Perhaps, but a correct assumption nonetheless. That seems like a pretty all inclusive statement/question ..... no? Then I guess you have a problem with your own position. Your implications are crystal clear JD, and you damn well know it. Salts can and do kill microbes .... among other things. This is not an incorrect statement in as much as it does not clarify how salts can impact microbial communities. On the flip side, it is not any less (in)accurate a statement than you saying salts don't kill microbes ..... go figure. Is it? Perhaps it is a "critical component" to your argument, but not one with the issues which surround chemical fertilizers and their impacts on soils and soil biology. But if you insist, please list all the microbes that use these synthetic/organic/mineral plant nutrients and where they typically obtain them and what percentage of each of the three sources listed is utilized. And yet you still insist on spreading your uninformed bullshiit.
