Canopy
Reflectance with Multispectral Radiometry
Turfgrass quality is typically estimated by visual observations of uniformity, color, and density. Consequently, quality ratings are subjective and may vary among evaluators or even with the same evaluator over time. Conversely, multispectral radiometry measures shortwave solar reflectance from turf canopies in the visible and near-infrared ranges and may provide a more objective, quantitative method for estimating turfgrass quality. Canopy reflectances may also be a good indicator of environmental stresses in turfgrasses, such as drought stress.
