OptRx sensors are a powerful tool in a range of crops including broadacre, horticulture, viticulture and grazing.
The OptRx Difference
What makes OptRx crop sensors stand out from the competition?
- 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.
- 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.
How OptRx Works
OptRx Crop Sensors measure and record data about crop health in real time using the reflectance of light shined on the growing plants. Sensors can be installed across a boom or other configurations to collect information while driving through the field while also carrying our other operations. The data is logged and mapped to be used in further analysis – or for real-time variable rate applications.
In addition, OptRx’s advanced light-sensing technology is not dependent on ambient light – offering maximum flexibility to be used day or night.
What OptRx Can Do For You
- educe application of nitrogen in nitrogen-rich areas.
- Increase yield potential in nitrogen-poor areas of the field.
- Record crop vigor variation data across the field.
- Balance the effects of organic material variability across the field.
- Improve yield potential for crops harmed by denitrification due to poor drainage.
Other Helpful Cutting Edge Tools
Vegetation Index (VI)
Using built-in intelligence, OptRx assigns a “crop vigor” number or Vegetation Index (VI) value based on plant biomass and nitrogen content. The VI evaluates the quality and variation across the field.
Calculating Nitrogen Rate
To determine nitrogen rate, OptRx must first identify the VI value that represents a plant with sufficient nitrogen available; this is called the VI Reference Value. To determine a VI Reference Value, users must drive the applicator over the healthiest looking plants for a minimum of five minutes. This process calibrates OptRx crop sensors for the given growth stage.
OptRx crop sensors are ideal for applying fertilizers, pesticides, defoliants, growth regulators and other agrochemicals on-the-go at the rates necessary for optimum performance. Working with an agronomist or crop consultant, select a Vegetation Index range and assign the recommended rates based on the range chosen.
