Poor soil that is hard and compacted is often the problem when it comes to growing a great lawn.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhen soil is too alkaline and compacted, air, water, and nutrients cannot get down to the roots, and the grass will not grow properly. Lawns thrive in slightly acidic to neutral soil with pH levels between 6.2 and 7.0. In soils with pH readings of 7.0 to 9.5, weeds thrive and the grass becomes light green and spindly. MAG-I-CAL® Plus helps to break up clay and compacted soils, improving root penetration and promoting growth by increasing biological activity and releasing nutrients trapped in the soil.\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eNatural soil food for lawns with alkaline soil\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLoosens hard soils\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePromotes air and water penetration for deeper rooting\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eHelps to rapidly lower soil pH to increase grass nutrient absorption\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNot sure which product is right for you?
