Illinois Voluntary Limestone Program Producer Information

Limestone should be the first soil amendment applied to the soil in crop production.  The rate of limestone application should be based on a soil pH test and recommendations in the Illinois Agronomy Handbook. When deciding which limestone to apply producers are encouraged to consult the "Illinois Voluntary Limestone Program Producer Information" booklet.  It is produced by the Illinois Department of Agriculture and Department of Transportation.  It indexes limestone samples from quarries that wish to participate in the Illinois Voluntary Limestone Program.  Analyses of Calcium Carbonate Equivalent (CCE) and fineness scores, plus correction factors are included in the booklet.
