In a recent article published in the Edmonton Journal (, horticulturist Jim Hole talks about the various benefits of biochar as an additive to potting soils. Combined with high nutrient materials like potting soil, biochar can act like a sponge, soaking up water and nutrients and retaining them long after they would normally get washed away. Biochar also acts as a long-term carbon sink, keeping carbon atoms locked in the soil for thousands of years. From both a grower’s perspective and an ecological perspective, biochar just makes sense!
