Thank you for using the Art Wilson Co. Cal-CM Sulfate Calculator. This is a simple and easy-to-use tool that will allow anyone to compare the calcium values and cost of usage between Art Wilson Co.’s Cal-CM (with its100% gypsum guarantee), and any other source of calcium sulfate. The Cal-CM Sulfate Calculator works equally well for comparing agricultural grade, prilled, or solution grade material. Once you input your specific information into the yellow shaded areas, a cost comparison and tonnage requirement will calculate automatically. You will be able to print this complete analysis for future reference.

One helpful hint: If you do not know or have readily available the “lbs. of calcium required per acre”, simply use the following formula for the calculation:

Example 1: If you usually use Gypsum A at a rate of 1 ton (2000 lbs.) per acre, and the calcium percentage of the gypsum is 17%, your calcium requirement per acre would be 2000 x .17= 340 lbs.

Example 2: If you usually use Gypsum B at a rate of 2.5 tons (5000 lbs.) per acre, and the calcium percentage of the gypsum is 14%, your calcium requirement per acre would be 5000 x .14= 700 lbs.

Thank you for considering the Art Wilson Company.
