I can agree to disagree.
Let me ask you this do you organic growers need to replace your soil after growing? Nope just keep adding more organic ferts to keep it rich can be used as long as you want.
Do you growers using salt based ferts replace your soil after a grow?
From my understanding almost always.
I don't grow in dirt but I do have an understanding of nutrients. Organic and salt based nutrients are not the same. Yes both can pollute the environment in excess.
They do not leave the same amounts of unusable waste. Almost all salt based ferts contain sodium. Sodium is only used in trace amounts and a buildup will hurt soils. This can take a long or short time to happen depending on the amount of sodium and the amount of dirt it's out into and also the drainage of that soil.
They are exactly the same. I make components for black powder (potassium nitrate) in a nitre bed using organic material. I could take that same material and fertilize with it. An ion is an ion.
They aren't real salts, these "synthetic" fertilizers. The only thing "synthetic" about them are the chelating agents, as mentioned before. Otherwise, they are just bonded ions, same as organic.
Don't get me wrong, I see where you and others are coming from exactly. I use all raw organic materials, but not because of "salts".
Organic releases much slower as it has to be broken down. Less immediate nutrition, more over the long run. I'm learning this the hard way on the hydro bucket lol.
Organic amendments are really only meant for soil structure. "Synthetic" fertilizers are immediate nutrition that can be used in any medium via chelation, but they don't hold like organic. Beyond that, there is no difference between the ions.
