  1. Precision Agriculture: Past and Present Justin Ludwig

  2. Background • Biosystems and Agricultural Engineering (BAE) Junior • Decided on BAE • Okarche, OK • Grew up on 1,300 acre wheat, cattle, and hay farm • Up to 450 stocker steers in winter • Alfalfa and Bermuda grass hay • Been on the farm ever since age 3, cheap than a babysitter

  3. Precision Agriculture in the 90’s • 3 technologies became widely availabile • Global Positioning System (GPS) • Geographic Information System (GIS) • Remote Sensing

  4. GPS • Allowed farmers’ to find location in fields • Civilian got access in the 90’s • Started to produce yield maps in the late 90’s • Led to the light bar: http://www.trimble.com/agriculture/graphics/products/lb25.gif • Yield monitors • One of the first systems: • http://www.delmarlearning.com/companions/content/140188105X/trends/trends.asp

  5. GPS Today • Accuracy for John Deere Starfire Receivers • WAAS Static Accuracy: 30 inches • WAAS Pass to Pass Accuracy: 18 inches • Starfire 1, exclusive to John Deere, Static Accuracy: 30 inches • Starfire 1 Pass to Pass Accuracy: 13 inches • Starfire 2 Static Accuracy: 10 inches • Starfire 2 Pass to Pass Accuracy: 4 inches • Starfire 2 is used for precise guidance applications

  6. GPS Today • CNH Accuracy levels • AFS AccuGuideAutoguidance, AgGPSAutoPilot, AgGPSTrueTracker: 3 ft to sub in. depends on receiver • AgGPS EZ-Steer 500 Assisted Steering : 8 in. • AgGPS EZ-Guide 500: 3 ft to sub in, dependson receiver • AgGPS EZ-Guide Plus: 1 ft

  7. GPS Today • AGCO Accuracy: • Submeter WAAS Static: 39 inches, Dynamic: 10 inches • SubmeterOmniSTAR VBS Static: 31 inches, Dynamic: 8 inches • Decimeter OmniSTAR HP Static: 4 inches, Dynamic: 2 inches • Decimeter Local Base DGPS Static: 4 inches, Dynamic: 2 inches • Centimeter Local Base RTK Static and Dynamic: .8 inches

  8. Yield Monitors Today • Variety of monitors from John Deere, CNH, AGCO, Ag Leader, Trimble, and many others • Example of a Trimble Monitor: http://www.trimble.com/agriculture/yield-monitoring-and-mapping-capabilities.aspx?dtID=overview& • Ag Leader: http://www.agleader.com/products/yield-monitor/

  9. GIS in the 90’s • Created in 1960’s, became popular in the 90’s • 4 phases in GIS history • 1st phase- Decided what was important. 1960-1975 • 2nd phase- Experimental use by national agencies. 1973-1980 • 3rd phase- Commerical use. 1982-Late 80’s • 4th phase- User phase 90’s-Present • Early 90’s- GIS released • Late 90’s- Adoption by cities and community organizations

  10. GIS Today • Basis for Google and Bing Maps • Able to use rasters and vectors • Rasters-any digital image • Vectors- shapefiles made up of points, lines, and polygons

  11. GIS Today Agricultural Use • Used to share data, increase data, increase yields, predict outcomes, improve business practices • Save expenses • Submit government program applications • Insurance crops, proving yields

  12. Remote Sensing in the 90’s • Satellite imagery • Measure using the electromagnetic spectrum • Visible/Infrared Region • Infrared Region • Foundation of many sensors in use today • First models of many applications that have been improved • Grain bins sensor, Greenseeker, countless others

  13. Remote Sensing Today • Used to apply variable rate fertilizers/pesticides • New and improved versions of older sensing applications • Soil sampling

  14. Conclusions • Precision Agriculture has improved over the last 20 years, will continue to improve, cheapen • All help farmers • Reduce fatiage • Save money • Bring in new management practices
