Your thread got me thinking, so I googled around to understand a broader range of people's opinions. So now I'm going to restate something, because people out there are confusing themselves. Yes, don't reuse soil, but Yes, recycle soil. There in lies the difference.
And in my experience with bagged soil, even the 20$ bags, is that none of them are balanced. So sometimes the latest garden pro with his hot new idea makes an o.k. bag of soil, but usually not. And that is the great thing about composting your own. Nature will make you a 100% balanced, 100% compost mix, for no money down.
People are always willing to spend the extra money for something they think will produce something better. Sure, I could get bat guano or whatever the latest thing is to get that extra nitrogen, etc. OR maybe just hop up my own compost... it's not rocket science.
And having been to Amsterdam many times,(where people don't talk, they smoke) I can tell you soil is soil. You wanna start dropping bombs then drudge your way into the art of hydro to smoke yourself blind. Next to hydro, soil is just soil. So have fun with it and watch yourself grow great crops in that dark brown nature that won't disappoint. And do it for free, nothing makes me wanna puke more than the commercialization of those things I hold dear.
