Jonathan Green Mag-I-Cal Organic Calcium 1000 sq ft 3.6 lb

Mag-I-Cal for Acidic Soils contains a highly soluble form of calcium, which is readily available for plant uptake or pH adjustment. 20% to 70% of your lawn fertilizer is wasted when soil pH is not balanced. It reduces stress, improves soil texture and aids in water uptake and releases trapped nutrients in the soil. Also contains humates for soil development. Apply at any time and combination with any other product. Great for establishing new seedings. Safe for people and pets.
