Green Seeker Ndvi Meter

The GreenSeeker Handheld Crop Sensor is a portable, precision optical instrument designed for rapid in‑field measurement of crop health via the Normalized Difference Vegetation Index (NDVI). Developed by Trimble, this device allows agronomists, farm managers and precision‑agriculture consultants to assess plant vigor and biomass, make informed nutrient management decisions (such as nitrogen application) and monitor crop stress, canopy growth and potential yield.

By emitting short bursts of red (660 nm) and near‑infrared (780 nm) light and measuring their reflection from plant leaves, the GreenSeeker computes an NDVI value (0.00‑0.99) which correlates to crop health: higher NDVI indicates healthier, more vigorous vegetation.
While hand‑held, the sensor integrates easily into field workflows—simply point it 60–120 cm (24–48″) above the canopy, press the trigger, and get a reading. Multiple readings across a field allow mapping of crop variability and help determine site‑specific fertilizer rates, thereby helping increase yield and reduce input costs.
