v1.0 (2026-05-23) · University of Nebraska-Lincoln. UNL does not run a state lab; commercial labs use UNL recommendations under contract. Buffer pH method (historically Woodruff for sandy soils, SMP for high-Al; modern labs migrating to Sikora as an SMP substitute). Rate: 1,000-1,200 lb ag-lime/A per 0.1 buffer-pH unit below 7.0. Published rates assume **60% ECCE** limestone — unique baseline among the states. Eastern NE has measurable acidification; western NE often calcareous and lime rarely needed.
This source publishes a state method — its crop-specific rate tables are maintained in the extension bulletin rather than a fixed crop list, so Zone Forge doesn't claim a crop set here.
