He is in the IT department because there was no work in horticulture.
Also, he graduated many years back and has not been keeping up with the newest studies I don't believe.
You ever see that commercial about some type of sugar that's supposed to be better or organic?
It's very simple....it says the human body cannot distinguish if sugar came from sugar cane, corn, or anything else for that matter. All the body knows is that it's getting sugar. In one's mind and/or taste buds, it is different but where it counts the most, there is no difference.
Since plants do not have a brain, nor do I think taste buds....then to them, there is no difference if nitrogen came from Mars, Jupiter, the ground or some animal's behind.
Scientists want us to believe there is no GOD yet some of them are now looking for the so-called GOD particle.
30yrs ago, eggs and pork were bad for us, today, eggs don't have that much cholesterol as once thought and pork is "the other white meat".
Now lets go back to humans and deadly chemicals, I can give you some drink laced with a deadly amount of some type of chemical and you'd never taste, see it, nor smell it and die within seconds. So if a human that has the sense of smell, tatse and sight can't tell the difference between fruit punch that has no deadly chemicals in it or one that does, then how can plants?
Truth is, some guy with a microscope is the only one that can, other than that not much else can.
It doesn't take rocket science to figure some of this stuff out, just simple good old common sense.
The cycle between scientists and their findings will continue as always...maybe because the government wants it that way. The cycle I'm referring to is today something is good for you, ten years from now it causes cancer or today something is bad for you and ten years from now, it wasn't that bad afterall, etc, etc, etc...
