Abstract/Contents:Presents a long term study initiated during 2003 to "(1) determine nitrate-nitrogen and phosphorus leaching from a turfgrass stand that has been continually fertilized for 20 years," and "(2) continue data collection from the Long-Term Nutrient Fate Research Area at MSU [Michigan State University]." Notes that data have, as of 2010, been collected for 12 consecutive years. Details methods and materials used during the experiment, stating that "from July 1998 through 2002, lysimeters were treated annually with urea at a low N [nitrogen] rate of 98 kg N/ha [kilograms N per hectare] (24.5 kg N/ha per application) and a high N rate of 245 kg N/ha (49 kg N/ha per application)." Reports that "from 2004 to 2009, for the high N rate, less than 4% [percent] of all samples had NO3-N [nitrate] concentrations greater than 20 mg/L [milligrams per liter]." Concludes that "results continue to indicate low amounts of phosphorus leaching."

USGA Summary Points:From 2004 to 2009, for the high N rate, less than 4% of all samples had NO3-N concentrations greater than 20 mg/L. For the high N rate, most of the sampling dates that had elevated NO3-N concentrations were during late fall or winter when the turfgrass was dormant. For the low N rate, the mean NO3-N concentration has been 5 mg/L or less for every year except one (2003). Results continue to indicate low amounts of phosphorus leaching.
