100% pure biochar in 15kg sacks – Makes 150kg of Super-compost. Mix our biochar to home made or commercial composts for best results, or directly to soil if you just want to improve the quality of your soil.
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.
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, much more active than charcoal made by smouldering combustion.
We re-use the volatile gasses produced by pyrolysis as fuel for the process, these environmentally damaging gasses are combusted in the furnace at about 1100+ degrees.
Oxford Biochar produced is made from wood harvested from sustainably managed forests, and have a “Grown in Britain” licence (GiB-S-WM-5025) which involves a full annual audit of the ‘chain of custody’ from the forest to your bag of Biochar.
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.
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.
