GreenSeeker_sensor_HRThe GreenSeeker crop sensing system is a variable rate application and crop vigor mapping system that offers a more efficient and precise way to manage crop inputs such as nitrogen. The system verifies, in real-time, the amount of nitrogen the soil has available using complex agronomic calculations called NDVI. The GreenSeeker system then determines a fertilizer prescription for instant application so that you are applying the right amount of nutrients needed by the plant at the right time.
