Kentucky's land-grant extension publishes a method — not a one-size-fits-all rate. UK AGR-1 (2025-2026) — Sikora-2 buffer with three target water-pH tables (6.4 / 6.6 / 6.8). 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 Kentucky's land-grant method publishes — not a single national number. UK AGR-1 (2025-2026) — Sikora-2 buffer with three target water-pH tables (6.4 / 6.6 / 6.8). Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
