I found it interesting reading about the ability of compost when applied as a mulch to suppress some plant diseases. It is natural to assume that if the compost can do this then the compost tea would also. Then I read how the compost reduced the diseases in plants: by improving drainage and by preventing splash up. Compost tea can do neither of these things. Not saying compost tea is not good or helpful, I don't know. Just saying that when you know the how and why of things it can certainly be an eye opener on your own thought processes.
