How OptRx Works

OptRx crop sensors measure and record data about crops in real-time using the reflectance of light shined on the growing plants. Sensors can be mounted on virtually any type of vehicle to collect information while driving through the field. The data is logged and mapped to be used in further analysis – or for real-time variable rate applications – in both corn and wheat production.

The OptRx crop sensor helps growers apply nitrogen based on crop vigor. For example, the sensor tells the applicator to apply less nitrogen on healthy corn plants and more nitrogen on weaker, unhealthy corn plants, according to a calibration specific to that field.

In addition, OptRx’s patent-pending advanced light-sensing technology is not dependent on ambient light – offering maximum flexibility to be used day or night.

Description

The OptRx Difference

What makes OptRx crop sensors stand out from the competition?

OptRx crop sensors

  • Virtual reference strip. Unlike many other crop sensors on the market, the OptRx Crop Sensor doesn’t require a nitrogen-rich strip for making nitrogen application recommendations. Instead, OptRx relies on a new technology called a virtual reference strip. Growers simply identify the healthiest area of the field and scan that area in real time, rather than applying excess nitrogen to an area of the field pre-season and mapping that point.
  • User-friendliness. The OptRx sensor offers a user interface that exceeds previous sensors. OptRx directly interfaces with the InCommand™ 1200 display to show the sensor readings and mapping onscreen along with other application data, such as rate control and automatic swath control.
  • Red-edge light wave. OptRx uses a red-edge light wave to scan plants. Most competitive products use only a red wavelength, which has been shown in studies to be non-responsive at high plant density. The red-edge lightwave stays responsive to health-stress on plants at later growth stages than other competitive products.
  • Single algorithm. OptRx crop sensors use a single algorithm application. Trials have been conducted in multiple states that have shown positive results of using a single algorithm in comparison to multiple algorithms.
