What is Precision Agriculture?

Precision agriculture is the practice of managing specific field areas based on variability within the field. It involves using integrated technologies like GPS, GIS, yield monitors, variable rate technology, and remote sensing to optimize crop production inputs and make data-driven management decisions. This approach reduces waste, increases profits, and maintains environmental quality.

  1. What is Precision Agriculture? Precision Agriculture - Lesson 1

  2. What is Precision Agriculture?? • The practice of managing specific field areas based on variability within the field. (SSToolbox) • Managing each crop production input - fertilizer, limestone, herbicide, insecticide, seed, etc. - On a site-specific basis to reduce waste, increase profits, and maintain the quality of the environment. (John Deere) Precision Agriculture - Lesson 1

  3. What is Precision Agriculture?? • An integrated agricultural management system incorporating several technologies. The technological tools often include the global positioning system, geographical information system, yield monitor, variable rate technology, and remote sensing.(http://www.amesremote.com/section4.htm) Precision Agriculture - Lesson 1

  4. Traditional Mgt. Precision Mgt. 1/10-1/100 Acre 40-160+ Acres It’s About Management “Farming by the Square Foot” Precision Agriculture - Lesson 1

  5. Building Blocks of Precision Agriculture “A smorgasbord of technologies.” Yield Monitors Direct & Remote Sensing Precision Navigation Variable Rate Technology Global Positioning Systems Geographic Information Systems Precision Agriculture - Lesson 1

  6. Precision Agriculture Data Collection Analysis Farming Management Decisions

  7. Data Collection • Boundary Mapping • Remote Sensing • Weather Data • Soil Sampling • Crop Condition • Yield Monitoring • Irrigation Testing • Pest Scouting • Soil Moisture Precision Agriculture - Lesson 1

  8. Analysis • Determining Variability • Determining Possible Causes of Variability • How much do measured soil and crop characteristics vary? • How much do the variations affect crop yield and/or crop quality? Precision Agriculture - Lesson 1

  9. Management Decisions • Is it possible to change/mitigate the variability? • Will the change increase yield, increase quality, decrease inputs? • Is the change profitable? • How are you going to implement this change? Precision Agriculture - Lesson 1

  10. Farming • Applying the Decisions • Variable Rate Irrigation • Variable Rate Pesticide Application • Variable Rate Fertilizer Application • Variable Rate Seeding/Planting Crop Science 6

  11. Precision Agriculture Data Collection Analysis Farming Management Decisions

  12. Precision Agriculture • Now that we know the cycle of precision agriculture; What are it’s building blocks? • Global Positioning System (GPS) • Geographic Information Systems (GIS) • Applications: Yield Monitors, Direct and Remote Sensing, Precision Navigation, Variable Rate Technology Precision Agriculture - Lesson 1

  13. Global Positioning System (GPS) • Military Satellites • GPS Receivers • Locating your position on Earth • Prices range from $100 to $40,000 Precision Agriculture - Lesson 1

  14. Geographic Information Systems (GIS) • Tying information to it’s location on the Earth • Management Zones • Fertilizer/Pesticide Prescriptions • Maps and Data • “Layers” • History • Analysis by Location Precision Agriculture - Lesson 1

  15. Applications • Yield Monitors • Direct Sensing • Veris • EM38 • Remote Sensing • Aerial Imaging • Satellite Imaging • Precision Navigation • Variable Rate Technology Precision Agriculture - Lesson 1
