COMPETING SERIES: These are the Abscota, Platteriver (T), and Solo series. Abscota soils have an irregular decrease in organic carbon with depth. Platteriver soils average less than 50 percent fine sand in the particle-size control section. Solo soils occur outside of LRRs L and M in areas that receive more than 42 inches of mean annual precipitation.
GEOGRAPHIC SETTING: The Denham soils formed in sandy eolian deposits on outwash plains, glacial lake plains, and moraines. Slope gradients range from 0 to 5 percent. Mean annual temperature ranges from 48 to 53 degrees F., mean annual precipitation ranges from 30 to 42 inches, frost-free period ranges from 130 to 180 days, and elevation ranges from 580 to 1530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are principally the Brems, Granby, Maumee, Morocco, Newton, and Oakville soils. The moderately well drained Brems and somewhat poorly drained Morocco soils are on slightly lower positions on the landform. The poorly drained or very poorly drained Granby and Maumee soils and the very poorly drained Newton soils are in depressions. Oakville soils are excessively drained and are on higher positions.
DRAINAGE AND PERMEABILITY: Moderately well drained. The potential for surface runoff is negligible. Permeability is rapid or very rapid. The depth to the top of a seasonal high water table ranges from 3 to 6 feet below the surface from December to April in normal years.
USE AND VEGETATION: Most areas of Denham soils are used for raising corn, soybeans, and wheat. Some small areas are in hay, pasture, or woodland. Native vegetation is deciduous forest.
DISTRIBUTION AND EXTENT: MLRA 98 and 111 in northern Indiana. The soils are currently of small extent, but acreage is expected to increase as more surveys are updated.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
