Hydric Soils Online Training Series
Module 2: Soil Color and Texture
This module focuses on two physical soil properties --- texture and structure. Soil texture describes the relative proportions of sand, silt, and clay in a mineral soil. In soils where organic matter contents are high (such as hydric soils) organic textural classes or modifiers may be used to describe the soil texture instead. Soil structure describes the naturally occurring arrangement of soil particles into peds or aggregates. The combination of soil texture and structure influences how water is stored and moves through the soil, as well as other soil processes. This module covers how these properties are characterized, as well as how they influence hydric soil processes.
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:
- Describe the relative proportions of sand, silt, and clay in a mineral soil.
- Understand that soil structure describes the naturally occurring arrangement of soil particles into peds or aggregates.
- Understand how the combination of soil texture and structure influences how water is stored and moves through the soil, as well as other soil processes.
- Understand how to use organic textural classes or modifiers to describe soil texture in soils where organic matter contents are high (such as hydric soils) and characterize these properties
- Understand how these properties influence hydric soil processes.
Annie Rossi is a soil scientist currently working within EPA’s Wetlands Division at EPA Headquarters in Washington, D.C., under an appointment to the Oak Ridge Institute of Science and Education (ORISE) Research Participation Program. She provides support to the National Wetland Condition Assessment, particularly in areas of hydric soils, field protocol development and training, and data analysis. She is also researching soil indicators that could be used to monitor and assess wetland condition and stress as part of the National Wetland Condition Assessment. Annie received her doctorate in Environmental Science and Technology from the University of Maryland. Her dissertation research focused on soil processes in wetlands on Mid-Atlantic barrier islands, including the development of Hydric Soil Field Indicators for use in the region
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.
