Abstract/Contents:Presents a study conducted to "develop an algorithm that would convert the RGB [red green blue] readings from the Spectrum TCM500 turf meter into the more useful CIE [Commission Internationale d'Eclairage] measurements of hue, chroma (satuaration [saturation]), and lightness." Details the materials and methods used in the study, stating that "flats were fertilized with varying rates of nitrogen to create a wider color response. At six different weekly intervals, turf was assessed for CIE color, TCM RGB, chlorophyll concentration, clipping yield, and visual color." Results indicated "significant multiple regressions relating CIE hue, lightness, and chroma to TCM RGB values, across sample dates and turf species." Concludes that "results of this study suggest that RGB measurements from an inexpensive reflectance meter can be used to describe turf color responses objectively."
