  1. GreenSeekerTM Variable Rate ApplicatorEquipment and Applications

  2. GreenSeekerTMVariable Applicator: Equipment and Applications • How the GreenSeekerTM works • NDVI • GreenSeekerTM RT200 & RT500 • Corn and other applications

  3. Variable Rate Nozzle System Decision Making And Agronomic Strategy Computer and Sensor Assembly Direction of Travel Plant Sensor-BasedNitrogen Management

  4. Detection of Reflected NIR and RED +Sun Direction NIR and RED Modulated Illumination Target GreenSeekerTM Sensor Light Detection and Filtering

  5. Valve settings Light signal Calculate NDVI ? Lookup valve setting ? Apply valve setting ? Light Light Send data to UI ? detection generation Valves “Sensor” and Nozzles Sensor Function

  6. GREENSEEKERTM Applicator • Sense and treat each 2 ft by 2 ft area • Apply one of seven fertilizer rates based on the crops yield potential • Accomplish this while driving 15 mph • Operate day or night • Provide the capability to detect and treat other plant problems • Record and georeference sensor data for GIS analysis • Sense and spot spray weeds (current Patchen technology)

  7. 8 Stepped rates OFF to 7x Treats 24”x 24” area applying the target rate on 85% of that area Tri-valve Set for Varying Rate 1x 2x 4x
