The GreenSeeker handheld crop sensor is an affordable, easy to use measurement device that can be used to assess the health—or vigour—of a crop. Readings taken by the GreenSeeker handheld can be used to make non-subjective decisions regarding the amount of fertiliser to be applied to a crop, resulting in a more efficient use of fertiliser—a benefit to both a farmer’s bottom line and the environment.
Use the Connected Farm™ app on a smartphone or tablet to calculate fertiliser application rates from crop readings taken with the GreenSeeker handheld.
How Does it Work?
- Upon pulling the trigger, the sensor turns on, emits brief bursts of red and infrared light, and then measures the amount of each type of light that is reflected back at the sensor.
- The sensor continues to sample the scanned area as long as the trigger remains engaged.
- The strength of the detected light is a direct indicator of the vigor – or health – of the crop.
- The sensor displays the measured value in terms of an NDVI reading on its LCD display screen. NDVI readings can range from 0.00 to 0.99; the higher the reading, the healthier the plant.
To ensure the accuracy of your readings, hold the sensor 24″ – 48″ (60 – 120 cm) above the crop when the trigger is pulled.
The sensor’s field of view is an oval; the field of view widens as the height of the sensor above the ground increases
