Description of soil ONGVI~~~~~A (GRENVILLE)

General Characteristics
Classification O.MB

Orthic Melanic Brunisol

Profile Agricultural soil profile

The soil has been disturbed 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 Well drained

Water is removed from the soil readily but not rapidly. Excess water flows downward readily into underlying pervious material or laterally as subsurface flow. Soils have intermediate available water storage capacity (4-5 cm) within the control section, and are generally intermediate in texture and depth. Water source is precipitation. On slopes subsurface flow may occur for short durations, but additions are equaled by losses.

Parent Materials
Mode of Deposition Texture Chemical properties
Till (Morainal)

Morainal material (till) deposited by glacial ice: a mixture of boulders, sand, silt, and clay.

Medium

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

Moderately / Very Strongly Calcareous

6 - 40 CaCO3 equivalent (%)
