  1. Repeatable Auto-Guidance for Strip Till Crop Production Than Hartsock John Deere Ag Management Solutions

  2. Agenda • Strip Till Defined • Benefits • Challenges • GPS Accuracy • RTK Auto-Guidance

  3. Strip Till Crop Production • Creation of berms of soil 2-4 inches tall, 6-10 inches wide • Subsurface placement of nutrients (optional) • Placement of the seed on top of the strip

  4. Perceived Strip Till Benefits • Reduced costs • Fuel/labor/machine usage • Replace Fall chisel plow pass with strip till bar • Eliminate Spring tillage pass • Fertilizer • Reduced fertilizer rate compared to broadcast

  5. Perceived Strip Till Benefits • Increased Yield • Dry, warm strip of soil  improved emergence • Seed proximity to fertilizer

  6. Perceived Strip Till Benefits • Less tasks at planting • Eliminate Spring tillage pass • Eliminate starter fertilizer on planter

  7. Strip Till Challenges • Time to complete strips in the Fall • Accuracy of the seed placement in relation to the strip • Visibility of strips during planting • Mismatched strip till bar / planter widths • Manual driving error • Implement error

  8. Dealing with the Challenges • Mechanical markers on the strip till bar • Plant one row of wheat during the strip till pass • Use integral (3 point) implements instead of pull type • Make strips/plant only during daylight • GPS auto-guidance

  9. GPS Auto-Guidance • Integration of GPS and the steering system of a tractor to automatically steer the tractor

  10. GPS Accuracy • Pass-to-pass • Error between two passes made within 15 minutes • Used to describe correction signals that do not offer repeatability • Static accuracy - repeatability

  11. GPS Correction Signals • Submeter • 1 foot pass-to-pass accuracy • WAAS, Omnistar VBS, StarFire SF1 • Decimeter • 4 inch pass-to-pass accuracy • Omnistar HP/XP, StarFire SF2 • Centimeter • Sub-inch repeatability • RTK

  12. GPS Auto-Guidance • Accuracy and price are related Strip Till 1 inch Accuracy 4 inch Row Crop Broadacre 1 foot $5,000 $15,000 $35,000 System Price

  13. RTK (Real Time Kinematic) GPS • Components • Base Station • GPS receiver • RTK radio • Stable mounting structure • 12 volt power source • Rover • GPS receiver • RTK radio

  14. Using RTK GPS in Strip Till • Setup base station in a repeatable location • Form strips • Save guidance track information (AB line) • Recall guidance track information in the Spring • Plant on strips

  15. RTK Auto-Guidance Advantages • More acres per day • Drive faster • Work later • Create straighter rows • Manual driving errors eliminated

  16. RTK Auto-Guidance Advantages • Reduce guess row variability  allow mismatched implements (strip 12, plant 16)

  17. RTK Auto-Guidance Advantages • Year-to-year repeatability • Residue management – offset from previous years crops • Use same fertilizer band over multiple years

  18. Summary • Strip till advantages are related to the seed proximity to the tillage strip • RTK auto-guidance can deliver advantages in a strip till production system
