Nutrient Criteria Slide Show            Slide 20

The following series of graphs look at nutrients in relation to the percentage of land cultivated in row crop.  Each graph is arranged in the same way...

The left (Y1) axis provides the concentration of the nutrient being graphed.  


The right (Y2) axis measures land use %.  


The bottom (X) axis shows sampling sites arranged, from left to right, in order of lowest to highest % of floodplain land in row crop.  Where sites have no row crop in the floodplain, they are ordered, again left to right, based on the % of land in agriculture.  


Finally, each graph shows the USEPA proposed nutrient standard for the nutrient being graphed.
