Chapter 1 – Introduction
Nutrient supply within a field can be highly variable, as a crop
canopy absorbs nutrients at different rates at different locations. As a
result, uniform blanket application of nitrogen fertilizer can result in
over and under fertilization. With Topcon’s CropSpec sensor system,
you can measure the current local nitrogen supply and adapt the
fertilizer application rate to meet crop requirements accurately.
CropSpec sensors allow operators to determine the nitrogen nutrition
status of their crops, making it easier to estimate biomass and
nitrogen uptake. The sensors measure plant reflectance to determine
chlorophyll content, which is closely related to the nitrogen
concentration in the leaf. This non-destructive, non-contact method
provides accurate, stable readings and repeatable values which can
then be related to crop health.
The CropSpec feature is integrated as a real-time crop monitoring
application for use with the X Family consoles. CropSpec operates
with the Variable Rate Control (VRC) program or any of the
application controllers and allows the user to monitor in-field
variability, treat on-the-go and keep data for future analysis or
prescription application.
The CropSpec solution uses a two-sensor or single-sensor
configuration that mounts on the cabin roof.
Do not look directly into the sensors. Lasers may cause
permanent eye damage.
