Reading on the internet, people debate the effectiveness of adding microbes to the soil with microbial teas etc. stating that since microbes multiple so quickly, there really isn’t much of a valid use case for adding them in teas. And that also, so many of them are “invasive” and not local that it doesn’t make sense to allow them to breed out of control before adding.
From my understanding, organic soil is better on run 10 then run 1, assuming your adding organic fertilizers as needed to replenish.
What are all the reasons for this?
My own 2 cents worth here. As mainly an outdoor no till, organic grower.
The microbes are definitely important. But more important is somewhere for them to flourish. This environment is achieved through the combination of rich organic matter, organic carbon, microbial diversity and good soil aeration.
A microbial tea mostly doesn't supply these. It's just h2O and specific microbes. It lacks the same structure, organic matter / carbon and diversity.
I don't feel there's anything wrong at all with a tea. Only I'm of the belief you can achieve the same goal, if not potentially better. By adding the tea ingredients straight to your soil, instead of only by means of a tea.
It is better for the indigenous microbes.
I will always favor indigenous microbiology, before I introduce it. I believe in theory it's better in the long term. Both for the grower and native environment.
Organic Carbon is the most important thing for an organic soil.
Even for indoor soil, I'd choose whole organic materials as my source of microbes and nutrient, before considering a tea.
A tea should be treated as a top up tonic or supplement, in my opinion.
It's a quick temporary fix. Or to maintain.
Trivial information here. But bacteria can double in numbers every 30 - 60 minutes, given the ideal environment. Whether anaerobic or aerobic. We literally cannot keep up with them.
All we can do ourselves is provide the right environment for our plants to hopefully thrive.
Hope some of what I said was helpful.
All the best and good luck. Much love.
