About CarbonizPN-G Granular Soil Enhancer

Looking for Essential-G? You’re in the right place. CarbonizPN-G has replaced Mirimichi Green’s Essential-G starting in late 2024. You can learn how Essential-G was replaced with CarbonizPN-G or read on for more info on CarbonizPN-G.


CarbonizPN®-G is the spreadable, granular version of our flagship soil amendment, CarbonizPN. Our proprietary blend of USDA Certified Biobased Premium Biochar and blended compost is inoculated with the same strains of beneficial bacteria and fungi found in our ByoSpxtrum product, before being granulated into an easy-to-apply prill.

CarbonizPN-G helps build the critical organic content of your soil, allowing it to hold more moisture, reduce compaction, drive deeper root growth, and promote quicker green-up and recovery for grasses.

I’ve been using Mirimichi Green CarbonizPN-G as part of my soil-first lawn program, and I’ve been very happy with the results. I’m a big believer in improving the soil instead of just constantly pushing the grass with fertilizer, and this product fits perfectly into that approach. It spreads easily, works well with the rest of my lawn program, and the lawn has responded beautifully. The grass is thick, healthy, and has excellent color.

I have dealt with hard clay soil since we moved to our new home for about 5 years.I started using Carbonizpn about 3 years ago I apply it once a year.It has made the hard clay compacted soil looser and much more manageable the soil dosent stick in a big clump on the shovel.

I always enjoy using the products. My yard looked the best it has ever using them last year.

Using in lieu of aerating. In a suburb north of Houston. Thin layer of ‘soil’ under the turf, then clay. Grass was struggling. Lots of weeds. No matter the weed n feed, looked sad and patchy. Tried Mirimichi’s carboniz png two years ago. Lawn perked up! Now apply every year in fall and spring. Neighbors all tell me they’re impressed. Thick and lush lawn. I highly recommend the product.
