As a custom manufacturer that specializes in carbon release technology, we build our fertilizer around a biochar foundation. The properties and characteristics of release and storage of biochar is gauged by the porosity or surface area resulting from pyrolysis. Carbon Earth Co produces and maintains biochar with different specs: variable feed stocks and variable pyrolysis termperatures.
We capitalize on the porosity of the carbon by filling it with specific synergistic inputs depending on your needs.

Carbon Earth uses specialty equipment to for particle size reduction, with the ability to take a variety of materials from 1/2" to micron sizing.
Densification & Enrichment
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 a specialized biochar. It's 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). 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.
Biochar’s density allows it to alter the physical structure of soil. Biochar has a density of 1.34 g cm−3 , depending on the temperature of the pyrolysis. This low density when added to soil, has the ability to lower the overall bulk density of soils. A soil with lower bulk density offers less resistance against development of roots. Also, soils with lower bulk density have a higher porosity, or soil surface area. A greater soil surface area results in a soil with higher cation exchange capacity which can hold onto nutrients more efficiently.
