Worm tea - immediate uptake of 1-0-0 and 60 trace minerals. You can put a 1" layer of worm casings on top of your soil if you don't want to make tea; it will percolate down every time you water - for a month."Catipillars,weevils, grubs, & inchwormsick these things up & crush them if you find them on your plants. They can be turned into fertilizer by drowning them in the compost tea bucket." - Mountain Girl (Primo Plant-Growing Marijuana Outdoors)
I thought my book would have said but this is all i could find, sorry. I think that the worms are probably high in nitrogen.
