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 state. Microsoft Windows NT 6.1.7601 Service Pack 1 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. Microsoft Windows NT 6.1.7601 Service Pack 1
