Biochar is something we have only just started to add to the garden beds even though the bag has been in storage under the house for the past year :/
I think that some of our beds are really lacking in organic matter, nutrients as well as the micro organisms that help make nutrients readily available for the plants.. I am hoping that the addition of the char, castings tea & the worm filled vermicast will help raise these levels for the next crop.. I have also started to feed the beds with a lot more horse manure not only to add organic matter but to also provide a ready source of food for the worms..
Have since learned that it is best not to add the Mycorrhiza to the compost tea as it probably wont survive.. You are better off adding it when planting out seeds, seedlings & larger plants..
The char we bought came from Black Earth Products at Kurwongbah, on the north side of Brisbane, not the Sunshine coast as I said in the clip sorry..
Chemical analysis of the biochar we bought..
The mycorrhiza we use came from..
A few sites I found helpful are
Black Earth’s ”About Biochar” page
U.S. Biochar Initiative
International Biochar Initiative
These are just 2 of the many I found & had a look through… A quick search on ”biochar” & ”syngas” will unearth hours of reading for you if your interested…
There are loads of biochar & syngas clips right here on YT as well..
I don’t endorse the above information or products, just sharing my sources 😉
