Biochar

Biochar

Biochar is a carbon-rich soil amendment that enhances soil structure, boosts nutrient retention and improves moisture retention in the root zone. Produced in the UK from sustainably sourced hardwood trimmings, our raw Biochar is fine-grade (5–8mm), ideal for potting soil applications. It’s water-cooled after pyrolysis to reduce dust and improve usability.

Due to its high carbon content and porous structure, Biochar adsorbs nitrogen. For optimal results, pre-charge Biochar with a high-nitrogen input before use.

Benefits of Biochar for Your Garden

• Increases Nutrient Retention: Holds essential nutrients in the soil, making them more readily available to plants.
• Improves Soil Structure: Enhances aeration while boosting water retention capacity.
• Supports Beneficial Microbes: Provides a habitat for soil microbes, promoting healthier soil biology.

Additional Advantages 

• 100% natural and sustainably sourced.
• Ideal for long-term soil improvement.
• Helps reduce soil acidity over time.
• Sequesters heavy metals.

Application Rates

• Potting Soil Mix: Use 2–8% by volume (3–5% is typical)
• Add once when making a new soil mix

How to Use Biochar

• Immediate Use: Soak Biochar in water with 2–3g/L of Soy Amino N or other soluble high-nitrogen input to charge it.
• Soil Mix: Add 2–8% Biochar alongside compost, aeration, media, minerals and amendments. Allow the mix to complete the heating and cooling process. The nutrients released from this process charge the Biochar.
• Co-Composting: Mix into compost piles or worm farms at 5–20%. Biochar becomes charged during composting.
• Microbial Inoculation: Mix with inoculation-grade compost or powdered microbe blends such as Biosys. Pre-charge with soluble nitrogen for best results.

Note: Excessive Biochar applications can lead to nutrient sequestration and reduced nutrient availability.
