Like anything new, the easiest way to proceed is one step at a time. In this four hour self-directed course we'll walk you through the foundations of soil knowledge. We'll provide some short quizzes to help you gauge if you're ready to move on to the next topic. In this course we discuss: Soil parent materials Soil formation Soil texture and using the textural triangle The types of soil structure and how structure impacts other soil properties The basics of soil color and how to use a color book Redoximorphic features and the processes that form them Understanding some of the basics of soil classification and taxonomy and how they relate to the soil survey Understanding saturated versus unsaturated flow in soils Soil pH and basic soil chemistry principles - [Advanced Hydric Soils - Online](https://www.soilhub.com/product/advanced-hydric-soils-online/) - Classroom Component: Online and on demand Field Component: There is no field component associated with the online only version of this class The advent of the Hydric Soil Indicators into three-parameter wetland delineations has raised the bar on understanding the role of soils in wetland determinations. However, like any advance in scientific application, the divide between intent and application can be wide as field practitioners struggle to comprehend the intention of the many-nuanced and often-updated hydric soil indicator definitions. In this course, students will learn advanced soil science concepts from professional soil scientists to bridge the knowledge gap between reading what an indicator says and applying it in the field. Students will complete 6 hours of online classroom study through our Soil Hub learning modules. These modules can be completed all at once or the student can stop and start at their own pace with the option to save their progress and return later to complete each lesson. Students will advance their technical foundation with in-depth study on the science behind the indicators. At the conclusion of the course, students can expect to have an advanced understanding of: Soil horizon nomenclature including master horizons and subdivisions Soil horizon boundary descriptions Describing coarse fragments, soil structure, and other soil physical properties Redoximorphic feature chemistry Methods of determining soil parent material Understanding and describing landforms Identifying and describing redoximorphic features - [Stormwater Infiltration Boot Camp Online](https://www.soilhub.com/product/stormwater-infiltration-boot-camp-online/) - Classroom Component: Online and on demand Field Component: There is no field component associated with the online only version of this class In this class we take a close look at key areas to successful stormwater infiltration siting, testing, design, and construction. When working with a system that relies heavily on soil to provide an ecosystem service, we must have a firm understanding of the science behind the processes. Successful stormwater management depends on using the right soil, using an appropriate design infiltration rate, and fulfilling the assumptions behind the design by taking the right steps during construction. In the online classroom material, we’ll begin by studying how the use of infiltration to help renovate stormwater is predicated on understanding the physics behind how water behaves at the soil-water interface as well as within the soil matrix. A firm understanding of these relationships will assist in proper site selection and design parameters. Then we’ll look at the limitations that exist in some soils that inhibit the proper renovation of stormwater. Additionally, with a firm understanding of soil properties that govern renovation success, we go over infiltration testing techniques and best practices. By identifying soil limitations and learning to test the correct soil horizons using sound protocols, more accurate data can be generated to provide a better decision framework for designers. Finally, no matter how much science we know, no matter how many infiltration tests we conduct, if care isn’t taking during construction, none of it matters. We discuss best practices to reduce compaction, the importance of organic matter, and planning construction with infiltration in mind. Students will complete three hours of online classroom study through our Soil Hub learning modules. These modules can be completed all at once or the student can stop and start at their own pace with the option to save their progress and return later to complete each lesson. - [Fundamental Hydric Soils - Online](https://www.soilhub.com/product/fundamental-hydric-soils-online/) - Classroom Component: Online and on demand Field Component: There is no field component associated with the online only version of this class *** Approved for 0.4 Certification Renewal Points through the Society of Wetland Scientists *** This Course has been pre-approved by the Society of Wetland Scientists Professional Certification Program (SWSPCP) as meeting standards for content and instruction to receive credits and/or points toward SWSPCP Professional Certification or SWSPCP Professional Certification Renewal. The advent of the Hydric Soil Indicators into three-parameter wetland delineations has raised the bar on understanding the role of soils in wetland determinations.

When working with a system that relies heavily on soil to provide an ecosystem service, we must have a firm understanding of the science behind the processes. Successful stormwater management depends on using the right soil, - [Soil Physical Properties](https://www.soilhub.com/courses/soil-physical-properties/) - This course goes over the different physical properties soil scientists use to describe soils. Emphasis will be on soil color, texture, and structure. We'll also introduce the concept of redoximorphic features and describe their role in determining saturation and reduction in soils. This course will take you approximately one hour to complete. You may pause - [Soils and Their Formation](https://www.soilhub.com/courses/soils-and-their-formation/) - This course provides a general overview of soils and soil formation. Emphasis is on understanding the 5 Soil Forming Factors, soil parent materials, and processes involved in soil formation and development. This course will take you approximately 30 minutes to complete. You may pause your progress at anytime and return to the course and resume - [Describing and Sampling Soils](https://www.soilhub.com/courses/describing-and-sampling-soils/) - This course goes over the basics of soil profile descriptions, what you might see in published soil data, and basics of soil taxonomy. You'll be exposed to the web soil survey and official soil series descriptions. This course will take you approximately one hour to complete.
