the method of collecting volatilized nitrogen and soil water leachate."
