Nitrate Leaching Class Ranges

[ Update this Record ]

Abstract: This is a statewide Arc/Info data set of nitrate leaching class ranges for
soils in Illinois. It was generated to aid in determining aquifer sensitivity
to nitrate leaching in Illinois. The source map was digitized at 1:250,000, but
was developed from source data mapped at 1:15,000. The publication of this map
was at 1:500,000. Nominal scale is 1:250,000.

Purpose: Two statewide data sets were identified as containing information that would be
useful for producing aquifer sensitivity maps: a soil association map (and
database) and a map of geologic materials to a depth of 50 feet (Stack-unit
map). The soil association map and database were used in an interpretive
mapping model that generated a map of nitrate leaching classes by ... View entire text
