"In addition to the beauty of mushrooms, fungi provide a critical part of nature's continuous rebirth: fungi recycle dead organic matter into useful nutrients."

I've used "Black Kow" composted manure and mushroom compost since I began gardening, and wouldn't trade either of the two for anything else on the market (save for "homegrown" compost). The occasional mushroom medley or funky fungi is only proof positive that it's potent properties are positively prevalent and "working" to improve my soil. "shrooms" is a good thang!
