GreenSeeker® Variable Rate Application System addresses nitrogen use efficiency
The GreenSeeker® Variable Rate Application System developed by NTech Industries, Inc., in cooperation with Oklahoma State University, is a sensor-based variable-rate fertilizer application system that can increase nitrogen use efficiencies in field crops by addressing spatial and temporal variability. The GreenSeeker® sensors detect crop potential yield and total nitrogen in the plants and uses that information to adjust top-dress nitrogen application rates "on the go" with real time sensor data. The GreenSeeker® system is not dependent upon a GPS signal for application location, but can use GPS to develop an "as applied" map. The equipment is designed to be integrated onto new, and retrofit, self-propelled and pull-type applicators. The system features simple operation allowing an operator to insert set-up information through a compact-flash card. Once in the field, the system can be engaged and the system operated conventionally. The GreenSeeker® Variable Rate Fertilizer System will include an in-cab printer that can be used to print field summaries for customers.
