For a solid, multiply the percentage by the weight of material you will add to the tank. The result equals the pounds of calcium per gallon pound of formulated product. Determine the rate of formulated material you intend to apply per acre per application. For a specific calcium product this is usually listed on the label. Multiply the amount of material per acre by the number of applications to be made during the season.
Result equals the amount of total product per acre per season.
The result equals the total amount of elemental calcium per acre per season. Compare the result from Step 5 with our recommendation of 4 to 14 pounds of elemental calcium per acre per season. Compare the season-long cost of materials. Multiply the amount of material used per season times the cost of the material. Compare the cost of elemental Ca.
