ATCP 30.30 NoteThe 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. ATCP 30.30(23)(23) “Surface soil” means the soil ordinarily moved in tillage, or its equivalent in uncultivated soil, ranging in depth from 4 to 10 inches. ATCP 30.30 HistoryHistory: Cr.
