Jonathan Green MAG-I-CAL Calcium Fertilizer. MAG-I-CAL is a highly soluble form of calcium that helps to rapidly raise your soil’s pH, improving the health of your lawn by releasing trapped nutrients in the soil that feed the grass plants. Low soil pH causes weeds, moss, and bare spots to grow, while soil pH ranging between 6.0 – 6.8 will re-energize your lawn, increasing microbial activity, boosting your lawn’s color, reducing stress, improving soil texture and aiding in water uptake. Using MAG-I-CAL will also significantly improve your fertilizer’s effectiveness for a thicker, greener lawn with improved weed control. MAG-I-CAL comes in an easy to spread pellet form, can be applied anytime during the growing season, and is safe throughout the yard. MAG-I-CAL is also concentrated, meaning one bag of your back! MAG-I-CAL is the missing ingredient in your lawn care program that makes everything else work better!
