West Virginia's land-grant extension publishes a method — not a one-size-fits-all rate. WVU LR Mehlich Buffer — combined source v2.0 (2026-05-27). Lime block now ships verbatim WVU Extension Crop Fertilization Recommendations Table 14 regression LR = 100.1 - 26.56·BpH + 1.728·BpH² (replaces prior placeholder PSU acidity table) + Table 14 verbatim lookup (BpH 4.2-6.6); surface-applied rules (2 ton ENV trigger at pH<6.0 or <6.5 depending on crop optimal pH); alfalfa 3-ton no-till and 3+3-ton conventional seeding rules; Table 9 crop pH preferences (37 crops). Lime quality reference: ≥90% CCE, 20/100 mesh distribution. 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.

It depends on the inputs West Virginia's land-grant method publishes — not a single national number. WVU LR Mehlich Buffer — combined source v2.0 (2026-05-27).
