Limestone quality booklet released
Proper use of limestone is one of the most important management strategies in crop production. Limestone should be the first soil amendment considered in cropping systems.

Limestone quality is defined by two factors-the effective neutralizing value and the degree of fineness. The neutralizing ability of the material is indicated by the calcium carbonate equivalent (CCE). The higher the CCE value, the greater the limestone's ability to neutralize soil acidity. Pure calcium carbonate (CCE of 100) is the standard against which all liming materials are measured. The CCE level is inherent in the limestone material, and it can not be changed.

The second factor is particle size or fineness of grind. The rate of reaction depends on the surface area of the liming material in contact with the soil. The finer the limestone is ground, the faster it will neutralize soil acidity. Limestone too coarsely ground will be very slow in raising the soil pH. Lime particle size is based on the percentage of materials that pass through 8-, 30-, and 60-mesh screens.

Those applying limestone are encouraged to obtain the publication "Illinois Voluntary Limestone Program Producer Information". The booklet, produced annually by the Illinois Department of Agriculture and Illinois Department of Transportation, indexes limestone samples from quarries that wish to participate in the Illinois Voluntary Limestone Program. Analyses of CCE, fineness scores, magnesium percent, and correction factors are included.

We have the latest booklet available for download.
