If you are interested in “What is biochar is and how to use it” – please look at our dedicated sister site www.oxfordbiochar.org

We supply 100% pure biochar in fully recyclable bags, manufactured from hardwoods directly by us, not imported or re-labelled. Mix our biochar to any home made or commercial composts for best results, or directly to soil if you just want to improve the quality of your soil. The standard size is mixed grade 0-25mm most popular and usable in all applications.

Biochar is created through a non-combusting thermal destructive distillation of biomass in an oxygen free environment. This makes for a Biochar with exceptional internal surface area. Oxford Biochar produced is made from wood harvested from sustainably managed forests, and have a “Grown in Britain” licence which involves a full annual audit of the ‘chain of custody’ from the forest to your bag of Biochar.

We do not add mycorrhizae or fertilizers to our biochar, as soils harbour different species of mycorrhizae and have different nutrient deficiencies to cater for. You can add it straight to your soil or mix it with your favourite potting and seed compost.

How to use: Mix into the top 30 cm of soil in your vegetable patch in Autumn, Winter or at the start of Spring to restore soil fertility. You can also mix biochar to organic compost to make high quality compost.

Our recommendation is to dig it when planting because raw biochar needs to absorb nutrients and develop microbial root area relationships – this can take 2-7 months. This is why we recommend that you inoculate (soak, charge, activate, enrich) it with ‘wood-vinegar’ or fertiliser before using, see here: How to use wood vinegar

We recommend a minimum of 10% biochar in your planting medium. There is no recommended maximum application rate, so far studies have shown that the more you add the better the results. Whats’ best of all is that every time you dig in 1kg of biochar you take 3.6kg of CO2 from the atmosphere helping the planet to sequestrate carbon.
