I have a large dairy farm in my area that is processing its waste into compost & biochar. I plan on picking up some biochar to try on a few roses. Has anyone tried biochar, how did you apply, how much, what results did you see, etc?
Do let us know how it works for you.
A dairy operation near me, Fair Oaks, uses their waste in a bio generator to make gas to burn the moisture out of it. The process leaves a dry product. I've been unable to get any of it though. I'd be careful as cow manure has a lot of salts and can burn if too much is used.
Were I to gert any, I think I'd mix it with alfalfa and cotton seed meal.
Lucky You - certainly make use of it - Biochar has been a crucial ingredient in some of the most fertile soils on Earth. I will dig out some stuff and get back to you. Green with envy here!
Good question to check on Karl, also I want to check on pH effects of biochar as I've seen some info that it raises pH like wood ash. I've attached a link to the farm that produces the biochar, since they are market their compost & biochar to landscape & garden people, I hoping they have some good answers to these questions.

I just bought some biochar from BuyActivatedCharcoal house. It did not come with any instructions. I would like to try it on my newbies. I would like feedback on this product too.
The bio-char source that I linked aboved recommended mixing a 1/2" layer of bio-char in the top 6" of soil as the best way & amount to use. He said it needs to be worked into the soil because its very dusty & could be easily blown away by any wind. Below is one of the best articles that I've been able to find so far.
