Note: A copy of relevant portions of
Soil Taxonomy, Agriculture Handbook No. 436 may be inspected
at the central offices of the Department of Agriculture, Trade and Consumer
Protection and the Legislative Reference Bureau. This volume is also commonly
available in USDA soil conservation service offices throughout the

The USDA soil conservation service has prepared soil
surveys for most Wisconsin counties, which can be found at the following web
address: http://websoilsurvey.nrcs.usda.gov/app/.
Atrazine users may refer to these surveys to determine the surface soil texture
in areas where they wish to apply atrazine. Atrazine users may also use
reliable sampling and testing methods to determine soil texture.
(23) "Surface soil" means the soil
ordinarily moved in tillage, or its equivalent in uncultivated soil, ranging in
depth from 4 to 10 inches.
