Yes, just as I thought. No answer. Merely more convaluted logic about rivers. The Mississippi, of course, runs along the border of Wisconsin, so you are assuming that there's no runoff from Wisconsin in those hundreds of miles?
There is runoff from Wisconsin but not into Iowa.
In the interest of accuracy, the common border between Iowa and Wisconsin is not "hundreds of miles" but is less the one hundred miles. More like 90.
Do other rivers from other states run into Iowa?
Yes.
Would the eleven year old care to share with you how to measure nitrogen in the gulf and determine its origin at the same time?
The eleven year old knows that what you ask is not possible. But she does understand how it is possible to determine how much nitrogen from Iowa flows into the Gulf.
She also wonders why it is so difficult for others.
So many questions that you won't answer.
My goodness, how foolish you appear when you try to cover your stupidity with false reasoning and outright lies.
It's not my stupidity nor false reasoning that's the problem here. And I've told no outright lies.
I've explained multiple times in somewhat different ways how this can be done but you and BS and perhaps some others insist on presenting a method that can't be done and then accusing me of not understanding it.
