The use of crop sensing technology in grains, cereals and other production ag crops is one technique to increase plant health and yield potential. OptRx ® Crop Sensors measure the needs of your crop and provide  application rate recommendations for agrochemicals in real time to maximize  your profit.

The OptRx® Difference

What makes OptRx® crop sensors stand out from the competition?

• 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 flagship Ag Leader 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.
  

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 installed across the application boom 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. This kind of data is the key to precision farming. Collect information in the fields, analyze and then make decisions based on the data.
  
• The OptRx® crop sensor helps growers apply agrochemicals  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 advanced light-sensing technology is  not dependent on ambient light – offering maximum flexibility to be used day or  night.
