Look at an area that grows exceptional fruits/vegetables.
Do you think the soil is fresh? Nope, been recycled over and over, with more additives and beneficial microbestuff every day.
Buying new soil every go round is a waste of money. But hey, your pocketbook.
Hello,
I happen to work at a very very successful greenhouse and we never reuse soil. Its simply not a good idea - it isn't just a matter of nutrients, either. You have to consider disease, fungus, lack of nutriets, etc. We always throw out used soil.
