OptRx® Crop Sensors
OptRx Crop Sensors measure and record data about crops in real time using the reflectance of light shined on the growing plants.
Meeting your crop sensing needs.
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.
What makes OptRx crop sensors stand out from the competition?
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.
When we variable rate spread based on the reading from the OptRx, we are able to put the nitrogen where it needs to be. - Eric Godwin, Prime Meridian, MO
Organic material is one of the most significant sources of nitrogen in the soil. The more organic matter present, the more nitrogen the soil produces. Because organic matter concetrations differ across soil types, nitrogen availability in the soil can vary greatly throughout a field.
Denitrification occurs as a result of poor drainage and uneven moisture distribution across the field. In standing water, nitrogen in the soil changes into a gas and is lost to the air, leaving soil in some areas of the field nitrogen deficient. Denitrification can cause a loss of five percent of nitrogen per day, causing significant variation across the field.
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.
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.
