Gardeners - it seems like a no-brainer, but really, you can collect great fertilizer from the manure pile at your local riding stables, even if you reside in a suburban/urban area. Collect from the bottom edge of the pile, where the manure is already aged and dried. Take many small bins or boxes with you, since these are portable, whereas a large tarp or container would not be. And of course, wear boots and bring a shovel. If possible, back your vehicle right up to the pile.

We do this too and give to our neighbors. It's great fertilizer.
