Tennessee's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. UT Soil/Plant/Pest Center uses an Adams-Evans family buffer; exact reagent not publicly stated. Enter your soil-test values in the free calculator and Zone Forge returns tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.

It depends on your soil's buffer/acidity reading and your target pH — Tennessee publishes a method, not a single number. UT Soil/Plant/Pest Center uses an Adams-Evans family buffer; exact reagent not publicly stated. Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
