Introduction
~~~~~~~~~~~~
This example is based on first selecting a specific set of soils (e.g.,
hydrologic group A, supporting potatoes, texture class Sandy Loam
or Sand in all layers) then determining where those soils occur.  The area
that contains the largest amount of these soils is then selected as the
geographic area to use.  The pesticide used is Carbofuran and the crop is
potatoes.  A standard run comparing 5 scenarios is performed.
