The use of crop sensing technology is one of the fastest growing segments in precision farming.

Crop Spec

Crop Management, Accuracy and Control

Topcon CropSpec crop canopy sensors work with either the X30 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.

The benefits

  • Reduce fertilizer costs by applying based on crop need
  • Create prescription maps, or prescribe and apply in a single pass
  • Cab-mounted sensors protected and out of harm’s way
  • Largest sensor footprint in the industry for better results
  • On-the-go averaging with user-determined target rates
  • Views crops at a uniform diagonal to minimize error

How it works

  • CropSpec sensors measure biomass variability
  • For optimum crop performance, variable biomass requires variable input application rates
  • CropSpec measures and calculates input rates in real time – at the same recording and displaying both crop variability and applications in easy to read maps, in all conditions, 24/7.

Ideal for

  • Spraying & Spreading
  • Crop Sensing
  • Connectivity/Data Management
