About these numbers
The main number is the county's estimated farm glyphosate use for the year divided by all of its land, water left out. A county with a little farmland can use a lot per square mile of cropland and still have far less in total than a county with more farmland, so the whole-county number is the one the map colors, ranks and compares.
These are county estimates, not records. They don't show which fields were sprayed or how much any one field got.
USGS makes a low and a high estimate, which fill in use that farms didn't report in different ways.
Per square mile of cropland is the same total spread evenly over the county's cropland only, so it's higher than the whole-county number wherever only part of Cheyenne County, Colorado is farmland.
Numbers are in pounds per square mile. The source gives kilograms per square kilometer, and 1 kg per km² is about 5.7 pounds per square mile.
