Do Active Canopy Sensors Measure Biomass or Chlorophyll in Corn?Agronomy Conference Proceedings and Presentations
Publication VersionPublished Version
AbstractVegetative indices from canopy sensors are currently being used as a tool to measure N deficiency in corn (Zea Mays L.). Symptoms of N deficiency include stunted growth (reduced biomass) and yellowing (reduced chlorophyll). It is unclear which sensor index is most useful. The objective was to determine if canopy sensor indices (NDVI and CHL) measure plant biomass or plant chlorophyll.
