Oxy-Cal™
Calcium supplement
Oxy Cal™ is 60% calcium peroxide and can disassociate in soil to break down into available calcium. The process occurs slowly and the free calcium will help buffer acidic media. Because this product is an irritant, be sure to wear appropriate safety equipment when handling.
