Comparing SuperCal 98G and AgLime

To determine what liming material is best for you and most economical, you need to know:

Percent purity (CCE), and

Grind fineness (ECCE) of the material.

Each state has a testing procedure to determine fineness. To ensure you getting the best product for your situation, have your dealer tell you about the fineness and purity of the liming products he has available.

Limestone is made up primarily of calcium carbonate (CaCO3).

CaCO3 (Limestone) is not very soluble in water so it must be finely ground to effectively neutralize soil acid.

SuperCal 98G is finely ground 98% pure calcium carbonate	AgLime coarsely ground 50% ECCE

Finely ground particles raise the pH faster than course particle sizes. 

Please note that 4 and 8 particle sizes are not considered.

If you do come across a fine Ag-Lime most of the fine material will be lost when spreading, resulting in an uneven spread pattern. 

Pelletizing is the best way to put fine particles on the ground.
