What do you mean by mix? You can't feed your plants and use beneficial organisms at the same time? Evidence supporting this? Still not seeing it...
Or do you mean just don't add straight/undiluted fertilizers to them before applying, or vice versa? And where's the eveidence for that? Microbes can survive rediculously toxic environments. Chemically, radiologically, extreme temperatures, shit even the near total vacuum of outer space for crying out loud. They're COMPLETELY dehydrated and inactive(essentially dead) by the time packaged and shipped for use. They'll stay that way indefinitely, in fact, and still come back to life given proper conditions. They're pretty god damn hard to kill actually. That's why it takes man-made things like fungicides, anti-bacterials/microbials, VERY high temperatures, or severe bombardment by high energy radiation to kill many of them.
The thread is starting to smell like fish(pardon the pun)...which is generally the time I like to pack up and move on...
Though it is true that bacteria and life in general can live in the most extreme environments, that is not what we are talking about here. You are comparing apples to oranges, or in this case soil biota to extremophiles.
The negative effects of ionic salts (ie nutrients) has been well established and documented for many years by a great number of scientists and studies. These effects have been studied for literally 30+ years and there are at this point probably several hundred studies confirm what me and others have stated on this thread. I'm not going to waste my time trying to re-find all the studies for someone that has obviously done zero research on this topic but here is a start:
"Plant Development and Harvest Yields of Greenhouse Tomatoes in Six Organic Growing Systems", North Carolina State University:
"Dynamics of soil microbial biomass and activity in conventional and organic farming systems", Soil Biology and Biochemistry Volume 30, Issue 6, June 1998, Pages 805-816:
"Conventional Fertilizers":
"Responses of soil microbial biomass and N availability to transition strategies from conventional to organic farming systems", Agriculture, Ecosystems & Environment Volume 113, Issues 1-4, April 2006, Pages 206-215
"pH regulation of carbon and nitrogen dynamics in two agricultural soils"
Soil Biology and Biochemistry Volume 38, Issue 5, May 2006, Pages 898-911
Plus a few other resources to check out:
Oh, not to mention there are all the other farmers and growers out there with microscopes that have observed the effects of fertilizers on ACT and have first hand experience with this subject confirming the negative effects of mixing fertilizers and ACT...
So, no you cannot mix fertilizers and beneficial organisms at the same time, at least not if you want your beneficial organisms or ACT to have any effect. However if you want to continue to pour money down the drain and completely negate the positive effects of your beneficial organisms be my guest......
