Description of soil MBMRK~~~~~N (Morin Lake)

Terric Mesic Fibrisol

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

This material was not classified due to an absence of information or an unusual situation, such as rockland or an extremely shallow soil.

The water table is always present in the soil.

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

Not Applicable

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.

These deposits consist of sphagnum or forest peat formed in an ombrotrophic environment caused by the slightly elevated nature of the bog. They tend to be disassociated from nutrient-rich ground water or surrounding mineral soils.

Fibric

pH < 5.6

These deposits consist of sedge peat derived primarily from sedges with inclusions of partially decayed stems of shrubs formed in a eutrophic environment due to the close association of the material with mineral-rich waters.

Mesic

pH 5.6 - 7.4

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.

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