Yeah, reference please or evidence on ferments being nitrifying bacteria friendly. It would seem protien or carbohydrates varying from simple glucose to polyscacchrides seems to enhance microbe growth. And with a fast growing annual I only want certian cultures in my mix.
No comment on earth juice, MSDS lists "sea kelp, sugarcane molasses, oatbran, yeast" as primary ingredients.
I could see yeast being a potential food source itself for nitrifying bacteria as a food source like "bakers yeast" however it seems to be an odd way of approching it. Dead yeast is a food source for live yeast, so I assume microbes could use it.
I just thought it seems odd to use lacto or yeast to bump up microbe activity because they seem to supress microbe activity as in the case of fermented alcohol or pickling process .. I could see yeast also "limiting" excess simple carbohydrates but not to big a fan of the idea of it competing with mineralizing bacteria especially with exudates in the rhizosphere.
If anything I'm referencing Jeff Lowenfells and Dr Inghams work on microbes.. the majority of the AG products I've seen seem to focus more on aerobic bacteria that mineralize vs anerobes...
If it works for you.. cool.. I'm just trying to think out loud how this ferment style composting can be used.
