  • What is the problem
  • What is the goal
  • Time and Money Investment
independence of variables
Independence of Variables
  • If you want to fix everything
  • Don’t chase after one thing.
  • Yield Monitor data for
    • Phosphorus Potassium Lime
  • Soils data for
    • Nitrogen and Sulfur
  • N and S (mobile) are yield based
  • P and K (immobile) are soil test based
  • Lime is Buffer Index based
determining the variable
Determining the Variable
  • Using 1 factor to determine other unrelated factors
