Soil by definition is sand silt and clay - nothing else. The less expensive bags of potting mix often have no sand silt and clay but instead are 100% organic matter with some perlite - this is not a good mix for organic amendments.
By real soil I meant not a sterile growth medium such as coco or peat which completely nullifies all organic amendment use - I didn't mention anything about getting this outdoors but if you know how to properly compost it will not be a problem as all bugs are killed otherwise definitely don't contaminate. And for gods sake don't go with a sterilized soil as none of your organic amendments will ever be broken down. I prefer Happy Frog personally.
When amending soil - Remember, no bacteria and fungi, no nutrients.
What *I* use, is known in the trade as a 'sterile' mix, basically peat moss and perlite. I start to consider it 'soil' when I add EWC. This is from 2 indoor worm bins that I run.
IMO, peat is totally organic. It is nothing but broken down spagnum moss, which I also used to use when I grew Platycerium ferns (Staghorn ferns). It works great with organic amendments, it works great with chemical nutrients. You just need to understand and know how to work with peat moss. Some sort of lime, usually dolomite is the key here. Peat is great for an organic grow. Coco, I have 0 experience with, so IDK.
I have never bought a bagged soil or soil mix. But, from what I've read AFA ingredient lists, just about all of them are peat based mixes. FFOF, Happy Frog, Sunshine #4, ProMix, ................. All can be worked with, just mind the pH of the peat with lime.
I'm really not trying to argue or anything. I HAVE a compost pile and make use of it. I also grow my own bacteria and mycorrhizae, using the worm bins for the bacteria and Alliums (Garlic, onions, Leeks, Shallots), for the Myco's.
I just make sure that outside stuff (where there is a natural balance), stays outside and doesn't make it inside, where it could be a perfect storm. Like, say, fungus gnats from bagged soil being stored outside type of thing.
Am I making any sort of sense here?
Not sure myself any longer.
We are in agreement for the most part, I'm just adding my experiences from growing *stuff* over the last 40 years +-.
