Determine soil, hydrologic, and climatic data necessary to more accurately define and determine hydric soils (technical methodology and standards). Visit the National Technical Committee for Hydric Soils (NTCHS) web page for more information.

Hydric soil is soil which is permanently or seasonally saturated by water, resulting in anaerobic conditions, as found in wetlands. Most soils are aerobic.

2021年5月7日 · In wetlands, hydric soil supports the growth and regeneration of vegetation that has adapted to grow in saturated/inundated and low-oxygen conditions. Oftentimes the soil can be used to help identify a wetland type for purposes like wetland delineation.

State Soil Data Access (SDA) Hydric Soils List. An SDA-populated select list is used to pick a state and SSA which enables creation of a "Hydric Soils Report" based upon those selections. The data is not static; it hits Soil Data Access Live. To reset the table hit F5 on the keyboard.

Hydric soils facilitate & regulate the flow of water between groundwater systems & surface water systems. Biogeochemical cycling is dependent on the combination of aerobic & anaerobic conditions in hydric soils. The capacity of hydric soils to retain water & develop anaerobiosis promotes specific plant communities & unique wildlife habitats.

2024年11月10日 · Hydric soils are fundamental components of wetland ecosystems, playing a crucial role in supporting unique plant communities and providing essential ecological services. They are more than just wet dirt; they are a dynamic and complex environment shaped by the persistent presence of water.

Included in this publication are the hydric soil indicators approved by the NRCS and the National Technical Committee for Hydric Soils (NTCHS) for use in identifying, delineating, and verifying hydric soils in the field.

2024年3月31日 · Hydric soils aren’t simply wet soils; they are soils that have developed under conditions of frequent and prolonged saturation, ponding, or flooding, leading to a unique set of physical, chemical, and biological features. The key lies in the anaerobic environment created by this waterlogging.
