SCD,
I have never gone through the trouble of getting a pump and creating an aerated compost tea, so I cannot speak to it with any firsthand knowledge. I make use of traditionally made compost tea and mycorrhizae. It works very well for me.
For me it is all about the quality of what is being used and about diversity in regards to what is going in the soil. So I will use buffalo to create a compost tea, or really rich worm castings, cow compost from a really good organic farm, and so on. When it comes to buffalo I use “BuffaLoam Organic Plant Food”, it's just organic buffalo compost and Norwegian seaweed. In my opinion mycorrhizae is essential.
Getting a pump and making aerated compost tea, that sounds like it could be beneficial, more oxygen in the mix. It seems like it could be helpful in situations where you are creating and building up soil that is newly made and hasn’t been well established.
Thanks Invasive, So far I feel like I've been learning to walk on a high wire, one slip & everything is ruined but it is going to be worth it. Why in particular did you settle on BuffaLoam? I've settled on some Better Organix products to begin with. Am also using Mycorrhizal fungi anytime I go near a root ball/seed. One other reason for the air pump is to rid my plants of chlorinated water in 1 hour, as presently I don't have a water butt & I have to use mains water.
