pHusion Calcitic Limestone is a calcitic pelletized limestone that is reacted with an organic acid. This unique organic acid is a combination of Calcium Lignosulfonate and Lignosulfonic Acid. University tests show that 500 lbs. of limestone treated with organic acid gives equal or better results than one ton of traditional pelletized limestone per acre. pHusion Calcitic Limestone increases the soil pH as much as 4 times faster than conventional limestone products at similar application rates.

When pHusion Calcitic Limestone is dissolved by water, the organic acid accelerates the reaction of releasing available Calcium and neutralizes the hydrogen (H+) ions in the soil. The Calcium Lignosulfonate and Lignosulfonic Acid convert the calcium in pHusion Calcitic Limestone into a more soluble form, readily available for plant uptake or pH adjustment. pHusion Calcitic Limestone addresses both the calcium needs of the plant, as well as the growing media pH. pHusion Calcitic Limestone will help achieve a uniform calcium profile throughout the soil. 

Directions for Use:
Tees, Fairways , Sports Turf and Lawns: To maintain soil pH, apply 5 lbs. per 1,000 sq. ft. or 220 lbs. per Acre of pHusion Calcitic Limestone at least twice per growing season. Follow soil test(s) recommendations.

To adjust soil pH, apply 12 lbs. per 1,000 sq. ft. or 500 lbs. per Acre of pHusion Calcitic Limestone. This has the potential to raise the pH up to one full point (5.0 – 6.0) for soils that have a CEC of 10 or less, and to a soil depth of 4 inches. Retest and reapply, if needed, at this rate.

pHusion Calcitic Limestone is ideal for turf and horticultural application. Always use complete soil test(s) from a reputable laboratory to determine liming needs.
