Abstract/Contents:Presents a study conducted to determine "whether or not after an extended period of time, 10 years, will the amount of nitrate-nitrogen leaching from a turfgrass system change." Details the methods and materials used in the study, stating that "between 1989 and 1991 at the Hancock Turfgrass Research Center, Michigan State University [in East Lansing, Michigan], four monolith lysimeters were constructed." Reports that for 2000-2002 "the average total labeled N [nitrogen] recovery among turfgrass clippings, verdure, thatch, soil, and roots for the low and high N rates was 78 and 74% respectively. Over approximately two years, 1 and 11% of labeled fertilizer-N was recovered in leachate for the low and high N rates, respectively." Also reports that "leachate analysis for 2003 indicates that NO3-N concentrations for the high nitrogen rate have not declined from previous levels and there has been only a slight elevation in NO3-N concentration for the low nitrogen rate." Concludes that "these results indicate that total yearly applications of 245 kg [kilogram] N ha-1 in the form of urea to a 10 + year old Kentucky bluegrass stand with monolith lysimeters in place, resulted in elevated levels of NO3-N in leachate."
