The original shortform of your reply, in context, was an insult in that when I said I go by evidence you appeared to be inferring that I have no experience other than from using a computer. I do spend a lot of time on computers, yes, it's my job - I have also previously spent a lot of time growing food and studying the subject too.

Publishing 'farmers are clueless' as if it's fact is somewhat insulting. Did you forget to research that part?

Since you don't even think that rockdust does what I am clear it does do, you won't agree about the cluelessness. I mean that they are clueless about what I am talking about - which you appear to be backing up by sharing the link you shared that proports no value in rockdust - I and many others disagree. Even the tropical garden center I went to in Australia only recommended rockdust to feed certain types of trees. The claim that rockdust is of no value is not something I can agree with. If you think this and think that what I think is plane wrong, to the point where you say I am a snake oil salesman, despite me not even selling anything - then I'm sure you can understand how you are demonstrating the cluelessness from my POV.

I think you should slowdown on the rockdust.
