Liz/ Wayne/ Markess, I do not think we have "to prove it scientifically". Chemical farming does not do this, or who would agree to putting highly dangerous chemicals in your land, your crops and your self.
They buy a proposal of self interest. The chemical salesman says words to the effect of: "Pay me a very large amount of money and this stuff I am selling will increase your yield/ you profit/ make your life easier or simpler etc." We have to have people out there selling the self interest of: "Pay me a modest amount of money, much less than you currently pay the chemical man and I will put this funny looking thing in your paddock that lets me communicate with your land and tell what is happening and every now and then, I will ship you some stuff, which you dilute and run through a flow form and then spray on your paddock at the time I tell you." We do not have to be evangelical or even mention RS/ BD/ Magic/ Tooth Fairy/ Cow's Horns.... We just gotto sell self interest, that is what the Chemical heads do. I am a keen observer of people and I think we only try and explain something when we do not fully believe it our selves. When we have full confidence, we do not think of it as needing explaining and our confidence carries on to the next person and they do not need explaining either... Gil
