2. What is Precision Agriculture? Define Precision Webster's Dictionary Definition: Quality of being precise, definite, exact, very accurate, distinguished from every other. Webster's Dictionary Definition: Quality of being precise, definite, exact, very accurate, distinguished from every other. 3. What should growers be able to accomplish with Precision Technology? Increase Yield and/or Reduce Input Costs Profit!! Must = 4. Are Precision Ag Solutions Attainable? Are Precision Ag Solutions Repeatable? Are Precision Ag Solutions Sustainable? Yes Do they promote good stewardship? 5. Does Variable Rate = Precision?? VRT VRI VRM!! 6. Traditional Approach for Zone Development Satellite Images (Multiple Year) Yield Maps (Multiple Year) Grid Samples (Point to Point Variation) USDA Maps (50+ year old technology) Whats the problem with these options for zone development?

Soil and Landscape are Fixed Variables They Form a Fixed Foundational Base 18. Where do we begin with EC/RTK DATA? Analyze the Yield Data Identify Yield Variability 19. Analyze the Yield Data 20. CropMetrics Precision Ag Approach to Soil Moisture Management for 21. How do we control irrigation to maximize root growth and increase profits? Routinely measure soil water status to account for: Rainfall Mechanical Irrigation applications Crop water use Apply water at the right time, right amount, in the right locations of the field based on: Soil water storage availability Active root zone of crop Water needs of the crop 22.
