CarbonX Makeup


As a custom manufacturer that specializes in carbon release technology, we build our fertilizers around a biochar foundation.  The properties affecting the release and storage of biochar are gauged by the porosity, surface area, feedstock and temperature of the pyrolysis process. Carbon Earth Co produces biochars with different specs: variable feed stocks and variable pyrolysis termperatures.

Through our charging and densification process, we capitalize on the adsorbative nature of the biochar by homogenizing it with specific synergistic inputs depending on target plant needs.

At Carbon Earth, we utilize a patent-pending formula and manufacturing process that allows us to densify and enrich biochar with a multitude of inputs ranging from nitrogen, organic matter, micronutrients, or dormant biology.  This allows us to build and craft a variety of products for clients with the specificity of individual situations.

Biochar is a key component of our fertilizer science.  Biochar is the result of heating green waste (grasses, wood chips, compost, biosolids, litters) at high temperatures in an oxygen-free environment.  This reaction, known as pyrolysis, burns the lignin, carbohydrates, proteins, lipids, etc, leaving behind porous carbon structures.  Higher temperature reactions with less oxygen present results in a biochar with higher porosity.

Biochar is rated on the “porosity” of the remaining carbon after the burn.  At Carbon Earth Co, we utilize only a single source, temperature specific biochar. Our hardwoods are heated in an oxygen free reactor at extremely high temperatures.  This high temperature pyrolysis results in a biochar that is of the highest porosity, surface area, and ultimately, the most holding capacity. It sounds cool because it is cool.  It's for this reason that we're able to capitalize on the storage capacity to slowly release our macro and micro-nutrient complexes.


Due to the high surface area of our biochar, the adsorption capacities are massive (cation exchange capacity, anion exchange capacity).  That's a ridiculously complicated way to say it doesn't "soak up" ions, but rather "bonds" and holds onto ions. Carbon’s adsorption capacity allows it to bond and hold onto molecules (liquid, solids, or gasses).  The carbon can then release the molecules by either heat or agitation.

In the realm of turfgrass nutrients, the bonding of nutrient molecules to porous carbon means the nutrients can become “adsorbed” and then slowly released to the plants as the climate demands. While this works to slow the availability of nutrients, it also adds a certain level of unpredictability to the release of the nutrients.  To combat that issue, the biochar must become “charged” or coated with organic materials first, then, the biochar can be further reacted with additional nutrients, providing a more consistent, predictable release to the plants. As much as we'd like to take credit for this ingenious idea, we discovered it by accident.  And then we patented it.  And then University of Minnesota started to run trials on it.

Our "nutrification" process allows us to capture both anions and cations, however, in an effort to focus on complete and total plant health, we also utilize a proprietary infusion system.  Our system is unique in the sense that we have wide flexibility to infuse throughout the entirety of a granule, a very high volume of liquid materials.  For our fertilizer line, we utilize a specific RHPP (Root Hair Promoting Peptide) discovered first in Japan, before being manufactured for the global market.  We are the only granular fertilizer on the market featuring this RHPP Peptide.

The homogenization of biochar, charged through our densification process, infused with root hair promoting peptides, and homogenized with customizable inputs, we call our patent-pending CARBON RELEASE ROOT PROMOTING technology.  This unique formulation enhances the efficiency of inputs through a capture and release effect, as affected by the feedstock and pyrolysis temperature.
