Abstract

Agricultural limestone quality is measured by its neutralizing value and fineness of grind. Neutralizing value is determined by calcium carbonate equivalent (CCE). The higher the CCE, the greater the limestone’s ability to neutralize soil acidity. Reaction rate in the soil is affected by fineness of grind, with finer materials reacting faster with a soil to increase pH. Methods have been developed to calculate efficiency factors that involve using both CCE and material fineness. Regardless of the aglime material used, when the same amount of effective neutralizing material is applied and mixed thoroughly with the soil, the pH change in the zone of application will be the same.
