Jonathan Green Mag-I-Cal Soil Food

Mag-I-Cal is specifically formulated for acidic soil with a pH below 6.2. Before applying, it is highly recommended to test your soil pH to confirm it is acidic, as raising the pH of soil that is already neutral or alkaline can be detrimental to your grass.

Yes, this product is safe to use on newly seeded or sodded areas. In fact, applying it during these times can help establish a better environment for root development and early growth.

While both products raise soil pH, Mag-I-Cal is significantly more efficient. One 18-pound bag provides the same pH-adjusting power as 15 bags of traditional limestone, and because it is immediately soluble, it works much faster to correct soil chemistry.

Yes, you should irrigate the area for 15 to 30 minutes immediately after application. This helps the granular product dissolve and move into the soil profile where it can begin working on the root zone.

Humates are organic substances that stimulate beneficial soil microbial life. By improving the biological activity in your soil, they help break down nutrients more effectively, making them easier for your grass to absorb.

You can apply this product in the spring, summer, or fall. The frequency depends on your soil test results; if your pH remains low, you can reapply as needed to keep the soil chemistry balanced within the optimal range.
