Ok thank you for that info. I'm just thinking about the upcoming food shortage that they have been talking about and trying to think of the best way to start a garden here with having all of the rock's and colitchey in the soil around here. I'm sure that I'm not the only one that has been wondering how to manage that.I maybe tried it many moons ago in Mesa but I don't dare do it now - too many mice, rabbits & snakes that would just make a nice burrow here. I think if you're sure you don't have rodents or other pests it could be ok. Anyone in an urban area where there could be roof rats probably shouldn't. Maybe in another climate or if you have a large parcel where it's not near your barn or living spaces.
I know the previous owner here near Prescott had some of it but it was too near our shed with equipment in it so I did away with the bales. The wind here also just allowed those bales to collect terrible foxtail and other weed seeds.
