Kansas's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. K-State MF2586 (Jan 2024) — Sikora buffer with three target-pH equations. Enter your soil-test values in the free calculator and Zone Forge returns 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 your soil's buffer/acidity reading and your target pH — Kansas publishes a method, not a single 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.

Zone Forge computes every Kansas recommendation from that state's own published land-grant method — lime, soil-test fertilizer, and full variable-rate prescriptions. See the science →
