Welcome to our Trade & Partner page for the bulk (pallet load) purchase of biochar.
Contact us for quotes on bulk bags, pallet delivery, VAT invoices and account terms.
Our standard grade of biochar is 0-10mm granule. All our biochar is made in advanced retort kilns using UK grown FSC certified wood. For bulk quantities of our sieved 0-2mm grade, please contact us.
Biochar is used to improve crop and plant growth. Add biochar to soil and compost to improve:
- Water retention
- Nutrient supply to roots
- Decrease nutrient run of
- Support microbes and AMF (mycorrhizal fungi)
- Support the formation and stability of colloidal humus
- Improve soil tilth

- 10 Kg bags (approx 30 litres), 30 per pallet
- 1 m3 dumpy bags (weight 300-500 Kg)
Environmental benefits include:
- Carbon capture by locking carbon in the soil for hundreds of years – offsetting your carbon footprint
- Reduced NOx and methane soil emissions
Where to use biochar
- Raised beds
- General gardens
- Add to compost* (see below)
How to apply biochar
The most powerful biochar benefits involve interactions with the root zone. It follows the best place for biochar is in the root zone. Our recommendation is to dig it when planting (eg seed drills, tree holes or when cultivating the soil. This is not always possible (nor desirable if following no-till regime!) and biochar benefits have been shown when used as a top dressing or when lightly hoed into top few cm soil.
We recommend (along with most of the biochar scientific community) that you 'inoculate' (soak, charge, activate, enrich) your biochar before adding it to the soil. The simplest method is to add biochar to your composting process. However, if you prefer to buy a 'ready-made' activated biochar - please see our SF60 product page.
How much biochar should I apply to soil?
The range is 0.5-5 Kg/m2 (5-50 t/ha), around 1-10% by volume. Heavy clay soils tend to benefit from higher application rates.
Annual plants – biochar should be sprinkled onto the beds/containers then hoed in to ensure all char is fully mixed with your soil/compost.
Perennial plants – 500g of char should be sprinkled into the planting hole alongside a mycorrhizal inoculant (eg Root Grow) before backfilling the hole with soil.
Our biochar is 100% made in the UK using wood from UK FSC grown woodland. The wood is pyrolysed (heated in the absence of oxygen) in advanced retort kilns.
