Connecticut's land-grant extension publishes a method — not a one-size-fits-all rate. UConn SNAL uses SMP or Sikora buffer. Live inputs: Mehlich buffer acidity and crop pH goal from Connecticut's published method. 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 Mehlich buffer acidity value on your lab report and your crop's published pH goal, exactly as Connecticut publishes them. UConn SNAL uses SMP or Sikora buffer. Enter those values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
Connecticut sizes lime from Mehlich buffer / exchangeable acidity per its own published tables. UConn SNAL uses SMP or Sikora buffer. Source: UConn Soil Nutrient Analysis Laboratory — SMP / Sikora buffer.
Zone Forge computes Connecticut lime from that state's published land-grant method (Mehlich buffer / exchangeable acidity as Connecticut's published lime method reads it, with the crop's published pH goal) — lime calculator, soil-test fertilizer, and full variable-rate prescriptions.
