Jonathan Green Mag-I-Cal Soil Food for Lawns in Acidic Soil - Grass Amendment (5,000 Sq. Ft.)

About this item

• RAISES SOIL PH - Lawns thrive in soil with pH levels between 6.2 and 7.0. When soil pH is below this range grass becomes light green, weeds persist, and fertilizer nutrients aren't fully absorbed. Mag-I-Cal rapidly and efficiently raises soil pH.
• USE IN PLACE OF LIMESTONE - 1 bag of Mag-I-Cal Soil Food has the pH adjusting power of up to 5 bags of limestone. Our soil amendment contains calcium carbonate in a completely soluble form that is immediately available to adjust soil pH upwards.
• ENCOURAGES NUTRIENT ABSORPTION - Mag-I-Cal increases the ability of your grass to utilize nutrients in the soil. Lawn fertilizer is wasted when soil pH is not balanced. When the soil chemistry is balanced, the nutrients are able to be absorbed.
• CONTAINS CALCIUM & HUMATES - Calcium is vital to many grass plant functions. It's readily available in Mag-I-Cal for plant uptake or pH adjustment. Mag-I-Cal also contains humates to stimulate soil microbial life and root development.
• COMPLETE COVERAGE - This 18 lb bag covers up to 5,000 sq. ft and can be used in spring, summer, or fall. Use the Jonathan Green Pro pH & Moisture Soil Tester (11100) or Soil pH Test Kit for Lawns (11595) to measure the soil pH of your yard.
