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.

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.
