How to Use This Calculator
- Enter your current soil organic matter percentage from a recent lab test.
- Set your target organic matter percentage.
- Input annual organic inputs in tons per acre (compost, manure, crop residue).
- Review the Estimated Carbon Sequestration Rate and Years to Target.
- Use the Organic Matter Influence on CEC output to understand its effect on nutrient-holding capacity.
