How to Use This Calculator

Enter values for each soil health indicator: organic matter %, active carbon, aggregate stability, infiltration rate, and earthworm count.
Select your soil texture class to apply texture-adjusted scoring.
Review the score for each indicator on a 0-100 scale.
Check the Overall Soil Health Score and the letter grade assigned.
Focus management improvements on indicators scored below 60 for the greatest agronomic return.
