PEI SOIL SURVEY 1970-1978

MAP UNIT NUMBER

 Each delineation on the soil map is identified by letter symbol: two letters for the soil name and one letter for each phase described.  Map units are listed in alphabetical order for ease of reference, except for the miscellaneous land types grouped at the end.

Example:

1. Soil series:  Alberry

2.  Soil Phase1: Stony surface phase                  

1    2 3   4 5     6

Al:AC/CC-CH 3.  Soil Phase 2: Consolidated bedrock

4.  Slope phase: 2 to 5%

5.  Dominant surface texture: Sandy loam

6.  Second Series: Charlottetown

The first two letters in the numerator of the map symbol refer to the soil series.

The third or fourth letter in the numerator refers to soil modifier1 or soil modifier2 as follows:

A – Stony surface phase

B – Moderately well drained phase (Class 3 drainage)

C – Consolidated bedrock phase (50 to 100 cm depth)

D – *Unconsolidated bedrock phase (50 to 100 cm depth)

E – Cobbly or stony subsoil phase

F – Peaty surface phase

G – Ortstein phase

I – Coarse or moderately coarse texture (20 to 50 cm depth)

J – Medium to moderately fine texture (20 to 50 cm depth)

K – Complex, undifferentiated

The first letter in the denominator refers to the slope phase as follows:

B – 0 – 2% slope

C – 2 – 5 % slope

D – 5 – 9% slope

E – 9 – 15% slope

F – 15 – 30% slope

G – more than 30% slope

I – 5 – 15% slope (DE complex)

J – 9 – 30% slope (EF complex)

The second letter in the denominator refers to the dominant surface texture as follows:

A – Sand or coarser

B – Loamy sand or gravelly loamy sand

C – Sandy loam (<8% clay)

D – Fine sandy loam or very fine sandy loam

E – Loam or silt loam

F – Sandy clay loam or clay loam

If a second soil is shown for any delineation it is placed as the last two letters in the denominator of the symbol.

SOIL CLASS

The classes indicate the degree of limitation imposed by the soil in its use for mechanized agriculture. The subclasses indicate the kinds of limitations that individually or in combination with others, are affecting agricultural land use.

1. No significant limitations
2. Moderate limitations, moderate conservation practices required
3. Moderately severe limitations, range of crops restricted or special conservation practices required.
4. Severe limitations
5. Forage crops improvement practices feasible
6. Forage crops improvement practices not feasible
7. No capability for arable culture or permanent pasture
99. No classification assigned, polygon is a miscellaneous landtype

DRAINAGE GROUP

This is a generalized classification of soil drainage based on soil types, soil texture and phases.

Imperfect	Imperfectly drained
Organic	Soil has an organic layer on surface
Poor	Poorly drained
Rapid	Rapidly drained
Shallow_B	Soil profile to bedrock is less that 50cm
Well	Well drained
Well_col	Well drained and soil has a coarse loamy texture
Well_med	Well drained and soil has a medium texture
Well_shall	Well drained and soil has a shallow profile

DRAINAGE TYPE

Very rapidly drained
Water is removed from the soil very rapidly in relation to supply. Excess water flows downward very rapidly if underlying material is pervious. There may be very rapid subsurface flow during heavy rainfall provided there is a steep gradient. Soils have very low available water storage capacity (usually less than 2.5 cm) within the control section and are usually coarse textured, or shallow, or both. Water source is precipitation.

Rapidly drained
Water is removed from the soil rapidly in relation to supply. Excess water flows downward if underlying material is pervious. Subsurface flow may occur on steep gradients during heavy rainfall. Soils have low available water storage capacity (2.5-4 cm) within the control section, and are usually coarse textured, or shallow, or both. Water source is precipitation.

Rapidly drained

Soil moisture content seldom exceeds field capacity in any horizon except immediately after water additions.

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.

Moderately well drained
Water is removed from the soil somewhat slowly in relation to supply. Excess water is removed somewhat slowly due to low perviousness, shallow water table, lack of gradient, or some combination of these. Soils have intermediate to high water storage capacity (5-6 cm) within the control section and are usually medium to fined textured. Precipitation is the dominant water source in medium to fine textured soils; precipitation and significant additions by subsurface flow are necessary in coarse textured soils.

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.

Poorly drained
Water is removed so slowly in relation to supply that the soil remains wet for a comparatively large part of the time the soil is not frozen. Excess water is evident in the soil for a large part of the time. Subsurface flow or groundwater flow, or both, in addition to precipitation are the main water sources; there may also be a perched water table, with precipitation exceeding evapotranspiration. Soils have a wide range in available water storage capacity, texture, and depth, and are gleyed subgroups, Gleysols, and Organic soils.

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.

Organic

Soil has an organic classification.

Other

Polygon has a non-soil (landtype) classification

Water

Polygon is an open water area
