That a bit hard to answer, in a sense yes in a sense no. Once a bed is well established more so, and even then you will likely use different types of teas to sway what kind of microbe activity occurs. Starting new you will need to establish the rhizome ecology which is generally determined by what kind of fertilizer or organic material the bed is mainly comprised of. You will also need to add back nutrients for the microbes to eat Whether its top dress, mulching cover crop, ferments, teas, or any mixture of them. The dirt gets washed out if you don’t and the life inside starts to die. With living soil we are trying to emulate what nature does from the ground up, no pun intended. So you will be performing some maintenance but you will not be discarding the dirt.
Fair warning there is a bit of a learning curve to living soil but there are many YouTube gardeners that can get you started. Searching basics of knf, jadam, or permaculture should get you to a pretty decent starting place.
When doing living soil you will need 5 gal container minimum but preferably 10+ gallon containers.
If you don’t plant to till, bigger is much better and you will likely want some kind of cover crop, such as clover. These are used as nitrogen regulators then mulched back into the top layer of soil to feed the microbes. Also you will definitely want a soil conditioner and wetting agent using this method. This reamends the soil after use. Aloe, yucca, or quillaja extract in addition to a worm tea.
Otherwise you will have to dump the dirt, amend, and repot. And from what I’ve seen is people have extra storage totes of dirt they are readying so that they have no downtime on their dirt in between harvests.
My method is mostly the first, with the addition of ferments and aerated teas, and a small bit of composting.
I will say that hydro has evolved very far and if that’s something you’re interested in it has a lot of advantages. Plants display toxicity and deficiency much quicker, soil pests are for the most part non existent, and an extremely wide variety of nutrients lines to pick from and they are a great deal more straight forward. Not to discourage you in anyway from your soil quest!
I tagged you in a post another user made for organic nutrients lines that are built off of the knf/jadam philosophies. A bit more expensive than a three part hydro series nute line but looks like a great all inclusive organic starter nutrient line.
