Mag-I-Cal Plus Soil Food, Acidic Soil, 18 Lb.

Jonathan Green Mag-I-Cal Plus Soil Food is a granular soil amendment specifically formulated for lawns growing in acidic soil. Poor soil pH and compaction prevent air, water, and nutrients from reaching grass roots, resulting in weak, light green, spindly growth where weeds thrive. This natural soil food rapidly adjusts soil pH upward while breaking up clay and hard-packed soils, creating better conditions for healthy lawn growth and nutrient availability.

The product contains highly soluble calcium carbonate that is immediately available to raise soil pH, along with fast-acting gypsum, humates, iron, and amino acids. By feeding and activating beneficial soil microbes, Mag-I-Cal Plus improves the soil food web and maximizes plant absorption of lawn nutrients. One 18-pound bag covers up to 5,000 square feet and is safe for use on Bermuda grass and other turf varieties. It works well with any lawn fertilizer program and can be applied throughout the active growing season.
