  1. Soil Classification ComparisonHall County, Georgia University of Florida Soil Pedology, Spring 2010 Prof: Willie Harris By: Sam Vacca 4/22/10

  2. Site Location • Hall County, Georgia • Nearest City: Gainesville, Georgia • Physiographic Province: Piedmont • Annual Precipitation: 54.75 inches • Annual Temperature: 61 degrees F • Predominant Land Use: Agriculture

  3. Soil Profile Locations

  4. Site Topography

  5. Site Landscape

  6. Soil Survey Cc (Pink) – Cartecay and Chewacla Undifferentiated Group (Floodplains; 0 – 2% Slopes; High Water Table) PaE (Blue) – Pacolet Soil Series (Sandy Loam; 15-25% Slopes; Weathered Rock)

  7. Soil Profile 1 Perennial Stream Alluvial System Broad Floodplain Receiving Waterway Degraded Channel Channel Incision Lack of Vegetation Heavy Cattle Use

  8. Soil Profile 1 MORPHOLOGY Ap1 -- 0-11 inches; dark grayish brown (10yr 4/2); clay loam; weak sub-angular blocky structure; friable; clear smooth boundary; many roots. Ap2 -- 11-18 inches; dark grayish brown (10yr 4/2); clay loam; moderate sub-angular blocky structure; friable; abrupt smooth boundary. Bw1 -- 18-28 inches; yellowish red (5yr 4/6); silt clay loam; strong platy structure; friable; gradual smooth boundary. Bw2 – 28-39.5 inches; yellowish red (5yr 5/8); loamy sand; structureless massive structure; very friable; distinct smooth boundary. Btg1 – 39.5-67 inches; dark grayish brown (2.5y 4/2); silt loam; strong sub-angular blocky structure; friable; gradual smooth boundary; redoximorphic features (low chroma, Fe concentrations/mottles). Btg2 – 67-70 inches; black (2.5y 2.5/1); silt loam; strong angular blocky structure; friable; abrupt smooth boundary; redoximorphic features. C1 – 70-72 inches; yellowish brown (10yr 5/4); sand; structureless single grain structure; loose; abrupt smooth boundary; line of oxidized Fe above and below. C2 – 72-76+ inches; dark gray (10yr 4/1); sand; structureless single grain structure; loose; gravelly.

  12. Soil Profile 2 Perennial Stream Colluvial System Steep Riparian Slopes Tributary to Stream 1 Stable Channel Vegetated Banks No Cattle Use

  13. Soil Profile 2 MORPHOLOGY A -- 0-10 inches; very dark grayish brown (10yr 3/2); loam; weak granular structure; friable; gradual smooth boundary; many roots. Bt1 – 10-36 inches; brown (7.5yr 4/4); clay loam; strong angular blocky structure; firm; diffuse smooth boundary. Bt2 – 36-48 inches; brown (7.5yr 4/3); loamy sand; structureless single grain structure; loose; diffuse smooth boundary; gravelly; C1 – 48-60 inches; brown (7.5yr 4/3); loamy sand; structureless single grain structure; loose; diffuse smooth boundary; very cobbly. C2 – 60-68+ inches; no true matrix color; sandy loam (when crushed); moderate platy structure; firm; clear smooth boundary.
