Biochar

At Riverdale, I’ve spent over 10 years designing custom biochar kilns and consulting with farmers worldwide on producing and using high-quality biochar. I offer custom-built kilns or Zoom-based consulting to help you design and build small- to medium-scale biochar systems from waste materials on your farm or in your local community.

I help take the guesswork out of biochar—guiding you to decide whether buying locally sourced biochar makes sense or producing your own is the better option. Feedstock selection, particle size, loading methods, temperature, and burn duration all directly affect biochar quality. Get this right, and biochar becomes a powerful long-term tool for soil health and farm resilience.

What is Biochar?

Biochar is a stable, carbon-rich material produced by heating organic biomass—such as wood or crop residues—in a low-oxygen environment. When applied properly, biochar improves soil health by enhancing microbial habitat, nutrient retention, water-holding capacity, and long-term carbon storage.

Why inoculate biochar?

Fresh biochar is highly porous and acts like a sponge. If applied raw, it can temporarily absorb nutrients and microbes from the soil, reducing their short-term availability to plants. Inoculating biochar before use ensures it adds life to the soil rather than depleting it.

How do you inoculate biochar?

  1. Compost Charging Mix biochar into finished or active compost piles to enrich them with biology and nutrients.
  2. Liquid Inoculation: soak biochar in nutrient-rich liquids such as:
  • Compost extract or tea
  • Plant-based hydrolysates
  • Manure or diluted urine solutions
  • Low-dilution wood vinegar with added nutrients
  1. Animal Bedding Method Use biochar as animal bedding to absorb urine and nutrients, then compost the bedding before applying it to the field.

Rule of Thumb

Properly inoculated biochar should smell earthy—not smoky or ashy.

What is charcoal?

Charcoal is a carbon-rich material produced by heating wood or other biomass in a low-oxygen environment. It is primarily used as a fuel, filter medium, or odour absorber. Unlike biochar, charcoal is not specifically produced or conditioned for soil health applications.
