Trimble GreenSeeker Handheld Crop Sensor

The Trimble GreenSeeker handheld crop sensor is a simple farm management tool that can be used to assess the heath or vigour of a crop in order to make better nutrient management decisions on your farm. The GreenSeeker crop sensing system helps farmers to effectively and precisely manage crop inputs on the go by applying the right amount of fertilizer, in the right place, at the right time.

The GreenSeeker instantly take readings of crop’s health. Readings can be used to make non-subjective decisions regarding the amount of fertilizer to be applied to your crop, resulting in more efficient use of fertilizer—a benefit to the farmer and the environment.

How it works

• The sensor emits brief bursts of red and infrared light, and then measures the amount of each type of light that is reflected back from the plant.
• The sensor continues to sample the scanned area as long as the trigger remains engaged.
• The sensor displays the measured value in terms of an NDVI (Normalized Difference Vegetation Index) reading ranging from 0.00 to 0.99 on its LCD display screen.
• The strength of the detected light is a direct indicator of the health of the crop; the higher the reading, the healthier the plant.
