Description of soil MBMNVu~~~~N (Martinville)

General Characteristics
Classification R.HG

Rego Humic Gleysol

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 Always

The water table is always present in the soil.

Root restrictions First layer

The growth of plant roots is restricted by the first (uppermost) layer.

Type of root restricting layer Salinity

Salinity (conductivity > 4 dS/m)

Drainage Very poorly drained

Water is removed from the soil so slowly that the water table remains at or on the surface for the greater part of the time the soil is not frozen. Excess water is present in the soil for the greater part of the time. Groundwater flow and subsurface flow are the major water sources. Precipitation is less important except where there is a perched water table with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are either Gleysolic or Organic.

Parent Materials
Mode of Deposition Texture Chemical properties
Uppermost Lacustrine

Sediment, generally consisting of either stratified fine sand, silt, and clay deposited on the lake bed, or moderately-well sorted, stratified sand and coarse materials that consist of near lake shore or beach deposits. These materials have either settled from suspension in bodies of standing fresh water or accumulated at their margins through wave action.

Medium

Medium (USDA Texture Classes: VFSL,L,SIL,SI,GL,GSIL).

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)

Below Lacustrine

Sediment, generally consisting of either stratified fine sand, silt, and clay deposited on the lake bed, or moderately-well sorted, stratified sand and coarse materials that consist of near lake shore or beach deposits. These materials have either settled from suspension in bodies of standing fresh water or accumulated at their margins through wave action.

Coarse

Coarse (USDA Texture Classes: FS,LCS,LS,LFS,GLS,CBLS).

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
