Manage Nitrogen Application and Maximize Yield Potential with OptRx Crop Sensors

Melissa SandfortAg Leader, Insights Weekly

Insights Weekly Are you willing to take whatever steps needed to ensure maximum yield potential? Variable rate nitrogen application utilizing OptRx crop sensors is one way to reduce the risk of over fertilizing in early growth stages and ensure optimum plant health across the entire field.

How OptRx Works
OptRx crop sensors are installed across the application boom and integrate seamlessly with DirectCommand™ on your INTEGRA™ display.

Emitting its own light source, the sensors measure crop health based on plant mass and light reflectivity readings. By identifying the plant health of the crops, OptRx determines the amount of nitrogen plants with lower crop health need.

Chad Fick, Ag Leader crop sensor product specialist, gives us a bigger picture overview of OptRx and how it works. [wpaudio url=”″ text=”Listen to Fick explain”]

By using OptRx, you can maintain a uniform, consistent nitrogen-rich soil base across the field through the key parts of the growing season. Fick explains why precise nitrogen application is so critical to plant health and increased yields. [wpaudio url=”″ text=”Listen to Fick explain”]

Crop Sensor Rate Table
Nitrogen is not the only agrochemical that can be applied on-the-go with OptRx crop sensors. Thanks to the new Crop Sensor Rate Table, many agrochemicals, such as fertilizers, pesticides, defoliants, growth regulators and others, can now be more effectively applied at varying rates according to crop health.

The new Crop Sensor Rate Table allows you to choose a Vegetative Index range and assign the recommended rates based on those ranges. To take advantage of the new rate table, simply update your INTEGRA firmware to version 3.3.

OptRx Data: Independent Test
