Hydric Soils Online Training Series
Module 1: The Five Factors of formation and Horizonation vs. Simple Processes
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.
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.
Module Learning Objectives
By taking part in this online training, participants should be able to:
- Define hydric soils
- Describe the five factors of soil formation
- Understand the differences between horizonation and simple processes
- Describe organic material additions, leaching, illuviation, organic matter and other processes
W. Lee Daniels the Thomas B. Hutcheson Professor of Environmental Soil Science at Virginia Tech in Blacksburg, Virginia. He received his Ph.D. in Soil Science from VPI & SU in 1985. Dr. Daniels areas of specialization include stabilization and restoration of disturbed lands including areas disturbed by mining, road building, waste disposal, urbanization and erosion. In particular, he has focused his research and consulting experience in wetland impact mitigation, mine reclamation, and soil-waste management systems. His teaching programs at Virginia Tech focus on soil geomorphology and landscape analysis with particular emphasis on the relationships among surficial geology, hydrology, soil patterns and long term landscape evolution processes. Major awards include the Reclamation Researcher of the Year by the American Society for Surface Mining and Reclamation (ASMR) in 1993, USEPA’s National Biosolids Utilization Research Award in 2000 and the Lifetime Achievement in Research Award by ASMR in 2012.
Link to Online Quiz
To complete this module, use the following link to access the module quiz on ClassMarker. Once you complete and submit the quiz, it will be automatically graded and you will receive your quiz score and the correct answers. Passing the quiz will also qualify participants to download a Certificate of Completion that the participant can submit themselves to accrediting organizations for continuing education credits.
To Take the Quiz and Receive a Certificates of Completion for this Module
Participants who both view the module presentation and complete the module quiz are eligible for an ASWM Certificate of Completion for 0.5 hours of training.
Using the ClassMarker online system, ASWM will ask you to certify that you completed viewing the entire hydric soils training module video presentation.
You will need to develop a username and password in ClassMarker. Once you click on the quiz link, you will be prompted again to provide your name and email address, which will be used to process your certificate.
To receive your certificate you must BOTH:
- Certify that you completed viewing of the video presentation. Answering “no” will result in no certificate being issued.
- Complete all 5 quiz questions, getting three or more of the questions correct. You will be provided three attempts to take the quiz for the module. If at the end of your third attempt you have not been able to get three or more correct, you will not be eligible to receive a certificate.
You will be prompted to download your Certificate of Participation from ClassMarker after you complete the quiz.
Once you download your certificate, you can then submit the certificate to the accrediting organization of your choice to potentially receive continuing education units/credits.
