FREQUENTLY ASKED QUESTIONS
What is biochar?
Biochar is a stable, carbon-rich material made by heating organic biomass (like wood chips, crop residues, or manure) in a low-oxygen environment—a process called pyrolysis. It looks similar to charcoal but is used mainly for soil and environmental benefits, not as fuel.
How does biochar benefit soil?
Biochar has a highly porous structure that acts like a sponge in the soil. It helps retain water and nutrients, improves soil aeration, and provides habitat for microorganisms. Over time, this can lead to healthier plants and higher crop yields, especially in poor or degraded soils.
Is biochar environmentally friendly?
Yes—when produced and used responsibly. Biochar can lock carbon into soils for hundreds to thousands of years, helping reduce atmospheric CO₂. It can also reduce the need for chemical fertilizers and improve waste biomass management.
What is biochar used for?
Biochar is most commonly used as a soil amendment. It helps improve soil fertility, increase water retention, reduce nutrient leaching, and support beneficial soil microbes. It’s also used in carbon sequestration, composting, filtration, and some industrial applications
Is biochar the same as charcoal?
They’re similar but not the same. Both are carbon-rich and made from biomass, but charcoal is typically produced for fuel or cooking, while biochar is produced specifically for environmental and agricultural purposes, with properties optimized for soil and carbon storage.
How is biochar applied or “activated” before use?
Biochar is often “charged” or inoculated before application by mixing it with compost, manure, or nutrient-rich liquids. This prevents it from temporarily absorbing nutrients from the soil and helps it deliver immediate benefits to plants.
