The aquic (L. aqua, water) moisture regime signifies a reducing regime in a soil that is virtually free of dissolved oxygen because it is saturated by ground water or by water of the capillary fringe. Some soils at times are saturated with water while dissolved oxygen is present, either because the water is moving or because the environment is ...
USDA soil taxonomy - Wikipedia
Aquic: Soil is saturated with water and virtually free of gaseous oxygen for sufficient periods of time, such that there is evidence of poor aeration (gleying and mottling); common in wetlands. Udic: Soil moisture is sufficiently high year-round in most years to meet plant requirement; common in humid regions. Ustic

Ustic - Wikipedia
Ustic is a class of soil moisture regime. It is one of a range of different soil moisture regimes, such as: aquic moisture regime, aridic moisture regime, udic moisture regime and xeric moisture regime. The ustic moisture regime is intermediate between the …
Aquic conditions for Soil Taxonomy: concepts, soil morphology …
1993年1月1日 · Aquic moisture regimes have been redefined in Soil Taxonomy and are now called aquic conditions. The new system uses micromorphological concepts to define macroscopic indicators that show that a soil has been saturated and reduced.
Redoximorphic Features for Identifying Aquic Conditions
2015年8月12日 · This bulletin describes requirements for aquic conditions; shows how to identify and describe redoximorphic features needed to define aquic conditions; an….
Aquic conditions.—A diagnostic soil characteristic of mineral or organic soils that indicates the presence of continuous or periodic saturation and reduction in one or more layers, which leads to biogeochemical reduction of Mn and Fe. The criteria include saturation, reduction, and (for mineral soils) the presence of . .
Overview of Aquic Conditions and Hydric Soils - ACSESS
1997年1月1日 · Major differences between hydric soils and soils with aquic conditions are the depths at which saturation and reduction must occur, the timing of the saturation and reduction, and the principle user groups.
Soil Data Explorer | California Soil Resource Lab - UC Davis
Aggregate lab data for the AQUIC XEROFLUVENTS soil series. This aggregation is based on all pedons with a current taxon name of AQUIC XEROFLUVENTS, and applied along 1-cm thick depth slices. Solid lines are the slice-wise median, bounded on either side by the interval defined by the slice-wise 5th and 95th percentiles.
Moisture regimes - SpringerLink
2016年1月1日 · aquic: A mostly reducing soil moisture regime nearly free of dissolved oxygen due to saturation by groundwater or its capillary fringe and occurring at periods when the soil temperature at 50 cm below the surface is >5 °C.
