How this estimate works

Lime is estimated from the soil-test buffer pH to your target pH and adjusted for the lime neutralizing index, following provincial soil-fertility guidance.

Planning estimate only. Local extension, soil lab, veterinary, apiary, and label guidance should override a calculator.
