Mag-I-Cal® for Lawns in Acidic Soil in one bag has a pH adjusting power of up to 15 bags of limestone.
Jonathan Green’s Mag-I-Cal for Lawns in Acidic Soil contains calcium carbonate in a completely soluble form that is immediately available to adjust soil pH upwards. Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions.
Lawns thrive in soil with pH levels between 6.2 and 7.0. When the pH level of the soil is below this range grass becomes light green, weeds persist, and fertilizer nutrients are not fully absorbed. Mag-I-Cal Plus also contains humates to stimulate soil microbial life. When soil chemistry and biology are balanced, nutrients from lawn foods are not wasted and the grass will thrive.
Mag-I-Cal for Lawns in Acidic Soil is best applied during the growing season when the soil is not frozen. Spread the product on a dry lawn soon after mowing and for best results, rake the lawn vigorously prior to application. Irrigate the treated area after application for 15-30 minutes. Once watered, wait a day to mow the lawn to give the product time to activate.
