The Normalized Difference Vegetation Index (NDVI), which helps farmers visualize the health of their plants, is typically captured on a per-field basis via satellite or airplane flyby. Now, NDVI can be captured on a per-plant basis with the Trimble GreenSeeker handheld crop sensor.
The device instantly calculates NDVI by positioning the sensor over a plant and pulling the trigger. Trimble officials say they hope farmers and consultants will use the GreenSeeker as an affordable entryway into NDVI technology. Readings can be used to determine basic nutrient response, yield potential, herbicide efficacy, pest impact and more. In addition, the device can be used to track field conditions throughout the growing season.
"The GreenSeeker handheld removes the guesswork so farmers can more efficiently run their operations, making informed decisions about their crop based on compiled data to ultimately
increase profitability through input savings," says Erik Arvesen, vice president of Trimble’s agriculture division.
