Where Our Soil Amendments Go to Work

How it works
CarboMatrix™: Carbon That Stays, Biology That Moves In
Biochar is a porous, long-lasting carbon. We charge it with premium compost and inoculate it with beneficial bacteria and fungi. The char stays in the soil, holding water and nutrients where roots can reach them and giving microbes a permanent place to live.
- Builds a living soilUSDA Certified Biobased biochar creates habitat for beneficial microorganisms.
- Improves soil structureBetter aeration and less compaction let roots grow deeper while water infiltrates and stays.
- Feeds beneficial microbesPremium compost fuels the soil food web for more efficient nutrient cycling.
- Unlocks and holds nutrientsLocks up heavy metals and makes macro- and micronutrients available when roots need them.
- Stimulates root growthA thriving soil environment drives faster root development and greater root mass.
- Increases water efficiencyPorous biochar holds water and nutrients in the root zone, reducing water needs.
BiocharUSDA Certified Biobased Carbon. Porous, stable, and long-lasting.
CompostPremium organics that feed the soil and charge the char.
MicrobesBeneficial bacteria and fungi, including a patented strain.
Customer reviews
From the Field
Switched from synthetics to an all-organic routine and my yard has never looked better! Mirimichi Green's Carbonizpn-g combined with ByoSpxtrum brought my lawn abundantly back to life.
Great soil amendment. I utilize it with all my topdressing programs.
Mirimichi Green is a major reason why my lawn looks the way it looks. I'm a big fan of all of their products! - Chicago
