Mississippi's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. MSU Soil Testing Lab uses a buffer method (specific reagent unverified). 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 — Mississippi publishes a method, not a single number. MSU Soil Testing Lab uses a buffer method (specific reagent unverified). Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
