You poorer sap, mallcontent. That's not what I have been asking. Nice name-calling, BTW.

Nothing in this ridiculous, more than 12 year old, article says anything about the Minnesota, S. Dakota, Wisconsin, Illinois, and Nebraska farm run-off that enters Iowa and continues downstream. Were they not farming in those states in 1999?

Do you even have a clue about farming methods of today?

You posted that Iowa fertilizers have been identified in the gulf; your original claim. Nice try at ducking that issue. That is what you were questioned on and what we are still waiting for you to prove. That is hardly nitpicking. This is just one more generic statement about gulf pollution. I asked you before about Iowa runoff that enters Missouri, then enters the Miss. River. How do we know what is Iowa's and which is Missouri's; or Minnesota's fertilizer for that matter?

Do you even know where the Missouri river starts and which and how many states it flows through picking up run-off pollution? It enters the Miss. near St. Louis, above Cairo, Ill where the Ohio dumps into the Miss. Your "authorities" in this article don't even mention the Missouri River and its sources. There is one hell of a lot of fertilizer use in Montana, N & S Dakota, and Nebraska for your experts to ignore as sources!

How much more of a moron are you going to demonstrate yourself to be? The Missouri River is only about 190 miles shorter than the Miss Rvr; and doesn't even get honorable mention from your obviously agendized authors. The word "Missouri" is mentioned once in your article....and it wasn't the river! Such wizardry! LMBBAO!

You're absolutely correct.   What I provided is something to show it can be and has been done.  If you really wanted to know, as opposed to just being a pest, you could find later, more detailed articles that would show they can measure it with even more precision now, thus reinforcing my original statement about what percentage of the nitrogen in the Gulf that is from Iowa.

Ignore BS.   He's in his nit picking, changing the rules, being a pest mode.

Ignore my last comment.   BS just can't grasp how this is done so he brings in superfluous questions and comments about the length of the Missouri, where it enters the Missisippi and where Cairo IL is, farming methods, Minnesota and a couple of others.
You can be assured I know something about current farming methods.

Provide those later, more detailed articles that would show they can measure it with even more precision now. We are all waiting to learn what percentage of the nitrogen in the Gulf is from Iowa and exactly how this can and is measured. I do not feel this is nit picking. Do you remember my name - justcurious - well, that explains it -I'm just curious how this could actually work.
