MAG-I-CAL® PLUS Soil Food for Lawns in Alkaline & Hard Soil is a product that, with continued use, can LOWER the pH in your soil.

  • One 18 lb Bag covers 5,000 sq ft
  • Analysis is 18% calcium, 17% sulfur
  • Fortified with calcium sulfate dihydrate, humic acid, fast-acting gypsum, and humates
  • Great for LOWERING the pH in your soil

Product Description:
Mag-I-Cal Plus for Lawns in Alkaline & Hard Soil contains sulfur and calcium sulfate dihydrate, which lowers soil pH, is important to cell development, and is vital to many grass plant functions. Poor soil that is hard and compacted is often the problem when it comes to growing a great lawn.

When soil is too alkaline and compacted, air, water, and nutrients cannot get down to the roots, and the grass will not grow properly. Lawns thrive in slightly acidic to neutral soil with pH levels between 6.2 and 7.0. In soils with pH readings of 7.0 to 9.5, weeds thrive, and the grass becomes light green and spindly. Additionally, Mag-I-Cal Plus helps to break up clay and compacted soils. This improves root penetration and promotes growth by increasing biological activity and releasing nutrients trapped in the soil.

**Please Note: This is the product we carry that will help lower your pH. We have a similar product from Jonathan Green that will raise pH. 

Application Information:

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.

Fit 2025 Honda crv hybrid sport l
These fit my 2025 Honda crv hybrid sport-l perfectly. They are much more economical than having the shop replace them. I wish it said what the composition is- cotton or otherwise, because I have read you should oil cotton filters to work as intended. I didn't oil them amd so far haven't had any problems, but time will tell. They are a great value for the money and work as described. I would recommend these if you want to save some money on parts and labor for replacing your air filters. There are some good videos online that show you how step by step. I haven't noticed any odors or lack of durability since installing them.

Perfect Fit, Best Price
Style: 2.0L
The Honda parts sites that appeared in my search results mostly appear to be using the same software for their web-based storefronts and all charging $70+ to $80+ and shipping. These SCREW RHINO filters fit just like the OEM parts, are the same quality and cost about 1/4 of the price. I will not be buying these filters from the dealer parts stores ever again.
