Our soil here (at our garden location anyway) is bad. Mostly sand for some reason, even though the area in general isn't "sandy". A previous owner must have come in with a shallow layer of topsoil over the sand. Looked like good soil when we started the garden last year. Burned off old stalks, tilled, planted, all seemed well. Over the course of the season and watering via sprinklers, the sand migrated up and the top soil disappeared. Now it's all just sand.
Had thought about taking off the first couple feet of sand and putting down good soil, but wasn't looking like we'd get a tractor in time to do so (my first posts, "why is it so hard to buy a tractor"). So wife was looking around and found the straw bale info, and we kind of got interested in trying it out. Now that I actually have a tractor and could take off the sand, I think we still want to try the straw bale method because it sounded so interesting.
I think I'll build a compost bin (large enough to get my FEL into), and try the bales this year. Worst case I'll have some compost for next year if I go back to traditional soil gardening.
