SOIL FORMiNG FACTORS

Timc, parcnt matcrial, climatc, tOpOgrdphy (drainage), vcgctation, and organiqms arc impor- tant in soi1 dcvclopmcnt. Givcn the morc or lcss uniform timc framc of soi1 dcvclopmcnt and clima- tic conditions wiihin the watcrshcd, thc major factors accounting for soi1 dificrcnccs arc: parcnt matcrial origin; topographic position and rclicf as il aiïwts drainagc; vcgctation, forcst vcrsus agric- ulture; and organisms - csp ia l ly man. Land usc is a particularly important soi1 iorming factor bccausc it is rcsponsiblc for changcs of largc magnitudc in both surfacc soi1 dcplction duc to crosion, or its incrcmcnt duc to scdimcnt deposition (ovcrwash).

Gcology

Acwrding to the Gcological Map o f Ncw Brunswick at the 1:50(1 O scalc (Pottcr ct al., 1x58) the wdtcrshcd is undcrlain by Ordovician and/or Silurian (Maiapuiia Group) calcarcous and argillaccous scclimentary rocks (shalc, slatc, limc- stonc) with somc intcrbcddcd volcanic rocks.

Parent material

During the last Glacial Icc Agc, thc study arca was covcrod with a lobc of thc Wisconsin icc shcet. Glacier retrcat consistai of a scrics oï rctrcab and rcadvanccs rcsulling in thc deposition of scvcral laycrs of dnfL Bcing at the cnd of thc glacicr icc shcct, an abundancc o f glaciofluvial dcposits a h accompanicd ihc usual morainal till deposils.

portion, however, topography is more strongly

rolling with slopes of 5-16%. In this same area

some (<5% of cleared land) man-made terraces

with 3-6% slopes arc also present

Climate

The watershed is situated in a moderately

cool boreal climate with a humid to perhumid soil

moisture regime. Mean monthly temperatures,

rainfall, snowfall, and growing degree days (Enviro¬

nment Canada, 1982a) are shown in Table 1.

The frost free period extends over 120 days

on average (Environment Canada, 1982b).

Vegetation

In the Black Brook watershed, forest

constitutes less than one quarter of the total land

area (Figure 3). It is represented by one major

forest complex at the source of the Black Brook

and scattered patches of woods along the rest of

the stream course. In this riparian forest the

dominant tree species include eastern cedar, black,

while, and red spruce; balsam fir; white and

blackberry; raspberry; sphagnum; mountain-fern;

Schrebcr's, plume, broom, and mnium mosses;

shining clubmoss; and bracken, wood, and ostrich

ferns.

Land use

Agricultural land constitutes approxi¬

mately 1050 ha, the rest of the watershed being

forested. The major crop is potatoes in rotation

with grains, peas, and hay for forage. Some of the

land is kept under pasture.

A common field observation in cultivated

lands was to find that the Bf horizon originally

present in native soils had vanished or was severely

depleted (<5 cm thick) and average depth to the

parent material decreased. This implies that some

of the original soil material at the surface was

removed by erosion. There were also sites in

which the Ap, the uppermost soil horizon, was

more than 50% thicker than average, for example,

being 40 cm thick, whereas the typical plow layer

is only 25 cm thick. These sites illustrate soil over-

wash (rcdcposition of eroded sediment). Over

48% (511 ha) and 8% (90 ha) of cleared land were

classified as eroded and ovcrwash soils, respective¬

ly. At the same tune, there were sites with similar

soils and comparable topographic features that

displayed no such soil modifications. This vari¬

ation is attributed to different field management

It stresses the importance of land use as one of the

dominant soil forming factors in modifying profile

characteristics.

SURVEYING METHODS

The watershed area was mapped at the

scale of 1:10 000. Within the watershed, 254 ha

had previously been surveyed at the same scale as

part of the on-fann soil survey program (MacMil-

lan, no date). This area was not re-surveyed but

instead the on-fann data were incorporated into

the final map.

On average one soil inspection was made

for every 2 ha of agricultural land and for every 9

ha of forested land. Each inspection consisted of

observing the soil to a depth required for classi¬

fication, considering a control section of 1 m. The

following soil profile properties were recorded: soil

parent material, drainage, depth to constricting or

contrasting layer, depth to bedrock, textures of the

soil surface and of the parent material, soil phases,

and horizon sequence. Slope, stonincss, and

rockincss were also noted (Agriculture Canada

Expert Committee on Soil Survey, 1983). This

information allowed for identification of the soil at

the association level. Inspection sites were chosen

using a combination of free mapping and the

transcct approach (Agriculture Canada Expert

Committee on Soil Survey, 1981). Coloured 1:12

500 scaled aerial photographs were used for site

selection and location. Line base maps at scale 1:4

800 were also available for some of the survey

area.

Once all field inspections were done, the

aerial photographs were used to finalize soil

polygon boundaries. The mapping unit identifies

the soil that is dominant in a delineated polygon

and is described at the association level. For this

report an association is considered as the equival¬

ent of a soil catena, consisting of soils that have

developed on the same parent material but differ

in drainage characteristics because of topographic

position. A maximum of 15% inclusions of dif¬

ferent soil types was allowed. Some units of

strongly contrasting conditions or land use were

assigned land type designations (see list below in

SOIL CLASSIFICATION). The published map

symbol consists of the soil association, phase

(where present), drainage, and slope as based on

soil and site characteristics recorded in the field.

It has the following format:

Soil Association (Phase) Drainage f Slope

e.g. Ho(e)2/c

SOIL CLASSIFICATION

The soil associations found in the Black

Brook watershed are described in Table 2 and their

general locations are shown in Figure 4. Six

mineral soil associations and one organic soil

association were identified during the mapping

exercise:

Mineral - Grand Falls

Holmcsvillc

Interval

Muniac

Sicgas

Undine

Organic - St Qucntin.

Generalized characteristics of the associa¬

tions are provided in the following pages under

"MAPPING UNIT DESCRIPTION". These

descriptions combine information from Fahmy et

at (1986) and Langmaid et ai (1980 and 1976) as

well as reflect the particularities of the survey area

which were identified during the detailed field

investigations.

The following connolalivc land types were

also identified during the mapping process:

Farmyard

Lagoon

Sinkholc

St. Andrc (village of)

Stone Pile

Stream Valley

Water

Phases were used to identify map units in

which a significant component (>33%) of the

polygon varied from the central concept of the soil

association. The soil association phases that were

considered arc:

e - eroded (Bf<5cm),

o - overwash (Ap>1.5 limes average Ap

thickness),

s - shallow to bedrock (<5()cm), and

v - variable depth to bedrock (IQ-l(X)cm).

When eroded (c), lodgment till soils such

as Holmcsvillc and Sicgas have less available

friable surface soil material for root growth. Con¬

versely, overwash phases (o) where eroded sedi¬

ments have been rcdcpositcd, tend to have

increased available rooting zones. Overwash

materials, because of their relative fineness, may

enhance the water and nutrient retention capabil¬

ities of coarser tcxturcd soils, such as Grand Falls.

Units mapped as cither shallow to bedrock (s) or

variable depth to bedrock (v) are usually affected

by bedrock outcrop. However, most of these sites

arc at worst only slightly rocky, with 2-10% of the

unit's surface area being rock exposures. Units that

arc both eroded, and cither shallow or variable

depth to bedrock, arc most likely to have bedrock

outcrop, but still these lend to occupy less than

10% of the total unit area. It should be noted that

by definition, sites with less than 10 cm of

unconsolidalcd soil material over solid bedrock are

considered rock exposures.

Soil material of representative mapping

units was collected at the end of the soil survey.

These samples were chemically and physically

analyzed and the results of these analyses arc pres¬

ented in Appendix 1 along with morphological

descriptions of the soil profile.

In the reconnaissance mapping of Madaw-

aska (Langmaid et at, 1980) and Northern Victoria

(Langmaid et ai, 1976), soil series were designated

in the mapping unit and map symbol In this

report only soil association names are used. The

name of the soil association was taken from the

catena soil series that has the "best" natural drain¬

age. To maintain correlation with existing soil

names, this relationship between soil associations

and established soil series is provided in Table 3.

MAPPING UNIT DESCRIPTIONS

GRAND FALLS

Extent and distribution

The Grand Falls mapping units occur

along the Black Brook in the lower part of the

watershed. They cover 48.1 ha of agricultural land

and riparian forest.

Soil material, range in characteristics, and topog¬

raphy

Grand Falls arc deep, olive gray, strongly

to medium acid, gravel soils, very low in natural

fertility, which have developed on glaciofluvial

deposits of noncalcarcous slate, quarlyjtc, and

sandstone. They have a loose, rapidly permeable,

very gravelly loamy sand to loamy gravel parent

material and a friable to loose, moderately per¬

meable, gravelly sandy loam or possibly loamy sand

topsoil. Coarse fragments arc rounded gravels and

cobbles, usually exceeding 50% of the soil volume.

Surface sloniness is not a problem. Most units are

only slightly stony, with stones 10-30 m apart.

Grand Falls soils occupy well, moderately well, im¬

perfectly, and poorly drained sites.

Slopes range from 2 to 15% with sites

varying from horizontal or gently inclined terraces

to the steep sides of bnxik valleys.

Land use

These units form strips of land along the

edges of riparian forest. Hence, they arc cultivated

the same way as the rest of a field that may con¬

tain more agriculturally suitable soils. On the

other hand, since these units are located at the

bottom of hills that have been subjected to years of

up-and-down slope cultivation, they often serve as

eroded sediment sinks, thus, enhancing the inher¬

ently low fertility of the lopsoil. So, even though

these mapping units arc generally less suitable

because of low water holding capacity and low

fertility, potatoes, grains, and peas arc successfully

grown. The forested areas of Grand Falls soils arc

poorly drained, with sparsely growing trees of

eastern cedar, balsam fir, black spruce, speckled

alder, willow, and ground vegetation including

wood sorrel, bunchbcrry, goldthread, yellow clin-

lonia, twinflowcr, wood fern, mountain fcm and

Schrcbcr's mosses.

Differentiating from other units

The Grand Falls mapping units are readily

differentiated from soils which have developed on

compact lodgment till (Holmesville and Siegas)

and residual material (Undine), however, they may

be confused with the other glaciofluvial soil, ie.

Muniac.

The Grand Falls mapping units differ from

Muniac units in (i) higher content of coarse fragm¬

ents, especially cobbles and coarse gravels in

Grand Falls soils and (ii) Muniac soil parent

materials arc calcareous while Grand Falls soils are

noncalcarcous.

Taxonomy

Well to moderately well drained Grand

Falls units are classified as Orthic Humo-Fcmc

Podxols for both forested and cultivated sites.

Some of the wooded sites arc poorly drained

Orthic Glcysols.

HOLMESVILLE

Extent and distribution

These soils cover 648.7 ha, occurring

mainly to the cast of the St. Andrc-Levcsque

Settlement highway (Route 255) and in the south¬

ern portion of the watershed south of St. Andre.

Holmesville soils arc the most extensive of any soil

association found in the watershed. They occupy

some 45% of the total land base.

Soil material, range in characteristics, and topog¬

raphy

The Holmesville map units consist of

deep, yellowish to olive brown, add, coarsc-tex-

turcd soils, low to moderate in natural fertility,

that have developed in deposits of compact till

with a surficial mantle of cither friable ablaiional

12

till or waicr-reworked basal till, derived mainly

from sandstone and quartzilc, with some shale,

slate, and argillitc. These soils usually consist of

40-60 cm of relatively friable, permeable, solum

material underlain by a firm, compact, slowly

permeable subsoil. Surface horizon textures for

well to moderately well drained sites arc sandy

loam to loam with some gravelly or cobbly incl¬

usions while the subsoil material is usually cobbly

loam to sandy loam. There arc usually 20-30%

coarse fragments consisting of subroumlcd to

angular cobbles and gravels. The pH of the subsoil

is less than 6.0, and more often less than 5.5.

Imperfectly (260.1 ha) and poorly (273 ha)

drained sites tend to be slightly heavier tcxturcd

than the well to moderately well drained soils in

both the friable solum and compact subsoil.

However, both fall within the limits of the above

mentioned soil texture classes.

Holmcsville soils are typically moderately

stony. This is especially true of forested sites where

stones are usually 2-10 m apart. Stone picking on

cultivated sites has reduced the presence of stones

to the point that they only hinder tillage slightly or

not at all.

A lexlural variant, with silt loam textures

throughout the profile depth and occurring in all

drainage classes, is also present in the survey area.

These units are differentiated from the modal

concept by a Icxtural abbreviation which follows

the association symbol, ie. Hosil. Another phase,

(v), of Holmcsville is characterized by 55 to less

than 100 cm of friable and compact materials

underlain by soil weathered in situ from calcareous

shale or fine grained sandstone with bedrock

present within 1 m of the surface soil (sec:

Undine). Some of the Holmcsville unils also

include weakly water rcworkcd friable material in

the solum that resembles "dirty Grand Falls* units

(Langmaid et at, 1980).

Eroded and ovcrwash phases of Holmcs¬

ville soils, 334.2 ha and 55.0 ha respectively, arc

common, indicative of the extensive soil erosion

and deposition that have taken place. In eroded

phases, the depth to the compact restricting subsoil

is less than 40 cm, and commonly less than 30 cm,

with the only friable zone being the plow layer.

Ovcrwash phases have increased thickness of

friable surface soil, at least 15 cm more than the

normal 40-60 cm. This is due to the accumulation

of surface sediments on the Ap horizon. One

shallow to bedrock phase, with less than 50 cm of

soil material over consolidated bedrock, was also

found.

Holmcsville soils arc characterized by

undulating to strongly rolling surface expressions

with slopes of 1-20%.

Land use

Well to moderately well, and some imper¬

fectly drained sites are generally used for growing

potatoes, grains, peas, and hay. Some land has

been kept under pasture. Most of the poorly

drained sites arc forested with balsam fir; black,

red, and white spruce; eastern cedar, tamarack;

while and gray birch; red maple; speckled aider,

willow, pin cherry; and black ash. Stands are over

mature with a great deal of dead trees.

Differentiating from other units

Holmcsville mapping units differ from:

Sicgas units in (i) parent material texture - Holme-

svillc sandy loam or loam versus Sicgas clay loam

or heavy loam, (ii) coarse fragments - while of

similar origins, coarse fragments arc of greater size

and in greater amounts in the Holmcsville till, (iii)

higher acidity in the Holmcsville subsoil, and (iv)

surface expression, which is undulating to strongly

rolling in contrast to the gently undulating Sicgas

landscape;

Undine units, because Holmcsville soils have more

than 55 cm of till over the residual soil/bedrock

interface; and

Grand Falls units, because of the presence of (i) a

compact till subsoil, (ii) lesser amounts of coarse

fragments and (iii) limited water rcworking effects

in Holmcsville soils.

Taxonomy

Well drained virgin Holmesville soils are

classified as Onhic Humo-Fcmc Podzols, whereas,

the imperfectly and poorly drained soils are Glcycd

Humo-Fcmc Podzols and the very poorly drained

soils arc Onhic Glcysols. The classification of

cultivated land on better drained sites is frequently

13

changed to Orthic Mclanic (Ap's pH>5.5 in

CaCy or Sombric (Ap's pH<5.5 in CaCy Bruni-

sols. When seasonal change of the pH due to

liming is considered, many of these soils arc

experiencing seasonal change in soil classification

at the Great Group level.

Soil degradation can have an equally

important impact on soil classification. Cultivated

soils often display eroded profiles manifested in a

total lack of the originally diagnostic Bf horizon.

These soils arc classified as Orthic (well drained

units) or Glcycd (imperfectly drained units) Humic

Rcgosols.

Differentiating from other units

Interval soils are readily identified by their

physical characteristics. They are friable coarse

fragment-free materials consisting primarily of

stratified fine sands and silts. Interval soils are

easily distinguished from the other water deposited

sediments. Grand Falls and Muniac, which arc

glaciofluvial soils with coarser textures and an

abundance of coarse fragments (at least 20%).

Taxonomy

Interval soils arc regularly flooded, gaining

an increment of new sediment each year, and thus

depositions have not yet developed any soil profile.

Poorly drained site conditions have led to these

soils being classified as Glcycd Regosols and Rego

Glcysols.

INTERVAL

Extent and distribution

Only one Interval mapping unit (1.8 ha)

was identified. It is in the wooded area located

below the village of St. Andrc.

Soil material, range in characteristics, and topog¬

raphy

Interval soils consist of deep, olive brown

to dark yellowish brown, medium to slightly acid,

mcdium-lcxturcd soils, high in natural fertility,

which have formed in recent alluvial deposits. The

entire depth of the soil is relatively friable, per¬

meable, stratified silt and fine sand. No coarse

fragments arc present. There are very few nat¬

urally occurring surface stones.

The mapped unit consists of a narrow

stream terrace that is very poorly drained and has

slopes of less than 5 %.

Land use

The site is wooded, with a forest of balsam

fir, black and red spruce, gray birch, red maple,

wood sorrel, starflowcr, bunchberry, yellow clinlo-

nia, wcxxl and bracken ferns, and Schrebcr's and

broom mosses.

MUNIAC

Extent and distribution

The Muniac mapping units are located in

the upper and central parts of the watershed ex¬

tending over 11.5 ha.

Soil material, range in characteristics, and topog¬

raphy

These units arc deep, light olive brown,

neutral, coarse-lcxturcd gravel soils, low to moder¬

ate in natural fertility, which have formed in loose

outwash deposits derived mainly from calcareous

slates, shales, quarlxitcs, and sandstones. The

entire depth of the soil profile (greater than 100

cm) consists of a loose, moderately to rapidly

permeable material. The subsoil is gravelly sandy

loam to gravelly or very gravelly loamy sand tcx-

turcd. The texture of the surface horizons varies

from sandy loam to loam, and even silt loam, and

may be gravelly. Coarse fragment content varies

from 20-50%, usually increasing in content with

depth. Most coarse fragments arc subroundcd

gravels, which, below the weathered zone, arc often

coated with calcium carbonate. Soil pH may

remain acidic (below pH 5.5) from the surface to

a depth of more than 80 cm before abruptly rising

14

above pH 7, or it may increase gradually with

depth. Surface stones are few, with most map units

being either nonstony or only slightly stony. Well,

moderately well, imperfectly and poorly drained

sites are mapped.

Muniac occurrence is limited to kame,

csker, and terrace type deposits with slopes ranging

from 2 to 9%.

Land use

Muniac mapping units maintain both

agricultural as well as forest production. These

units have low water storage capacity and fertility

retention. However, since they consist of small

hcctaragcs, they have usually been managed simi¬

larly to the predominant soils in a field. They are

used for potato and grain production and are more

than adequate for pasture. Forest trees include

spruces, balsam fir, trembling aspen, red maple,

and white birch, with ground vegetation of beaked

hazel, mountain maple, wood sorrel, sarsaparilla,

bunchbcny, goldthread, and twinflower.

Differentiating from other units

Muniac soils arc most oflcn confused with

the Grand Falls soils association, since both are of

glacioduvial mode of deposition. Differentiation is

based on coarse fragment content, but more

definitively on soil reaction. The Muniac soil

parent material is calcareous in comparison to the

Grand Falls subsoil which is noncalcareous. Also,

the Grand Falls soils arc usually more gravclly-

cobbly than Muniac soils.

Taxonomy

Well drained Muniac units arc Orthic

Humo-Fcrric Podzols. Imperfect to poorly drained

sites arc classified as Glcycd Humo-Fcrric Podxols

to Orlhic Humic Gleysols.

SIEGAS

Extent and distribution

Sicgas is the second most prevalent soil

association in the watershed, occupying some 4773

ha, or 33% of the area. These soils are found

almost exclusively in the northern and central

portions of the map area.

Soil material, range in characteristics, and topog¬

raphy

Sicgas soils consist of deep, light olive to

yellowish brown, slightly acidic to neutral, fine-

Icxtured soils, moderate in natural fertility, which

have formed in compact till deposits derived

mainly from sandstone, quartzite, argillite, and

shale. These soils usually have 30-50 cm of rela¬

tively friable, permeable loam, or occasionally clay

loam, surface material over a dense, compact,

extremely slowly permeable clay loam to loam till

subsoil, which is often gravelly. Both surface and

subsoil textures often vary towards silt loam.

Coarse fragments arc mostly angular to subround-

cd gravels, and usually less than 20% by volume.

While virgin forested sites are typically moderately

stony with up to 3% of the surface area occupied

by stones, most cultivated fields are only slightly

stony, due to regular stone removal (picking). Soil

pH increases with depth from an acidic surface to

neutral at 1 m, often being calcareous below.

Well and moderately well (202.0 ha),

imperfectly (177.9 ha), poorly (89.1 ha), and very

poorly (7.9 ha) drained units are all located within

the survey area.

Sicgas soils occupy surface expressions that

are undulating to gently rolling with slopes averag¬

ing 2-9%.

Eroded phases (c) arc common but not

extensive (74.7 ha). They occur on most slope

classes, even on gently inclined slopes, thus indicat¬

ing that past management can play a dominant role

in soil loss, not just slope gradient Eroded phases

have less depth to the compact subsoil than the

norm, with often only an Ap horizon remaining.

Some 11.3 ha of ovcrwash is also present Only

two units are mapped as variable depth to bedrock

with 10-100 cm of soil material over consolidated

bedrock.

Land use

Potatoes, grains, peas, and hay are the

most common crops on agricultural land that is

15

primarily well to imperfectly drained. Some arc

also left as pasturcland. A number of mapping

units with similar or worse drainage arc forested.

Balsam fir, red, white, and black spruce; sugar and

red maple; beech; yellow and white birch; striped

and mountain maple; and beaked hazel arc com¬

mon tree and shrub species present.

Differentiating from other units

The Sicgas mapping units can be

distinguished from Holmcsvillc units by (i) Sicgas

parent material texture - clay loam as opposed to

sandy loam to loam for Holmcsvillc, (ii) coarse

fragments size - Sicgas coarse fragments lend to be

gravels and less abundant than the cobbles and

gravels of Holmcsvillc material, (iii) less acidic

parent material of the Siegas soil association, and

(iv) the generally gentler sloping topography of the

Sicgas landscape.

Taxonomy

Siegas soils arc classified as Pod/A)lic

Gray Luvisol, Glcycd Podxolic Gray Luvisol, and

Orlhic Luvic Glcysol for well to moderately well,

imperfectly to poorly, and very p<x)rly drained

native soils, respectively. On the agricultural

lands, well to moderately well and imperfect to

poorly drained Sicgas mapping units arc classified

as BrunLsolic Gray Luvisol and Gleycd Bninisolic

Gray Luvisol, respectively. Some units have been

eroded to such an extent that they arc classified as

Orthic Humic RegosoLs. Very poorly drained sites

arc not under cultivation.

ST. QUENT1N

Extent and distribution

Only one unit of St. Qucntin was mapped.

It occupies 24.9 ha in the forest complex located in

the northern portion of the watershed.

Soil material, range in characteristics, and topog¬

raphy

This soil consists of forest peat material,

40-160 cm thick, but usually ranging from 40-100

cm in accumulation. St. Qucntin soils are essen¬

tially swamps. The dominant materials are moder¬

ately well decomposed (mcsic) forest peat formed

in a eulrophic, or nutrient rich environment,

resulting from strong water movement from the

deposit margins and adjacent mineral soils. The

soil matrix is a dark brown to reddish brown

colour and contains randomly distributed pieces of

wood, roots and other plant debris. Soil reaction

is medium acid to neutral. Density usually

increases with depth and permeability decreases.

Standing to gently flowing waters occur seasonally

or persist for long periods on the surface. The

substrate is usually continually waterlogged. The

unit of SL Qucntin peat that was mapped is

underlain by an olive brown clay loam tcxturcd till,

probably Sicgas parent material. The unit is gently

undulating with a 3% slope.

Land use

A forest of eastern cedar, balsam fir, black

spruce, gray birch, red maple, and trembling aspen

trees, with common sphagnum and some sedges, is

present. This area acts as a reservoir for the Black

Brook stream.

Differentiating from other units

St. Quenlin soils arc readily distinguished

from all other mapping units by the presence of

40-1 (X) cm or more of peat material over the

mineral soil.

Taxonomy

The SL Quenlin unit is classified as a

Terric Mesisol.

UNDINE

Extent and distribution

Undine units arc found mostly between

Siegas and Holmesvillc mapping units in the

central portion of the surveyed area, occupying ap¬

proximately 156.5 ha, or 11 % of the area.

16

Soil material, range in characteristics, and topog¬

raphy

Soils of the Undine Association are

moderately deep, light olive to yellowish brown,

slightly to strongly acidic, coarse to mcdium-tcx-

tured soils, moderate in natural fertility, which

have developed primarily in situ by weathering of

calcareous shale or fine grained calcareous sand¬

stone bedrock. A thin surficial mantle of till may

be present Total thickness of the soil over bedrock

is usually 65-100 cm of triable or loose, permeable

material that grades from a silt loam to loam

surface texture into a channcry silt loam subsoil.

Coarse fragments at the surface arc usually flat or

subangular gravels and often include a non-shale

component of mixed origins such as sandstones,

argillilc, slate, and quartxitc. The subsoil contains

virtually nothing but channcrs or flagstones of

highly weathered calcareous shale. On average,

coarse fragments usually range from 10-30%,

increasing in abundance with depth. Surface

stonincss ranges from slightly stony to moderately

stony, with most cultivated lands being only slightly

stony due to stone picking.

Drainages mapped arc well to moder¬

ately well (133.8 ha), and imperfectly (22.7 ha)

drained.

Included with the Undine mapping units

arc soils characterized by a thin overburden of

glacial till, usually less than 55 cm of friable to

slightly compact debris (see: Holmcsvillc) overlying

the shaly residual material. A sandy variant,

derived from fine grained weakly calcareous sand¬

stone, is mapped as UnsL Textures of these sandy

variants arc usually gravelly to nongravclly sandy

loam throughout the profile.

Both eroded (e) and ovcrwash (o) phases

of Undine were mapped. Loss of solum thickness

in the eroded phases is critical in the Undine soil

association. Any loss of soil material has the

potential of taking the site out of viable agricultur¬

al production, especially if the soil material is very

shallow to bedrock- More than half of the Undine

soils mapped are classified as eroded phases, but

only 4% as ovcrwash.

Undine mapping units occur on undulating

and rolling 3-9% slopes.

Land use

Undine soils are mostly found under

agricultural production. They are used to grow

potatoes and grains, and some are left under

pasture.

Differentiating from other units

The Undine mapping units occupy the

transition zone between the Sicgas units in the

northern and central portions of the watershed

west of the St. Andr6-Levesque Settlement highway

(Route 255), and the Holmcsville units, east of the

highway in the central and southern portions of

the watershed (Figure 4). This accounts for the

presence of some sites with thin (<55 cm) surficial

layers of friable and compact till similar to the

upper profile of the Holmesvillc units. It also

explains the mixed character of topsoil coarse

fragments on other sites.

The Undine mapping units differ from:

Sicgas units in (i) parent material consistence,

noncompact Undine versus compact Siegas, (ii)

parent material texture of sandy or silt loam in the

Undine as opposed to clay loam in Sicgas, and (iii)

the channcry shale Undine residual materials

which grade into bedrock versus the mixed gravelly

till debris of the Siegas; and

Muniac units in (i) parent material texture, chan¬

ncry silt loam, with exception of those Undine

units developed from (ine grained sandstone, as

compared to gravelly sandy loam to gravelly or

very gravelly loamy sand, and (ii) coarse fragments

of highly weathered sharp angular channel's and

flagstones of either shale or fine grained sandstone

in the Undine versus subrounded to rounded

gravels of mixed origins in the Muniac parent

material.

Taxonomy

The Undine mapping units belong to

SOIL INTERPRETATIONS FOR AGRICULTURE

This section of the report provides inter¬

pretations of the mapped soils for various agri¬

cultural land uses. Each unique map symbol listed

on the soil map (which is located in the map

pocket at the end of the report) is rated or inter¬

preted. The interpretations (Table 4) include a

general rating of soil capability for agriculture and

specific ratings for selected crop suitabilities and

management practices.

CANADA LAND INVENTORY SOIL CAPA¬

BILITY FOR AGRICULTURE

In the Canada Land Inventory (CLI) soil

capability for agriculture classification, mineral

soils are grouped into seven classes according to

their potentialities and limitations for agricultural

use (Canada Land Inventory, 1972). The Gist

three classes are considered capable of sus¬

tained production of common cultivated crops,

while the fourth is only marginal for sustained

arable culture. Classes five, six and seven are not

recommended for cultivated crops.

The class, the broadest category in the

classification, is a grouping of soils with subclasses

that have the same relative degree of limitation

or hazard. The limitation or hazard becomes

progressively greater from Class 1 to Class 7. The

soils within a capability class arc similar with

respect to degree but not necessarily to kind of

limitations in use for agricultural purposes. Each

class includes many different kinds of soils and

many of the soils within any one class may require

dissimilar management and treatment. Soils that

arc considered feasible for improvement are

classified according to their continuing limitations

after improvements have been made.

The subclass is a grouping of soils with

similar kinds of limitations and hazards. It pro¬

vides information on the kind of limitation or

conservation problem while the class indicates the

intensity of the limitation. Subclass limitations

include: adverse climate (C); undesirable soil

structure and/or low permeability (D); past dam¬

age from erosion (E); low fertility (F); inundation

by streams (I); moisture limitation (M); consoli¬

dated bedrock (R); topography (T); and excess

water (W).

SOIL SUITABILITY FOR SELECTED CROPS

AND MANAGEMENT PRACTICES

Guidelines for assessing the soil and

landscape suitability tor selected crops and man¬

agement practices are provided in Appendix 2,

Tables A2-1 to A2-8. The major soil and land¬

scape properties influencing the given uses are

listed along with four degrees of soil suitability -

good (G), fair (F), poor (P) and unsuitable (U).

Good (G) - The soil is relatively free of

problems that hinder crop production and soil

management, or the limitations that do occur

can be easily overcome.

Fair (F) - Moderate soil and/or landscape

limitations exist, but they can be overcome with

good crop management and improvement prac¬

tices or special techniques.

Poor (P) - Severe soil and/or landscape

limitations exist which will be difficult and costly

to overcome. Crop production is severely

hindered and the efficacy of land improvement

practices is low.

Unsuitable (U) - The inputs required to utilize

or improve these soils for crop production is too

great to be justified under existing economic

conditions.

Each unique map symbol is rated for soil

suitability for alfalfa, forages, pasture, peas, pota¬

toes, spring cereals (wheat, oats, barley), subsurface

drainage, and deep ripping. These ratings, along

with an assessment of the Canada Land

Inventory soil capability for agriculture, are pro¬

vided below in Table 4. The degree of soil suit¬

ability is based on the most restrictive soil property

or properties, given existing conditions. The major

soil properties influencing use are also provided

along with the degree of soil suitability. Major soil

properties influencing use for the rated crops and

management practices are: depth to bedrock

(b); depth of friable soil, or undesirable soil

structure and slow permeability (d); Hooding, or

inundation (i); stoniness (p); rockiness (r); slope,

or topography (l); drainage, or wetness (w); and

soil texture (x).

APPENDIX 1

MORPHOLOGICAL DESCRIPTIONS AND

ANALYSES FOR SOIL ASSOCIATIONS

This section lists in alphabetical order

selected profile descriptions for the more import¬

ant members of soil associations mapped on the

Black Brook Watershed. Results of physical and

chemical analyses are also provided.

The soil profile morphology is described

in defined terminology according to established

guidelines (Agriculture Canada Expert Committee

on Soil Survey, 1983). Classification is based on

the Canadian System of Soil Classification. Profile

descriptions usually include: horizon designations

and depths, colour, texture, mottling (where pres¬

ent), structure, consistence, and coarse fragments.

Site parameters arc also recorded: location, eleva¬

tion, parent material, slope, physiographic position,

aspect, surface expression, drainage, slonincss,

rockincss, and present land use.

Chemical and physical analytical procedur¬

es used arc those specified in Shcldrick (1984).

Determinations consist of pH in Cad^ (2.1 84-

(X)l), % organic carbon (2.6 84-013), % nitrogen

(LECO furnace), sodium pyrophosphate extract-

able Fc and Al (2.5 84-012), ditluonite extractable

Fc and Al (2.5 84-010), cation exchange capacity

and exchangeable base cations Ca, Mg and K (2.3

84-004), carbonates (2.4 84-009), available P (2.7

84-018), electrical conductivity (2.2 84-003), par¬

ticle size distribution with sand tractions (3.1 84-

026), bulk density with coarse fragments (3.2 84-

029), saturated hydraulic conductivity (3.5 84-037),

and % water retention by volume at given tensions

(3.4 84-035 & 84-036).

Soil pH values referred to in the text of

this report arc for water determined values unless

otherwise staled.

APPENDIX 2

RATING GUIDELINES FOR SOIL SUITABIL¬

ITY FOR SELECTED CROPS AND MANAGE¬

MENT PRACTICES

This appendix lists the interpretive

guidelines that have been used to rate the soil map

units identified in the Black Brook Watershed.

The guidelines arc in tabular format. Soil and

landscape conditions that impact on the intended

use arc rated from good to unsuitable. The soil

suitability is determined by the most restrictive

(least suitable) rating assigned to any of the listed

soil properties. The properties listed are dcdncd

in cither the Canadian System of Soil Classification

(Agriculture Canada Expert Committee on Soil

Survey, 1987) or the Canada Soils Information

System (CanSIS) (Agriculture Canada Expert

Committee on Soil Survey, 1983).

The objective of this appendix is to docu¬

ment the approach used to rate the soil map units

for the selected uses. These rating guidelines arc

considered as "best approximations". The soil

rating indicates the severity of the limitation or

lack of suitability of the soil if it is used without

corrective or precautionary measures. As more is

learned about soil behavior and crop response,

these rating guidelines may be amended. Applica¬

tions of new technologies may change crop yields

and the relative suitabilities of the soils for various

uses. The soil interpretations provided here are

only examples of how soil resource information

can be used in land related decision making.

Numerous other interpretations can be made from

this data.

The rating guidelines listed here are for:

Crop suitability - alfalfa

- forages

- pasture

- peas

- potatoes

- spring cereals

Management practices - subsurface drainage

- deep ripping
