You didn't make any points worth discussing ... you simply regurgitated something you read ... and rather poorly I might add. Furthermore you did not even begin to address the question you were attempting to answer. Not following you JD. Is this your attempt to defend your statement concerning microbes producing the very same ions as synthetic ferts? Sorry JD, but one specialized group of bacteria converting atmospheric N2 to NH3 doesn't validate your all inclusive statement. He does .... where? All I see is a list of possible sources of inorganic ions. He makes no mention of where they come from .... does he? Yet that didn't stop you from misrepresenting what he wrote ... did it? Not an attack JD .... simply speaking the truth.
