LMV 1 h JC11GS <br />• • <br />part; about 1 percent pebbles by volume; strongly acid. <br />TYPE LOCATION: Sauk County, Wisconsin; about 1 1/2 miles north of Prairie du Sac; 90 feet south <br />from the center of the highway and 2,320 feet east from the center of sec. 26, T. 10 N., R. 6 E. <br />RANGE IN CHARACTERISTICS: Thickness of the loamy alluvium and the depth to sandy outwash <br />ranges from 20 to 40 inches. Thickness of the mollic epipedon ranges from 10 to 18 inches. Depth to <br />free carbonates typically is greater than 60 inches. Volume of gravel ranges from 0 to 15 percent in the <br />loamy alluvium. Volume of gravel averages from 0 to 35 percent in the sandy outwash but some <br />horizons may range up to 60 percent. Volume of cobbles range from 0 to 5 percent. <br />The Ap or A horizon has hue of 7.SYR or lOYR, value of 2 or 3, and chroma of 1 to 3. It is fine sandy <br />loam, sandy loam, loam, or silt loam. Reaction typically ranges from strongly acid to slightly acid, but <br />ranges to neutral where limed. <br />Some pedons have an AB or BA horizon with hue of 7. SYR or lOYR, value of 3 or 4, and chroma of 2 <br />or 3. It is loam, silt loam or sandy clay loam. Reaction typically ranges from strongly acid to slightly <br />acid, but ranges to neutral where limed. <br />The Bt horizon has hue of 7.SYR or l OYR, value of 4 or Sand chroma of 3 or 4. It is dominantly loam, <br />sandy clay loam, or clay loam but in some pedons there aze subhorizons of sandy loam, silt loam, or <br />clay loam. <br />Some pedons have a 2Bt horizon with hue of 7.SYR or l OYR hue, value of 4 or 5, and chroma of 3 to 4. <br />It is loamy sand, loamy coarse sand, sand or coarse sand, or the gravelly or very gravelly analogues of <br />these textures. Reaction ranges from strongly acid to slightly acid. <br />The 2BC horizon has color, texture, and reaction similar to the 2Bt horizon described above. <br />The 2C horizon has hue of 7. SYR or 1 OYR, value of 4 to 7, and chroma of 2 to 6. It is sand, coazse <br />sand, or loamy sand, or the gravelly or very gravelly analogs. Reaction ranges from strongly acid to <br />slightly acid. <br />COMPETING SERIES: These are the Lorenzo, Nineveh, Trempealeau, and Warsaw series. Lorenzo <br />soils have thinner Bola. Ninevah and Warsaw soils have gravelly clay loam lower Bt horizons that <br />tongue into the C horizon. Trempealeau soils have Bt horizons with redder hue. <br />GEOGRAPHIC SETTING: The Dakota soils are on outwash plains, stream terraces, and valley trains. <br />Slope gradients range from 0 to 18 percent. Frost free period ranges from 135 to 160 days. Elevation <br />ranges from 600 to 1000 feet. Mean annual temperature is 45 to 52 degrees F, and mean annual <br />precipitation is 28 to 33 inches. <br />GEOGRAPHICALLY ASSOCIATED SOILS: Dakota soils are mainly associated with Burkhardt, <br />Dickinson, Lawler, Pillot, and Sparta soils. Burkhardt soils aze in nearby areas to Dakota soils where the <br />loamy mantle is thinner. Nearby in sandier areas are the Dickinson and Sparta soils. In lower lying or <br />somewhat wetter areas are the somewhat poorly Lawler soils which form a drainage sequence with the <br />Dakota soils. In some places, where the upper mantle is siltier, the Pillot soils are nearby. <br />DRAINAGE AND PERMEABILITY: Well drained. Runoff is slow or medium.
