Hello Jong,
I’ve attached a spreadsheet with the data for the fertilizer rates for all the counties in the Mississippi River Basin. This is the data that was sent to me by Mark David. I have also attached the paper he published based on this data. The GIS layer should look like figure 4 in the attached paper. You can use other color schemes if you wish. We could also divide up the categories differently if needed. I won’t be able to participate on the Thursday meeting this week, but please let me know if you have any questions. I am on the road through Thursday but I can respond in the evenings.
John
