What is Biochar?

Biochar is a highly stable, carbon-rich form of charcoal produced by heating organic material (like wood, agricultural waste, or biomass).
Here are 6 key benefits of biochar:

Improves Soil Health
Biochar enhances soil structure, improving aeration and drainage. It also increases soil pH, making it more favorable for plants to absorb nutrients.
Boosts Nutrient Retention
By increasing the soil's cation exchange capacity (CEC), biochar helps retain essential nutrients like nitrogen, phosphorus, and potassium, reducing nutrient loss through leaching.
Enhances Water Retention
Biochar's porous structure helps retain water in the soil, making it particularly beneficial in drought-prone areas by reducing the need for frequent irrigation.
Reduces Greenhouse Gas Emissions
Biochar sequesters carbon for hundreds to thousands of years, helping mitigate climate change by locking carbon into the soil instead of releasing it into the atmosphere.

Promotes Healthy Plant Growth
With improved nutrient availability, enhanced water retention, and better soil structure, biochar helps plants grow stronger, faster, and more resilient to environmental stresses.
Reduces Soil Contaminants
Biochar has the ability to absorb and neutralize harmful pollutants, like heavy metals and toxins, from the soil, improving soil quality and health.

Frequently Asked Questions (FAQs)

1. What is biochar?
Answer: Biochar is a carbon-rich material created by heating organic materials (like wood, agricultural waste, or biomass) in a low-oxygen environment, a process known as pyrolysis. It's primarily used as a soil amendment but also has applications in energy production, water filtration, and carbon sequestration.
2. How does biochar benefit my soil?
Answer: Biochar improves soil health by enhancing water retention, increasing nutrient availability, improving soil structure, and promoting healthy microbial activity. It also helps increase the pH of acidic soils, making them more plant-friendly.
3. Can I use biochar in my garden?
Answer: Yes! Biochar is great for gardens. You can mix it into the soil, use it in compost, add it to potting mixes, or even use it as a mulch to improve soil fertility, moisture retention, and root growth.
4. What’s the difference between biochar and charcoal?
Answer: Biochar is a type of charcoal but is specifically produced for environmental and agricultural purposes. It is made at lower temperatures and in a controlled, low-oxygen environment. Charcoal, on the other hand, is typically produced for fuel and may not have the same porous structure or long-lasting carbon sequestration benefits.
5. How much biochar should I use in my garden?
Answer: For garden beds, it's recommended to mix in about 5-10% biochar by volume into the soil. For potting mixes, aim for 10-20%. Start with a small amount to see how your plants respond, and gradually increase it if needed.
6. Can biochar harm my plants?
Answer: When used correctly, biochar is safe for plants. However, if applied in excess or without "charging" it (soaking it in water or nutrient-rich solutions before use), it could draw nutrients from the soil, temporarily affecting plant growth.
7. How do I charge biochar?
Answer: Charging biochar means soaking it in a nutrient-rich solution like compost tea, liquid fertilizer, or even water mixed with organic matter (e.g., soil or compost) for a day or two before use. This ensures the biochar doesn’t leach nutrients from the soil.
We sell fully charged( do not add to garden not charged )
8. Can biochar help with climate change?
Answer: Yes! Biochar helps combat climate change by sequestering carbon in the soil for hundreds to thousands of years. It reduces greenhouse gas emissions by locking away carbon that would otherwise be released into the atmosphere if the organic material were left to decay or burn.
9. Can biochar be used for water filtration?
Answer: Yes! Due to its porous structure, biochar is effective at removing contaminants from water, including heavy metals, organic pollutants, and even some pathogens. It’s being used in water filtration systems and in wastewater treatment.
10. Is biochar safe for the environment?
Answer: Biochar is environmentally friendly when produced and used properly. It helps improve soil health, reduces greenhouse gas emissions, and can be made from waste materials like agricultural residues, turning them into a valuable resource.
11. Can I make biochar myself?
Answer: Yes, you can make biochar at home using a small pyrolysis unit or even a simple kiln. The process involves heating organic material (like wood or agricultural waste) in a low-oxygen environment. However, creating biochar safely requires proper equipment and attention to safety, especially to manage high temperatures and gases.
12. What types of materials can be used to make biochar?
Answer: Biochar can be made from a wide range of organic materials, including wood, agricultural waste (corn stalks, rice husks), forestry residues, manure, and even food scraps. It’s important to avoid using treated or painted materials, as these can release harmful toxins when burned.
13. Does biochar have any other industrial applications?
Answer: Yes! Beyond agriculture, biochar is being explored in fields such as building materials, where it’s added to concrete for improved thermal insulation, and in energy production, where it can be used in bioenergy systems as a renewable fuel.
14. How long does biochar last in the soil?
Answer: Biochar is highly stable and can last hundreds to thousands of years in the soil, continuing to sequester carbon and provide soil benefits over time.

About David - from the New Forest Biochar Company

I was born in London and the early 60’s but was lucky enough to move to the idyllic countryside of Dorset where my absolute love of nature and the countryside was born and crystallised, I was its not unfair to say an oddball but I’m happy with that and do not compromise.
Having joined the Royal Navy at 18 and served a number of years I then entered the world of corporate business and frankly didn’t fit fortunately.
I escaped that world and was fortunate during this period to meet someone prepare to cope with/ guide / mentor/ care for and encourage a severe ADHD er in the guise of my wing lady of over 40 years, the mother of our incredible 3 children and the glue that holds us together when the idea a day Dave strikes.
We have spent the last 18 years running our logistics company to support everything we have done and travelled and worked remotely in our camper, we’ve survived Brexit and covid and everything in between , all the time I knew I wanted to do something tangible and physical that made difference to the environment and the future of the planet and then I found biochar- a game changer.
