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 my 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 made in advanced retorts using FSC wood. The wood is pyrolysed (heated in the absence of oxygen) in advanced retort kilns.
