COMPETING SERIES: This is the
Auburndale series.
Auburndale--have a sand content of 40 to 70 percent in the lower third of the series control section
GEOGRAPHIC SETTING:
Parent material--silty lacustrine deposits
Landform--glacial lake basins and stream terraces
Slope--0 to 2 percent

Mean annual air temperature--3 to 8 degrees C
Mean annual precipitation--660 to 865 millimeters
Frost-free period--110 to 180 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Campia,
Comstock, and
Crystal Lake soils.
Campia--are on higher landscape positions and do not have a frequently saturated zone within a depth of 1.8 meters during the wettest periods of years when precipitation is within one standard deviation of 30 year mean of annual precipitation
Comstock--are on slightly higher landscape positions and have a frequently saturated zone between depths of 0.3 and 0.75 meter during the wettest periods of years when precipitation is within one standard deviation of 30 year mean of annual precipitation
Crystal Lake--are on higher landscape positions and have a frequently saturated zone between depths of 0.75 and 1.0 meter during the wettest periods of years when precipitation is within one standard deviation of 30 year mean of annual precipitation
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage class--poorly drained--these soils are frequently saturated from the surface of the soil to a depth of 0.3 meter during the wettest periods of years when precipitation is within one standard deviation of 30 year mean of annual precipitation, this saturation is considered both perched and apparent
Saturated hydraulic conductivity--4.00 to 42.00 micrometers per second in the upper sediments and 1.00 to 4.00 micrometers per second in the underlying stratified sediments
Flooding--not flooded to rarely flooded for brief duration
Ponding--frequently ponded to a depth of 0.15 meter for long duration during the wettest periods of years when precipitation is within one standard deviation of 30 year mean of annual precipitation
USE AND VEGETATION:
Most areas are pastured or managed for hay production. Drained areas are cultivated. The principal crops are corn, small grain, and hay. The native vegetation is sedges and grasses with scattered American elm, black ash, aspen, and willows.
