| Abstract/Contents: | "Site-specific application of nutrients to turfgrass has the potential to save money and reduce environmental impact. The objective of this study were to develop a method to determine N content of and evaluate this application for two different turf species under different mowing heights. Nitrogen was applied at rates of 1.2, 2.4, 3.6, and 4.8 g N/m-2 periodically over a two-month period to annual bluegrass (Poa annua L.) and creeping bentgrass (Agrostis palustris Huds.) mowed at heights of 14 mm or 4 mm. A direct light spectrometer was used to measure reflectance expresed as "log1/R". After spectrometer readings were obtained, clippings were harvested from each plot and analyzed for N using a dry combustion CNS analyzer. Analysis of the data yielded correlation between reflectance values and plant tissue N content." |
