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.

central parts, and few hummocks. In the lower
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

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
