Biochar has the benefit of providing multiple occupancy dwelling for soil
microbes, as well as being a carbon resource for the rhizosphere, which are
good benefits, though as I understand it the process of creating biochar
has a negative impact on the greater environment.

To me the greatest 'product' that we can use is humus which is compost, by
leaving it to nature to be the instigator of the 'burn' we get the ultimate
pathway to assisst nutrient assimilation. Personally I use Soil Food Web
grade composts (cultured by SFI - Soil Foodwed Institute based on the
science of Dr. Elaine Ingham a soil microbiologist - now retired she is the
Shigo of soil biology) https://www.soilfoodweb.com.au/

A SFI grade compost (anything man made usually is not compost) is created
as a site specific compost created in a laboratory based on providing soil
samples and then shipped, I would be surprised if the UK did not have an
SFI facility (facilities in NZ & the US)...

Here's an extract from an article in Prolandscaper e-news. It makes bold
claims but can anyone point me to the so called 'third party controlled
trials'?

<<Biochar is a porous, high-carbon form of charcoal that improves the
structure, aeration, water-holding capacity and nutrient retention of soils
of all types, and provides the perfect refuge for beneficial
microbiology. Carbon
Gold’s Tree Soil Improver is enriched with mycorrhizal and Trichoderma
fungi, seaweed and wormcasts and trees treated with it have been shown to
be resistant to pests and diseases including ash dieback, honey fungus,
acute oak decline and horse chestnut leaf miner in third-party controlled
trials.

The 250 treated trees, which were suffering from problems ranging from leaf
miner to blight, have all returned to full health.>>
