Jonathan Green 5M Mag-I-Cal Plus Alkaline

MAG-I-CAL PLUS® for Lawns in Alkaline + Hard Soil is a unique, multi-faceted, soil-enhancing food that lowers soil pH, loosens hard soil, and stimulates soil microbes. MAG-I-CAL PLUS® for Lawns in Alkaline + Hard Soil contains fast-acting sulfur which lowers soil pH to enhance nutrient availability from lawn foods. It also fortified with a patented, quick-releasing gypsum to help break up clay and compacted soil for better air, water, and root penetration into the soil. Additionally, MAG-I-CAL PLUS® promotes growth by increasing biological activity to aid in the release of “trapped” nutrients in the soil.
