[Stoves] Biochar and tea

[Frank Shields]

In my work with compost tea I measure 'shelf life' by keeping it at room
temperature (20 deg. C) and measure the decrease in oxygen (redox
potential). It needs a shelf life long enough to be aerobic when applied.
Some samples received are anaerobic when I receive them (in ice chest) and
others do not go anaerobic for weeks. The tea needs to be aerated long
enough to stabilize the carbon and microbe activity reduced.  Adding biochar
to compost tea would be an interesting experiment to see if it will last
longer. If the readily available soluble organic fraction is taken up by the
activation sites it could increase the shelf life (I think). Great idea for
a science project.  

 

Thanks

I really want this information as well please.  If there is anyone who would
like to participate in this research here I would support it and let's get
some answers.  Gerrie

Anyone know if there's been research done on how long compost tea-produced
bacteria will stay alive (or in a dormant state) in biochar after you
inoculate it?   

 

I know they say you should apply compost tea within 4 hours of brewing it,
but I'm wondering if you can make it last longer if you give it a happy
home.

 

Thanks,

 

Jeremiah
