The following are a subset of federal government agencies commonly involved in land and water management.
The U.S. Army Corps of Engineers St. Paul District office headquarters is located in downtown St. Paul, Minn. The agency has around 41 field sites in five states. The St. Paul District is one of six Corps districts that make up the Mississippi Valley Division, the headquarters of which is located in Vicksburg, Miss.

This module will cover both the five factors of formation and horizonation vs. simple processes. The module presentation will begin with a review of redox reactions and redoximorphic features. Reduction and concurrent oxidation (redox) are the dominant chemical processes taking place in wetland soils. There are abiological and biological driven redox reactions in wetland soils. The session focuses on reactions driven by microbial breakdown of organic matter in soils under saturated conditions that lead to unique anaerobic conditions that meet the hydric soil definition of USDA. These redox reactions lead to mobilization of soluble Fe and Mn (depletion zones and surfaces) and subsequent reoxidation (concentration zones and surfaces), collectively called redoximorphic features. Redox feature types are identified through images. Description of the features is briefly reviewed, in preparation for use as components of field indicators of hydric soils.

The target audience for these trainings are wetland field practitioners who need expertise in hydric soils and seek to understand how hydric soils are formed and how to recognize and interpret the information they provide when observed in the field.
