There's a thousand variations of compost tea intended for different purposes. I tend to use just one simple recipe but there are tea recipes for fungal and microbial dominated teas and for veg, bloom, all purpose, what have you etc etc. You will find a ton of conflicting info & opinions online so IMO the best source to find compost tea recipes is in a book; I recommend checking out True Living Organics by The Rev. This book is the main source of all of my organic knowledge so read it and you'll be a fucking expert too lol. There is a tea sticky in organic that has lots of good info as well I would start there.So I've been researching tea. At first I found people are saying compost tea has no affect on plants. Then I stumbled across a thread of people adding things like azomite, oats, molasses, humic acid, fish emulsion, etc. Does anybody have any experience with this? Can anybody tell me good ratios to use for making tea if they are actually useful?
As has already been said compost teas provide some NPK benefit but their main function is to keep microbial and fungal populations active in your soil mix. The main ingredient of course is vermicompost and the fresher it is the better. Having a worm bin makes this an easy thing; bagged EWC will work too but will never be as active microbially as it is fresh out the bin. You can also make it with compost from an outdoor pile or composter bin. A form of sucrose like molasses is usually added to provide the micoherd with an easy food source. The bubbles are really what make it all happen: the microbes cling to the air bubbles and and get oxygenated which makes them hungry and horny. They begin to fight and eat and fuck each other until the populations reach a very high level. Then you dump it all into the soil and the party goes on til da break of dawn...
So to answer your Q in short form yes more aeration makes more microbes so you want it bubbling as violently as possible. Pushing a high volume of air through is always good but a cheap fish tank airstone will do for personal size brewing. Here's my all purpose tea recipe:
3-5 gal of clean water (no chlorine / chloramine)
2-3 cups EWC
1 tblspn molasses
2 tblspn kelp meal
3-5 tblspn Neptunes harvest liquid fish w/seaweed
Bubble for 36+ hours and serve
A fish tank heater helps if temps are on the low side. You want the water to be tepid; room temp or slightly higher is best.
Ratios do not need to be exact; this will never burn your plants and you can always add more water to dilute it if you need to.
