  • Analysis of fertilizer applied (e.g., 11-52-0)
  • Application method (soil injected, incorporated, surface-applied, etc.)

  • Temperature, precipitation, and other weather conditions at the time of application
    • For surface applications only: was the ground frozen or snow-covered (yes/no)?
