BECK’S OptRx ® Variable Rate Nitrogen<br />
OptRx crop sensors measure and record plant health data in real-time using reflectance<br />
of light shone on growing corn plants. Sensors can be installed across an application<br />
boom to collect information while sidedressing nitrogen. Data is logged and mapped to<br />
be used for analysis for real-time variable rate applications. OptRx sensors help<br />
growers apply nitrogen based on crop vigor. For example, the sensor tells the applicator<br />
to apply less nitrogen on healthy corn plants and more nitrogen on weaker, nitrogen<br />
deficient corn plants, according to a calibration specific to that field. In addition, OptRx’s<br />
advanced light-sensing technology is not dependent on ambient light, which offers<br />
maximum flexibility for use both day and night.<br />
The protocol for the 2014 OptRx trials consisted of growers reducing their normal<br />
nitrogen rate by 50 lb. N/A. and then implementing the OptRx system to apply variable<br />
rate nitrogen as a way to finish their overall nitrogen program.<br />
