🌿 Biochar FAQ

✅ How is biochar made?

Biochar is made by heating organic material like wood, crop waste, or manure in a low-oxygen environment, a process called pyrolysis. This converts biomass into a stable form of carbon, locking it into a solid structure that resists decay.

✅ How does biochar work?

Biochar works by improving soil structure, retaining nutrients and water, and supporting beneficial microbes. In ponds or wastewater, it binds impurities and balances microbial ecosystems.

✅ How does biochar help in carbon sequestration?

Biochar stabilizes carbon for hundreds to thousands of years by locking it in a solid form that won’t decompose or re-enter the atmosphere. This makes it a powerful tool for long-term carbon sequestration.

✅ How does biochar sequester carbon?

Through pyrolysis, carbon that would normally return to the atmosphere via decomposition is instead captured in biochar’s porous matrix. When applied to soil or other systems, that carbon stays put for the long term.

✅ How does biochar remove CO₂ from the air?

Biochar doesn’t directly absorb CO₂ from the air. Instead, it locks in carbon from biomass that originally pulled CO₂ from the air through photosynthesis—making it a negative-emission technology.

✅ How does biochar work and when doesn’t it?

Biochar works best when activated before application. It may not perform well in sterile or already high-carbon soils without microbial partners.

✅ How does biochar capture CO₂?

Biochar captures carbon indirectly by stopping biomass from decomposing into CO₂. It captures carbon in a solid, stable form—not as a gas absorber like activated carbon.

✅ How is biochar prepared?

After pyrolysis, biochar should be screened, rinsed, and optionally inoculated to maximize effectiveness.

✅ How is biochar formed?

Biochar is formed via thermal decomposition of organic matter in a low-oxygen environment. This process alters the material’s chemical structure into a carbon-rich lattice.

✅ How to make biochar?

You can make biochar at home using a small kiln, pit method, or retort system. Always ensure low oxygen during burn to create quality char.

✅ How to use biochar?

Biochar can be used in gardens, lawns, compost piles, livestock bedding, ponds, filtration systems, and manure pits.

✅ How does it work in soil?

In soil, biochar improves nutrient holding, aeration, and water retention. It boosts microbial activity and supports long-term soil fertility and carbon storage.

✅ How much biochar per square foot?

For gardening, apply 1/2 to 1 inch of biochar (roughly 5–10 lbs per 100 sq ft), then blend it into the top 4–6 inches of soil.

✅ How much biochar per acre?

Typical application is 2–10 tons per acre, depending on soil condition and purpose (carbon storage, fertility, remediation).

✅ How much biochar per gallon of soil?

A common recommendation is 10–15% biochar by volume. That’s about 1–1.5 cups per gallon of soil in potted plants or raised beds.
