| Abstract/Contents: | "Environmental concerns about nitrogen applications to turfgrass have stimulated research to quantify the amounts of fertilizer nitrogen taken up by the plant and lost from the system. Research was conducted to determine nitrogen allocation among the top-growth, roots, thatch, and soil of Kentucky bluegrass (Poa pratensis L.) and tall fescue (Festuca arundinacea Schreb.). To facilitate identification of fertilizer nitrogen, double-labeled ammonium nitrate with 5% 15N enrichment was applied at 24 and 49 kg N ha-1. The research was conducted near Mead, Nebraska on a Tomek silty clay loam soil (fine montmorillonitic, mesic Typic Argiudoll). The thatch layer and soil accounted for the largest percent of nitrogen recovered from fertilizer. The average percent of nitrogen recovered from fertilizer in the thatch and soil was 37 and 42%, respectively. The amount of applied nitrogen recovered in the top-growth at the 49 kg N ha-1 rate was greater initially, but over time declined more rapidly than the amount recovered at the 24 kg N ha-1 rate. Total nitrogen recovery in the turf system at the 24 and 49 kg N ha-1 rates was 95 and 73% of applied nitrogen, respectively. This research indicates that the majority of applied nitrogen is either retained in the soil or taken up by the turf." |
