Last year Nicci and me did a veggie garden, and every book I could get my hands on mentioned how good compost tea is to use. So we did. It did seem to help. A great publishing company to buy books from that supports the use of 'going organic' is :'RODALES'. their books are very comprehensive, although they basically deal with canning, growing, etc. I have not seen a book they publish dealing with tropical plants such as bananas, but the information they supplies me was useful nonetheless.
