The Power of Biochar

What is biochar?

Biochar is a carbon-rich material created by heating organic matter, like wood or plant waste, in a low-oxygen environment.

When added to soil, biochar enhances water retention, supports beneficial microbes, and prevents nutrient loss, making it a powerful tool for sustainable land management.

Digging deeper…

Biochar is produced through a process called pyrolysis, where organic materials are heated at high temperatures (typically 300–700°C) in a low-oxygen environment. This process prevents combustion, instead breaking down the material into biochar and releasing bio-oil and gases that can be used for energy.

At Circle Forestry, we create biochar using wood waste from arborist projects, ensuring trees are recycled into a valuable, soil-enhancing resource.

Biochar: A powerhouse soil ingredient

  • Minimizes nutrient loss for healthier soil

  • Balances soil pH and redox potential (Eh)

  • Supports a thriving microbial ecosystem in the soil

  • Improves water retention and conservation

  • Enhances soil resilience by adding long-lasting carbon, reducing degradation

  • Boosts plant growth, especially in nutrient-deficient soils

Beyond Soil; What else can biochar can do?

  • Mitigates wildfire risk by converting excess fuel loads into carbon-rich, water-holding soil amendments

  • Prevents carbon from being released into the atmosphere as CO₂. Instead, it locks carbon into the soil, reducing greenhouse gases and improving soil health at the same time.

  • Helps combat drought by retaining moisture in the soil

  • Reduces fertilizer dependence by holding nutrients in place

  • Restores depleted soil by creating a healthy environment for beneficial microbes

  • Improves manure and compost quality by reducing odors and supporting good microbes

  • Remediates polluted soil by trapping heavy metals and contaminants while minimizing odor

  • Enhances sustainable building materials when used in cement, plasters, and other applications

  • Promotes animal health through improved feed and bedding applications
