Thrilling, even. I particularly liked the part where it said "An error occurred while processing your request.Reference #50.26bf3b17.1354910575.91e769fe"
Life-changing.
Seriously though, the problem with the argument "N is N" is one side is arguing from a flawed understanding of science.
Yes, of course anything is equal to itself. Any atom is identical to any other atom of the same type, presuming of course we're not talking about isotopes or ions.
But this is a very narrow view and creates a fundamental misunderstanding of the very nature of... nature. You're not likely to ever wander around and find a solitary Nitrogen atom drifting around. With the exception of your noble gasses, atoms are almost always stuck to other atoms (making molecules). Saying that all Nitrogen is the same for plants is like saying all Oxygen is the same for humans. There's TONS of oxygen in water. Try breathing it sometime and let me know if you still think "oxygen is oxygen". It doesn't matter how much water you get in your lungs (or your stomach or any other type of contact) you will NOT get enough oxygen in your blood to survive unless it's in a very specific, useful form for your body. Our body is only capable of absorbing oxygen effectively through a single method and in a single form (O2, gaseous oxygen). (Yes, I did see "The Abyss" and I'm aware of hyper-oxygenated fluids. The point still stands.)
Plants are no different. They need relatively precise proportions of their elemental nutrients, and in relatively precise forms. They're much less picky about that than we are about our oxygen, but they're still rather picky. They'll actually grow differently based on the type of Nitrogen you give them, and there's a lot more than just Nitrogen (or Phosphorus, or Potassium) they need to thrive and each of those can be supplied in multiple different forms.
So yes, Nitrogen is Nitrogen. But saying that in terms of plant science only serves to illustrate a fundamental flaw in your understanding of science as a whole, and plant science in particular.
You think some of these people can grow bamboo?!
