Minnesota's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. Enter your soil-test values in the free calculator and Zone Forge returns tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.
Area 1 eastern + Area 2 western (Red River Valley) use same Sikora method but produce different rates.

It depends on your soil's buffer/acidity reading and your target pH — Minnesota publishes a method, not a single number. Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.

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