Established Series
Rev. GOW-JCD-TWN
01/2015


The Derinda series consists of moderately deep, moderately well drained soils on bedrock controlled topography of the driftless areas on rounded ridgetops, saddles, or structural benches. These soils formed in a thin layer of loess and in residuum from calcareous shales of Ordovician Age. Slopes range from 2 to 60 percent. Mean annual air temperature is about 8.3 degrees C (47 degrees F). Mean annual precipitation is about 890 millimeters (35 inches).

Dubuque--are in similar landscape positions and are underlain with limestone.
EleroyKeltnerMassbach, and Ridott--are in similar landscape positions, have a thicker loess mantle, and are deeper to a paralithic or lithic contact.
Schapville--are in similar landscape positions and have a mollic epipedon
Vanmeter--are in similar landscape positions and have a lighter surface color

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage class--moderately well drained; a saturated zone occurs within depths of 76 to 107 centimeters (2.5 to 3.5 feet) during March to June in normal years and is considered perched.
Saturated hydraulic conductivity is low or moderately low (0.01 to 1.41 micrometers per second). Permeability slow or very slow.
The potential for surface runoff is high to very high as related to slope.

USE AND VEGETATION: Most areas are small and land use is similar to adjoining areas. Where the soil is in large areas, it is cultivated or in pasture. The principal crops are hay, corn and small grains. The native vegetation is deciduous forest of oak, hickory, elm, basswood, and some ash.

LRRs--M; in the driftless areas of northwestern Illinois, southeastern Minnesota, northeast Iowa, and southwest Wisconsin
MLRAs--Central Wisconsin and Minnesota Thin Loess and Till (90B), Illinois and Iowa Deep Loess and Drift (108A and 108B), and Northern Mississippi Valley Loess Hills (105)
Central Mississippi valley wooden slopes - northern part (115C)
Extent--moderate
