118 Forage mass estimation of sudangrass-based pasture using vegetation indices.
Journal of Animal ScienceAbstract Remote sensing (e.g., satellites), can detect the electromagnetic radiation reflected by plants and translate it into numerical values. The values from different spectral bands can be combined mathematically into vegetation indices (VI) that have been used to assess plant health, activity, and biomass.
