Neem Seed Meal Effects on Fungi & Microbe Colony

Hey yall! Per the title, how much of an effect will adding neem seed meal as an amendment to my super soil recipe have on fungal, and beneficial bacteria activity? I’ve come across a thread on another forum where Capulator (not sure who that is but seems important) states that neem seed meal inhibits the activity of microbes when incorporated into a soil. For those of you on here who use Neem Seed Meal. Do you see a huge decrease in beneficial bacteria/fungi activity? Should I omit the Neem Meal and go with something else?

Unless you're good with a microscope, you won’t really be able to know for sure. Neem seed meal is in a lot of soil mixes, and many people have had success with using it (I use it in my soil mix too). Did the person specifically mention why/how neem does this, and/or provide any source for this claim?

Sprinkle some moistened neem seed meal on the surface of your soil and let it sit for a couple cool, humid nights and see what happens, you will see the opposite of what Cap claims. It's not unlikely that it could inhibit certain microbes, but I bet you Capulator could not tell you which specific microbes are affected by it and how critical they are to growing cannabis.

I top dressed with neem seed meal for Fungus gnats.. It molded and the gnats loved it..

Part of the reason why I chose to include Neem Seed Meal was because of the widespread use in other people’s soil recipes. But you’re right there was no hard facts backing the claim, also part of the reason why I asked on here!

As it stands right now I don’t have a soil I can use to test other than what I have put in the garden. I’m attempting my first super soil build. I had a high thought that after reading the thread I was speaking about, that maybe it’ll affect the microbe activity during the cooking process.

Kis organics podcast episode 8 if my memory serves me correctly, Jim ( Clackamas Coot ) goes into detail on neem . Good luck
