Soil pH is one of the most important properties in determining the cycling and availability of soil nutrients. Soil testing regularly and applying lime to maintain recommended pH levels should be the first step growers take to assure crops have sufficient availability of nutrients. Soil pH should generally range from 6.0 to 6.8 in mineral soils, but different field crops require different soil pH levels for optimum performance.
Indiana, Michigan, and Ohio each use different metrics to rate the neutralizing ability of lime. As a result, Ohio liming recommendations differ from Indiana and Michigan recommendations.
