  • About

normalized difference vegetation index (NDVI) is the most widely used indicator of plant biomass in agriculture. In viticulture, NDVI provides a relative measure of the size and density of the canopy and therefore correlates with vigour. It is calculated from measures of reflected light at wavebands corresponding to red and infrared light. See also remote sensing and plant cell density.
