Kansas's land-grant extension publishes a method — not a one-size-fits-all rate. K-State MF2586 (Jan 2024) — Sikora buffer with three target-pH equations. 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.
Three K-State target-pH regimes: 6.8 (SE Kansas + NE Kansas alfalfa/clover); 6.0 (NE Kansas other + central/western); 5.5 cash-flow exception.

It depends on the inputs Kansas's land-grant method publishes — not a single national number. K-State MF2586 (Jan 2024) — Sikora buffer with three target-pH equations. Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
