Delaware's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. Delaware Coastal Plain — UDel uses classical Adams-Evans with p-nitrophenol reagent. 67% ECCC published basis. Enter your soil-test values in the free calculator and Zone Forge returns tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.
