Hydric Soils | Natural Resources Conservation Service
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 - Wikipedia
Hydric soil is soil which is permanently or seasonally saturated by water, resulting in anaerobic conditions, as found in wetlands. Most soils are aerobic.
NRCS Hydric Soils List - Natural Resources Conservation Service
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.
Wetland Word: Hydric Soil | U.S. Geological Survey - USGS.gov
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.
Wetland and hydric soils | U.S. Geological Survey - USGS.gov
2020年9月3日 · Soil and the inherent biogeochemical processes in wetlands contrast starkly with those in upland forests and rangelands. The differences stem from extended periods of anoxia, or the lack of oxygen in the soil, that characterize wetland soils; in …
Hydric Soil - an overview | ScienceDirect Topics
A hydric soil is a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part of the soil. In organic wetland soils, a thick organic layer develops over time where microbial decomposition is severely slowed or remains incomplete under waterlogged conditions.
The NTCHS defines a hydric soil as a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). Most hydric soils exhibit characteristic morphologies that …
