Abstract/Contents:"Managed turfgrass systems receive significant amounts of fertilizer nitrogen annually and questions concerning environmental contamination remain unanswered. This study was conducted to monitor soil nitrate levels in the top 90 cm of the soil profile. Soil cores were taken seasonally from two golf course fairways in Eastern North Carolina, varying by soil series and years of managed turf. Samples were extracted and analyzed for nitrate. Site 1 was a Rimini sand under managed bermudagrass for 80 years. The highest nitrate concentration (3.5 mg kg-1) occurred in March 1999, and minimum nitrate levels (<1.4 mg kg-1) were measured during Summer 1999. Nitrate levels did not vary with depth. Nitrate concentrations at Site 2, a Norfolk loam with a 40 year stand, were greatest (5.7 mg kg-1) in March 1999 and lowest (1.6 mg kg-1) in August 1999. Nitrate levels were greatest in the top 10 cm at Site 2, but there was only 1.5 mg kg-1 difference between the 10 cm and 90 cm depth. Collectively, the data indicate that nitrate did not accumulate to high levels in the top 90 cm of the profile. The results suggest that soil nitrate levels follow a seasonal trend, ranging from a high of 3.5 mg kg-1 to 5.7 mg kg-1 prior to turf growth to <2.0 mg kg-1 during periods of active growth. Compared to traditional agriculture, actively growing bermudagrass maintain relatively low levels of nitrate, thus minimizing potential environmental contamination."
