Benefits and performance

Trimble’s suite of input management solutions make planting, seeding, spraying and spreading activities more accurate and efficient. Here are a few of the benefits the GreenSeeker handheld crop sensor brings to farmers around the world.

More efficient fertilizer applications

By having more specific crop health information, you can make nutrient applications more efficient, benefiting your bottom line and the environment.

More accurate scouting efforts

Gather crop health readings in real-time to take your scouting insights to the next level.

How does GreenSeeker work?

To help you make well-informed nitrogen decisions based on sensor readings, a team led by researchers at Oklahoma State University developed a Sensor-Based Nitrogen Rate Calculator for a variety of crops and geographies.

• 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 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
