Many thanks for Ahmed Al-Rabaiai for organizing, filming this and for the good work on his PhD thesis.
Excellent information.
Hello Daniel, Thanks for sharing your vast knowledge on Biochar.
Gooooood information
Cheers!
Used to put the fireplace charcoal in the garden.
No wonder the grass was happy.
Thank you very much. This video has explained to me clearly and thoroughly what, why, and how questions before I dig more into biochar contributions to climate change. Again thank you so much, Sir.
Thanks for your kind words!
Great content
Thanks!
Excellent ✨
thank you
My pleasure.
I have had this coming up in my suggested videos over & over for months & months. I told myself that I would watch it... but only if the typo in the title gets corrects. So I paused the video after only a few seconds & I will return to finish it once the correction is made :)
Thanks AV very observative!
BTW love the banner in your channel!
That was quick - cool, now I can check out the video 👍🏻 :)
Thank you for sharing and to Ahmed Al-Rabaiai for his interesting coverage of the topic. I was wondering about a general optimum particle size of biochar, it was mentioned that the biochar should be made finer, do you know of any guidelines on particle sizes for biochar for general soil amendment for growing veggies? I've read that making biochar is too fine (powderised), it loses the structure that is beneficial for mychorrizal funghi, while I'd imagine having chunks of biochar too large wouldn't result in optimum soil texture
Yes, this is a bit counterintuitive. Apparently (not my data), biochar with granulometry from 1-2 mm works better as a soil amendment than when in fine pounder (
A 1/2 horse or larger sink garbage disposal works pretty good for me. Makes little chunks rather than dust.
I use an old sink mounted outside with a garden hose that grinds into a large rubber bucket. (Water is required to keep the disposal working properly) Then pour the slush into old plastic feed sacks. After 12 hrs or so the water will leak out leaving wetted char ready for inoculation.
If I'm not going to use it immediately I put the char in a cardboard box to dry further. When I'm happy with the moisture level, put in woven plastic feed sack for long-term storage.
Is there any recommended ratio how to mix compost and biochar? I have a metal barrel lying in the garden, so maybe I can do some biochar on my own ;)
Hi Sobie, starting from 10% compost reaching up to 50%. Or you can add the biochar at the start of the hot composting to get a very dark rich and stable compost product. The remaining charred material from bonfires or slow-burning heating stoves can also be used. Just don't use commercial charcoal because they have paraffin.
@@danielblac Thanks!
Explains why we have a love of bonfires. Heat and biochar for the soil
ممتازة جدا جدا

I think about starting a business producing this besides other bio environment-friendly products using compost and clean waste(wood, paper etc.).
Good luck! target house plant potting substrates, it's more profitable.
@@danielblac thanks a lot. First I'm going to do some testing in my own garden then if it's successful I'll make it better and sell it 😁
Thank Again what ratio can you suggest for cow waste mixing and how long can keep before use after mixing
If you mix the biochar with fresh cow manure you should compost it for two months before using it. It will improve the properties of the compost. If the cow manure is already composted you can use it straight away mixed, or by co-aplication.
@@danielblac thanks a lot lot. What mixing ratio do you suggest
Plz guid more on " how can i improve the water holding capacity of saindy soil"
Biochar is a good amendment for this, as is OM in general, but if your soil is too sandy you will need a high % to reach a sweet spot, it may take years.
at what point between the tree going into the earthen charcoal kiln and my pulling charcoal out of the dirt did some nefarious entity infuse it with paraffin?
please elaborate.
If your purpose is to sell charcoal for barbecues...
I'm planning to use burnt rice husk for my top garden soil. I heard that's it's carcinogenic which is very bad for the lung. Which one is safe? Burnt one or not?
The biochar should be safe for soil application, just don't eat it. If you completely burn it, it will become ash and not biochar.
@@danielblac it's like semi burnt. It's famous in Indonesia but I am afraid of health hazzard. It's cheap here compared to cocopeat (I consider cocopeat is expensive here coz not many in my area sell it and not many gardeners use it actually so they rather export them) so I was looking for the alternative.
lol... Mr. blackburn talking about char.
this was meant to be.
King James 488 I salute you!

Nice, send more info pls.

I don't have a PhD. But I've been in the soil with an undergrad degree. Other professor's in the US say this is hype
It is a good technology. I am doing research on it, it works wonders.
@Daniel Blackburn I was going to make my own. It's always better to get second opinion. I'm sitting on 250 tons of worm castings if you know a buyer in the US. I'll create a grant for one of your students. I need them out of the way. The come from Wonder worm in Nashville, Tennessee. They are not top shelf since this is an urban farm so you know they are fed feed grade nutrition. It's a worm farm more than for castings. Be there are a lot. Just let me know. I'll take them anywhere if the shipping is paid and they are 240 a ton. Or 200 for 20+ totes.
@@batchelerjr I am far from US, working in Muscat, Oman. I can't help you with your amazing stash of worm castings. Usually, they are the best organic fertilizers. We are testing biochar mixed with vermicompost here for salt-affected soils with good results. Good luck!
@Daniel Blackburn And you as well Professor!

hmm i missed another downside of biochar (sorry for being the annoying doom saying environmental scientist)
Polycyclic aromatic hydrocarbon will form based upon retention time in the pyrolysis reactor and the temperature as well as Polychlorinated biphenyl's that can also form and accumulate in the soil
Hydrothermal carbonization technology.
Bio-coal and then some
