What type of soils would you expect in Hydrologic Soil Group C?

Hydrologic Soil Group C includes soils that have moderate infiltration rates and are typically comprised of moderately fine to fine-textured materials. These soils can retain moisture but still allow for some drainage, making them less permeable than soils in Group A (well-drained) and Group B (moderately well-drained). The texture of Group C soils usually includes materials like loams and silty loams, which can support plant growth while also contributing to areas of potential runoff during heavy rainfall events.

The other options highlight characteristics that do not accurately reflect Group C. Deep, well-drained soils would typically fall into Group A, as they have high infiltration rates. Clays with high swelling potential are better categorized under Group D due to their poor drainage capabilities during wet conditions. Finally, excessively drained sands also do not align with Group C, as they are more representative of Group A, known for their rapid drainage and high infiltration capacity.
