GRENVILLE SERIES
The Grenville series consists of very deep, well drained soils formed in calcareous, dense till. They are nearly level to moderately steep soils on low hills and ridges. Slope ranges from 0 to 25 percent. Mean annual temperature is 7 degrees C. (45 degrees F.), and mean annual precipitation is 1000 mm (39 in).
TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, frigid Typic Eutrudepts
TYPICAL PEDON: Grenville loam, in a hay field on a 3 to 8 percent slope. (Colors are for moist soil unless otherwise stated.)
Ap-- 0 to 23 cm; dark brown (10YR 3/3) loam; moderate medium granular structure; very friable; many fine roots; 5 percent rock fragments; slightly acid; abrupt smooth boundary. (4 to 10 in thick)
Bw1-- 23 to 30 cm; brown (10YR 4/3) loam; moderate medium subangular blocky structure; very friable; common fine roots; 10 percent rock fragments; slightly acid; gradual smooth boundary.
Bw2-- 30 to 43 cm; dark yellowish brown (10YR 4/4) loam; moderate medium subangular blocky structure; very friable; few fine roots; 10 percent rock fragments; neutral; gradual smooth boundary. (Combined thickness of the Bw horizon is 8 to 30 in.)
C-- 43 to 89 cm; brown (10YR 4/3) gravelly fine sandy loam; massive; friable; few fine roots; 20 percent rock fragments; moderately alkaline, strongly effervescent; clear smooth boundary. (0 to 15 in thick)
Cd-- 89 to 183 cm; brown (10YR 4/3) gravelly fine sandy loam; massive; firm; 20 percent rock fragments; common medium distinct gray (10YR 5/1) mottles; strongly effervescent; moderately alkaline.
TYPE LOCATION: Clinton County, New York; Town of Chazy, 700 feet north of County Route 23 (Old route 191), and 3080 feet west of Lake Shore Road; USGS Champlain, NY topographic quadrangle; Latitude 44 degrees, 53 minutes, 15 seconds N. and Longitude 73 degrees, 23 minutes, 25 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: Thickness of the solum and depth to carbonates range from 38 to 102 cm (15 to 40 in). Depth to densic material is 51 to 102 cm (20 to 40 in). Depth to bedrock is more than 152 cm (60 in). Rock fragments, mainly gravel and cobbles, range from 5 to 35 percent by volume in the solum, and from 5 to 50 percent in the substratum. Some pedons have few to common redoximorphic concentrations above the densic substratum.
The A horizon has hue of 10YR, value of 2 to 4, and chroma of 2 or 3. It is silt loam, loam, fine sandy loam, or sandy loam or their gravelly analogues in the fine-earth fraction. Reaction ranges from strongly acid to slightly acid.
The Bw horizon has hue of 5YR to 10YR, value of 3 to 5, and chroma of 3 to 6. It is silt loam, loam, fine sandy loam, or sandy loam or their gravelly analogues in the fine-earth fraction. Reaction ranges from moderately acid to neutral.
The BC horizon has hue of 7.5YR to 2.5Y, value of 3 to 5, and chroma of 2 or 3. It is silt loam, loam, fine sandy loam, or sandy loam or their gravelly analogues in the fine-earth fraction. Reaction is neutral or slightly alkaline.
The Cd horizon has hue of 7.5YR to 2.5Y, value of 3 to 5, and chroma of 2 or 3. It is silt loam, fine sandy loam, sandy loam, or loam or their gravelly or very gravelly analogues in the fine-earth fraction. Reaction is slightly alkaline or moderately alkaline and it is calcareous. Some pedons have a friable C layer up to 51 cm (20 in) thick above the Cd.
COMPETING SERIES: The
Sisseton series is the only other series in the same family. Sisseton soils are from outside of
Land Resource Region R and formed in areas that receive 457 to 610 mm (18 to 24 in) of annual precipitation.
Dover and
Nellis are in related series which are mesic.
GEOGRAPHIC SETTING: Grenville soils are nearly level to moderately steep. They are on low hills and ridges on till plains, and in many places associated with lacustrine deposits in nearby depressions. Slope ranges from 0 to 25 percent. Elevation ranges from 30 to 240 meters (98 to 780 feet) above sea level. These soils formed in deposits dominated by dolomitic limestone with varying proportions of calcic limestone and granitic material. Mean annual precipitation ranges from 790 to 1490 mm (31 to 59 in), and mean annual temperature ranges from 4 to 9 degrees C (39 to 48 degrees F). The frost free period ranges from 100 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Hogansburg,
Kalurah,
Malone,
Nehasne,
Pyrities,
Raquette,
Runeberg, and
Waddington soils. Hogansburg, Malone, and Runeberg soils occupy lower topographic positions and are drainage associates. Nehasne soils are less than 40 in to bedrock. Pyrities and Kalurah soils do not have free carbonates within a depth of 40 in. Raquette soils have a sandy particle-size control section. Waddington soils have a loamy-skeletal particle-size control section.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The potential for surface runoff is medium to rapid. Saturated hydraulic conductivity is moderately high or high in the surface and upper subsoil, moderately low through high in the lower subsoil and friable substratum, and low through moderately high in the dense substratum.
USE AND VEGETATION: Most areas have been cleared and are used for growing pasture, hay, small grain, and corn. Woodlots contain sugar maple, basswood, hophornbeam, and associated northern hardwoods.
DISTRIBUTION AND EXTENT: St. Lawrence and Champlain Valleys of New York. MLRA 142. The series is moderately extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.
SERIES ESTABLISHED: Franklin County, New York, 1952.
REMARKS: Diagnostic horizons and other features recognized in this pedon are:
a. Ochric epipedon - the zone from the soil surface to a depth of 23 cm (9 in) (Ap horizon).
b. Cambic horizon - the zone from 23 to 43 cm (9 to 17 in) (Bw1 and Bw2 horizons).
c. Eutrudepts great group - the zone between 30 to 43 cm (12 to 17 in) has a base saturation greater than 60 percent (Bw2 horizon).
d. Typic subgroup - saturation within 102 cm (40 in) of the mineral surface is less than 30 days in most years.
ADDITIONAL DATA: Data is available for the following pedons: S81NY089001, S81NY089022, S81NY089028, S81NY089029, S85NY019020 .
