Description of soil ABTBR~~~~~N (TWIN BRIDGES)

General Characteristics
Classification GL.HR

Gleyed Humic Regosol

Profile Native soil profile

The soil is in native condition (undisturbed by agriculture).

Kind of material Mineral

The soil material is primarily composed of mineral particles.

Water table Unspecified period

The water table is present in the soil during an unspecified period.

Root restrictions No root restricting layer

The growth of plant roots is not restricted by any soil layer.

Type of root restricting layer n/a

Not Applicable

Drainage Imperfectly drained

Water is removed from the soil sufficiently slowly in relation to supply, to keep the soil wet for a significant part of the growing season. Excess water moves slowly downward if precipitation is the major supply. If subsurface water or groundwater, or both, is the main source, the flow rate may vary but the soil remains wet for a significant part of the growing season. Precipitation is the main source if available water storage capacity is high; contribution by subsurface flow or groundwater flow, or both, increases as available water storage capacity decreases. Soils have a wide range in available water supply, texture, and depth, and are gleyed phases of well drained subgroups.

Parent Materials
Mode of Deposition Texture Chemical properties

These sediments generally consist of gravel and sand with a minor fraction of silt and rarely of clay. The gravels are typically rounded and contain interstitial sand.

Moderately Coarse

Moderately Coarse (USDA Texture Classes: VFS,LVFS,CSL,SL,FSL,GSL,CBSL,GFSL).

Extremely Calcareous

> 40 CaCO3 equivalent (%)
