Mag-I-Cal® Plus for Acidic Soil 18lb

Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions. When soil is compacted or too acidic, air, water, and nutrients are unable to reach the roots, making it very difficult for grass to flourish. Jonathan Green Mag-I-Cal® Plus for Lawns in Acidic & Hard Soil contains calcium carbonate in a completely soluble form that is immediately available to adjust soil pH upwards. Additionally, Mag-I-Cal Plus helps to break up clay and compacted soils with fast-acting gypsum, humates, iron and amino acids. This improves root penetration and promotes growth by increasing biological activity and releasing nutrients trapped in the soil. Covers 5,000 square feet
