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

What You Need To Know

RAISES SOIL pH
Lawns thrive in soil with a pH between 6.2 and 7.0. When soil pH drops below this range, grass turns light green, weeds take over, and fertilizer nutrients aren't fully absorbed. Mag-I-Cal rapidly and efficiently raises soil pH to ensure healthy lawn growth.

USE IN PLACE OF LIMESTONE
One bag of Mag-I-Cal Soil Food has the pH adjusting power of up to five bags of limestone. Our soil amendment contains completely soluble calcium carbonate that is immediately available to adjust soil pH upwards.

ENCOURAGES NUTRIENT ABSORPTION
Mag-I-Cal enhances the ability of your grass to utilize nutrients in the soil. Lawn fertilizer is wasted when soil pH isn't balanced. Balanced soil chemistry ensures that nutrients are easily absorbed, promoting healthy lawn growth.

CONTAINS CALCIUM & HUMATES
Calcium is essential for vital grass plant functions. Mag-I-Cal provides readily available calcium for plant uptake or pH adjustment. It also contains humates, which 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. Measure your soil pH using the Jonathan Green Pro pH & Moisture Soil Tester (11100) or the Soil pH Test Kit for Lawns (11595).
