CLARION
TYPIC HAPLUDOLL
Location: Freeborn county Soil Association Map Unit D8
The Clarion series consists of well-drained soils that are moderately permeable. These soils formed in friable, glacial till. They are on knolls, hilltops, and side slopes of upland till plains. Slopes range from 2 to 25 percent. The native vegetation was tall prairie grass.
Permeability is moderate. Surface runoff is medium, and available water capacity is high. Reaction of surface layer is neutral. The content of organic matter is high, and natural fertility is high.
Most areas of this soil are used for crops. This soil has good potential for crops, pasture, and windbreaks. It has fair potential for building site development and sanitary facilities.
This soil is well suited to cropping if it is adequately fertilized, if all crop residue is returned to the surface, and if conservation measures are used to control erosion. Because the slopes are short and complex, minimum tillage is more effective in controlling erosion than contouring and terracing.
This soil is well suited to trees and shrubs used for windbreaks. Preparing the site during the fall before planting controls weeds and improves the seedbed so that is can be worked in early spring without causing clodding. Weeds and grasses can be controlled in newly established windbreaks by shallow cultivation or use of approved herbicides.
This soil has fair potential for building site development and most sanitary facilities because it is limited primarily by slope. Roadfill of greater strength is needed if roads are to function properly. Slope is a limitation for septic tank absorption fields but can be overcome by proper design and installation.
This soil is in capability subclass IIe.
