New York's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. Cornell CNAL / Agro-One uses Modified Mehlich Buffer as the primary lab method. Combined source v2.0: lime (Modified Mehlich Buffer, unchanged from v1.0) + Pdoc 2022/Kdoc 2024/Ndoc 2023 Cornell Morgan nutrient block. Enter your soil-test values in the free calculator and Zone Forge returns tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.
Published source: New York — Cornell NMSP / CNAL — Agro-One (combined lime + nutrient)
It depends on your soil's buffer/acidity reading and your target pH — New York publishes a method, not a single number. Cornell CNAL / Agro-One uses Modified Mehlich Buffer as the primary lab method. Combined source v2.0: lime (Modified Mehlich Buffer, unchanged from v1.0) + Pdoc 2022/Kdoc 2024/Ndoc 2023 Cornell Morgan nutrient block. Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.
