The use of crop sensing technology in cereal and grain crops is one of the fastest growing segments in precision farming. Topcon CropSpec crop canopy sensors work with either the XD, XD+, X35 or X25 consoles to monitor in-field variability. CropSpec units mount on the cabin roof out of harm’s way, providing the largest sensor footprint in the industry, attaining more accuracy in application. CropSpec sensors measure plant reflectance to determine chlorophyll content, which correlates to nitrogen concentration in the leaf. This non-destructive, non-contact measurement method provides accurate, stable readings with repeatable values.
