Do Plants given Organic food still need commercial fertilizers?

[mistermaster]

I realize that going organic means not using any commercial fertilizer and pesticides. I have my worms for castings, my pile for compost, and I brew my own worm and compost tea. I apply castings, compost and tea regularly~ a week or so~

Just wondering though, do you think that I am providing enough food for my plants? Or do I need to supplement that with some commercial fertilizer?

Try going completely orgranic for a season, and see if you can compare the results and the growth to when you used it with commercial fertilizer. If there's not much difference, I guess you can stick with using organic.

ain't that quite expensive for a trial and error method sakura?

I was thinking about the lines on doing it at the same time using different garden plots but the same plants. Hmmm
