Calcium where you want it, when you want it.

Calcium is a critical element in the formation of plant cell walls. That is why adequate levels of available calcium help provide a strong turf that can stand up to heavy play and mechanical damage. Unfortunately, plant tissue can easily become calcium deficient, even in soils with adequate calcium levels. 

Quelant-Ca is formulated with a balanced proportion of calcium and free amino acids to aid in the prompt absorption within the plant. With Quelant-Ca in your fertility program, you can quickly correct and maintain the calcium levels in your turf, even during times of plant stress.
