Missouri's land-grant extension publishes a method — not a one-size-fits-all rate. MU uses Woodruff buffer → Neutralizable Acidity → ENM lb/A. Missouri is the only state still on Woodruff. Live calculator uses this state's published method and citation. Enter the required soil-test values in the free calculator for tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.
Soil regions 5/6/7/8 (Cherokee Prairies, Ozarks, Ozark Borders) target pHs 6.6-7.0 for alfalfa due to high subsoil acidity; all other crops/regions use 5.6-6.0 or 6.1-6.5 ranges. Missouri's ENM method is not live in the calculator yet; the cited regional pH guidance applies.

It depends on the inputs Missouri's land-grant method publishes — not a single national number. MU uses Woodruff buffer → Neutralizable Acidity → ENM lb/A. Missouri is the only state still on Woodruff. Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
