  1. Utilization of GPS Based Technology in Row Crop Research and Bulk Production at the Davis Purdue Ag Center 6230 N State Road 1 Farmland, IN 47340 765-468-7022 www.agriculture.purdue.edu/pac/davis/index.html

  2. One of 8 Ag Centers in Indiana • 623 acres – 450 Tillable • Corn, Soybeans, Wheat • Emphasis on Site Specific Ag • Long Term Timber Management • and Genetic Research

  3. Davis Purdue Ag Center (DPAC) 1917 2011 • Gift from Martha Davis in 1917 • Given in memory of her son Herbert Davis • Original gift was 385 acres • DPAC Expanded to Current Size in 1960s • Horses, Beef Cattle, Dairy Cattle • Hog Operation Phased Out in late-1990s • Row Crops

  4. Traditional Small Plot Research No Plot Equipment 2 ½ hours from Purdue Campus Heavy Clay, Poorly Drained, Variable Soils Most Fields – 30 acres in size Not Suitable for Small Plots

  10. Field History & Data Sets • Field Boundary • Soil Types • Tile Drainage • Yield Data • Soil Fertility Data • Cropping History • Fertilizer/Lime Applications • Topo Data • Soil EC Data • Aerial Images • Others DPAC Staff Verify Plot Plan Field Boundary Soil Types Project Utilizes Background Data in Developing Plot Plan Other Data Sets Tile Drainage Plot Plan

  11. Equipment Sized Systematically • Field Cultivator – 22.5 ft • Sunflower Disk – 18 ft • Disc Chisel – 9 shank • Planter 15 ft • Drill 15 ft • 28 UAN applicator 15 ft • Fertilizer Spreader 45 ft • Lime Spreader 30 ft • Sprayer 75 ft boom (15 ft sections) • Case/IH Combine – 15 ft grain table, 6 row corn head

  12. Commercial Computer Software Packages • Ag Leader SMS Advanced - Yield Data Processing, Prescription Files, Plot Size/Configuration, Grid Soil Sampling • Farmworks Software - Crop Records, Yield Data, Prescription Files, Grid Soil Sampling, SURFACE WATER MANAGEMENT • ESRI Inc - ArcView GIS

  13. GPS Equipment • Ag Leader - GPS 4100 • Trimble Navigation - AgGPS132 • Raven GPS Receiver WAAS • Farmworks - Navman Receiver • OmniStar USA Inc - Differential Correction Signal • Trimble RTK System

  14. GPS Based Technology System Rawson Drive PF3000 Pro Trimble FmX

  16. GPS Based Field Scale Research Projects Summary • Collaborative Studies with Industry and Other Agencies • Syngenta, Monsanto, Dow AgroSciences, Raven, Trimble, Natural Resources Conservation Service, PPI, USB • Soybean Plant Performance Study • Corn Fungicide Study • Corn FACT Plots ` • Herbicide Volatility Study • Performance of Harness and Degree Applied Mid-Post to Corn • Roundup Ready Corn Herbicide Versus Competitive Herbicide Products • Slow Release N Impact on Corn

  17. GPS Based Field Scale Research Project Information Information and Data From GPS Based Projects has been presented at Fields Days and Workshops Hosted at DPAC Annual Field Day Pioneer Diagnostic Training Day Info Ag Tour National Soil Classifiers Tour DuPont Crop Tour Valent Crop Tour Monsanto Crop Tour Programs Presented by Local Extension Educators Purdue Collaborative On-Farm Research Indiana crop producers have incorporated the use of GPS Based Technology into their operations. Experience at the Davis Purdue Ag Center and other PACs has helped researchers in developing a Purdue Collaborative On-Farm Research Program where Indiana crop producers, Indiana Certified Crop Advisers, county Purdue Extension Educators, and campus Purdue Extension field crops specialists work together to come up with answers to farming’s challenging questions.

  18. DPAC Staff • Superintendent – A/P • Service/Clerical • Research Faculty and Students Travel from Campus Empowering Staff • Ability of Staff • Expectations of Staff • Value of New Technology • Implementing Technology into Routine Operations • Patience • Repeated Use • Good Communication • EVERY QUESTION/CONCERN IS A GOOD QUESTION!!

  19. GPS Based Technology • Allowed Us to Bring Together Field Scale Research • and Bulk Production Practices In An Efficient and • Effective Manner • Advantages • Production Equipment – Research Purposes • Ag Center Staff Can Implement Plots • Research Conducted Under “Field Conditions” • Variable Rate Fertilizer/Lime Applications • Data Quality/Consistency – Extraction of Data • Multiple Data Sets – Know the Fields • New Data Sets – Verify Old Data Sets • More Accurate Input Orders • More Accurate Applications • Disadvantages • Volume of data generated • Dependence on electronic equipment • Variability of plots

  21. Purdue Agricultural Centers – Financial Overview Regional Agricultural Center funding comes largely from three sources: State line-item (33%) Sales of commodities (55%) Endowments & minor grants (12%) • Funding GPS Based Technology • Commodity Sales • Endowment Funds • Faculty • Industry • Other Agencies

  22. What Does the Future Hold??? • Use of GPS Based Technology has Expanded to other Ag Centers and ACRE • On Farm Research • RTK Systems have the potential to change how we look at row crop research and production
