Re: [compost_tea] Vermi tea EDTA & Hyacinth [1 Attachment]
On the smelly:
The anaerobic product that we are all familiar with (alcohol) is definitely
toxic to plants. It will also harm the civilizations of microbes living in
your soil. I would avoid introducing anything smelly to your soil, even as
a weapon. Add more oxygen and compost the fetid matter.
When and in what circumstances does the bad odor start? :-(

P.S. An article in the Journal of Environmental Engineering Science in 2006
(attached) argues that EDTA is an environmental pollutant. Based on my
reading, I wouldn't want to send such a substance toward the ground.
