Custom Zinc to PPM

• Product: Zinc Sulfate
• How to Run
  • Enter in your desired Zn PPM in the “Vars”
  • The formula will generate a prescription from your most recent soil test

Balance Zinc/Phos (Recommended)

• Product: Zinc Sulfate
• How it works:
  • No User Variables
  • Balances your Phos:Zn Ratio
    • 10:1 Phos:Zn if a Olsen P test is available
    • 7.5:1 Phos:Zn if a Bray or Mehlich 3 test is available

Balance Boron/Calcium (Recommended)

• Product: Boron 15%
• Use: Apply Boron to be in line with Calcium (1ppm B: 1000ppm Ca)

Target Boron PPM

• Product: Boron 15%
• Use: Enter in desired Boron PPM

Balance Iron to Mn - 50% Iron

• Product: Iron 50%
• What it does:
  1. Case 1: If Iron is low (<100) and still higher than Manganese → boost Fe to 100.
  2. Case 2: If Iron is low (<100) and Mn is higher → boost Fe to 100 and correct the Mn:Fe imbalance. 
     1. (Roughly 2ppm Fe:1ppm Mn)
  3. Case 3: If Iron is OK (≥100) but Mn is higher → add Fe to get 50% more than Mn.
  4. Default: If none of those conditions apply, return 0.

Balance Zinc/Copper

• Product: Copper Sulfate 25%
• Use: Apply copper to be in balance with your zinc ppm.
  • 2:1 Zinc: Copper

Mn Balance - M3 Test

• Product: Manganese Sulfate
• Use: 
  • Apply Manganese to get soil test levels to 45 PPM & Keep Mn at least half of Fe — to avoid antagonism from high Fe.
