3/31/25, 1:08 PM Official Series Description - BOONTON Series LOCATION BOONTON NJ+NY Established Series Rev. WDB-SG-SMF 12/2012 BOONTON SERIES The Boonton series consists of deep or very deep moderately well and well drained soils formed in till on uplands. They are moderately deep to a fragipan. Slope ranges from 0 to 50 percent. Saturated hydraulic conductivity is moderately low to high in the mineral soil above the fragipan, low or very low in the fragipan, and low to high below the fragipan. Mean annual temperature is about 12 degrees C and mean annual precipitation is about 1090 millimeters. TAXONOMIC CLASS: Coarse-loamy, mixed, active, mesic Oxyaquic Fragiudalfs TYPICAL PEDON: Boonton silt loam idle pasture, at an elevation of about 155 feet. (Colors are for moist soil.) Ap -- 0 to 20 centimeters; brown (10YR 4/3) silt loam; moderate fine and medium granular structure; very friable; many fine and common medium and coarse roots; many fine and medium tubular pores; common uncoated sand grains; 5 percent subangular stones, cobbles, and gravel; very strongly acid; clear smooth boundary. (15 to 25 centimeters thick.) BA -- 20 to 38 centimeters; dark yellowish brown (10YR 4/4) fine sandy loam; weak medium subangular blocky structure; very friable; many fine and common medium and coarse roots; common fine tubular pores; many coated sand grains; 10 percent gravel and cobbles; very strongly acid; clear wavy boundary. (0 to 23 centimeters thick.) Bt1 -- 38 to 58 centimeters; brown (7.5YR 4/4) gravelly loam; moderate medium subangular blocky structure; friable; common fine and few medium and coarse roots; common fine tubular pores; common faint clay films on horizontal and vertical faces of peds; few distinct clay films lining pores; 15 percent gravel, 2 percent cobbles; strongly acid; clear wavy boundary. Bt2 -- 58 to 76 centimeters; brown (7.5YR 4/4) gravelly fine sandy loam; weak coarse and medium subangular blocky structure; friable; common fine and few medium and coarse roots; few fine tubular pores; few faint clay films on horizontal and vertical faces of peds; 20 percent gravel, 2 percent cobbles; strongly acid; abrupt smooth boundary. (Combined thickness of the Bt horizons is 30 to 56 centimeters.) Btx -- 76 to 127 centimeters; dark reddish brown (5YR 3/4) gravelly sandy loam; strong very thick platy structure; very firm, brittle; few roots

thickness of the Bt horizons is 30 to 56 centimeters.) Btx -- 76 to 127 centimeters; dark reddish brown (5YR 3/4) gravelly sandy loam; strong very thick platy structure; very firm, brittle; few roots between peds; few fine vesicular pores; few distinct clay films on faces of peds; 20 percent gravel, 2 percent cobbles and stones; few fine distinct black (N 2/0) and few fine distinct brown (7.5YR 5/2) areas of iron depletion; strongly acid; gradual wavy boundary. (25 to 76 centimeters thick.) Cd -- 127 to 165 centimeters; dark reddish brown (SYR 3/4) gravelly sandy loam; weak medium and thick platy structure in upper part and massive in lower part; very firm, brittle; 25 percent gravel, 2 percent cobbles; slightly acid. TYPE LOCATION: Passaic County, New Jersey; Totowa Borough, 0.2 mile northeast of Totowa Road on Brookmans Lane, 585 feet east of Brookmans Lane in idle pasture. USGS Paterson quadrangle; Latitude 40 degrees, 54 minutes, 44 seconds N, Longitude 74 degrees, 12 minutes, 11 seconds W, NAD 1927. RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 91 to more than 153 centimeteres. Depth to bedrock is more than 122 centimeters. The top of the fragipan is at a depth of 50 to 91 centimeters. In most pedons, the upper part of the fragipan is part of the argillic horizon. Few or common redoximorphic features are in some pedons, but depletions with chroma of 2 or less are absent within 40 centimeters of the mineral soil surface.Rock fragments of mostly rounded gravel occur throughout the soil, and range from 0 to 35 percent in individual horizons. Stones and cobbles range from 0 to 10 percent in the solum and from 0 to 20 percent in the substratum. Reaction is strongly acid to extremely acid in the upper part of the solum. It ranges from strongly acid to slightly acid in the lower part of the solum, and from moderately acid to neutral in the C horizon. Some pedons have O horizons with hue of 10YR, value of 2 or 3, and chroma of 1 or 2. In lieu texture is slightly decomposed to highly decomposed plant material. The Ap or A horizon has hue of 7.5YR or 10YR, value of 2 to 5, and chroma of 1 to 4. Texture of the Ap or Ahorizon is silt https://soilseries.sc.egov.usda.gov/OSD_Docs/B/BOONTON. html 113
