Jonathan Green Mag-I-Cal Plus is a natural soil food formulated specifically for lawns growing in alkaline and hard-packed soils. Many homeowners struggle with compacted clay soils and overly alkaline conditions that prevent grass roots from accessing water, air, and nutrients. This product addresses those challenges by lowering soil pH and breaking up heavy, compacted earth, creating a healthier environment where grass can thrive.
The granular formula contains sulfur and calcium sulfate dihydrate, which work together to reduce soil alkalinity and improve soil structure. By loosening compacted soils and increasing biological activity, Mag-I-Cal Plus releases nutrients already trapped in the soil and promotes deeper root penetration. The result is stronger grass growth, better water infiltration, and improved overall lawn health.
