How to Use This Calculator
- Enter your soil texture class or measured clay and organic matter percentages.
- Input the CEC value from your soil test report in meq per 100g.
- Set your target cation ratios (Ca:Mg, Ca:K).
- Review the Cation Saturation percentages for calcium, magnesium, potassium, and hydrogen.
- Use the Lime or Gypsum Recommendation output to balance cation ratios for optimal crop uptake.
