Very good report.  Thanks for sharing.  

They utilize the term, "saturated" quite a bit.  Wish there was a way to quantify that term. 

When is a soil saturated, and when isn't it?  What about levels of saturation.  Would assume light saturation has a certain measure of nitrogen loss, and heavy saturation has a larger measure of nitrogen loss.  How do we differentiate that?

I guess it all goes to show..... "Farming isn't an exact science."  Ain't that the truth!
