RYDER SERIES
The Ryder series consists of moderately deep well drained soils. They formed in residuum weathered from thin bedded shaly limestone or calcareous shale. They are on convex upland slopes of 0 to 65 percent. Saturated hydraulic conductivity is moderately high to high. Mean annual precipitation is 43 inches. Mean annual temperature is 52 degrees F.
TAXONOMIC CLASS: Fine-loamy, mixed, semiactive, mesic Ultic Hapludalfs

TYPE LOCATION: Franklin County, Pennsylvania; in a field 3/4 mile south of Waynesboro, Washington Township, 2000 feet northwest of junction of Pennsylvania Township Routes T363 and T368, 1600 feet north of T363; USGS Smithsburg topographic quadrangle; lat. 39 degrees 43 minutes 54 seconds N. and long. 77 degrees 35 minutes 14 seconds W.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 36 inches. Depth to bedrock ranges from 24 to 40 inches. Rock fragments of white quartzite, limestone, or shale range from 0 to 25 percent in the solum and from 25 to 75 percent in the C horizon. Reaction ranges from strongly acid through neutral in the solum and from moderately acid through neutral in the C horizon. The most common clay mineral is illite. Other minerals of chlorite and interstratified chlorite-vermiculite occur in small quantities.
The Ap horizon has hue of 10YR, value of 3 through 5, and chroma of 2 to 4. Fine-earth texture is silt loam or silty clay loam.
The B horizon has hue of 7.5YR through 2.5Y, value of 5 or 6, and chroma of 4 through 6. Fine-earth textures are loam, silt loam, and silty clay loam. It commonly has 18 to 30 percent clay and 45 to 65 percent silt.
The C horizon has hue of 7.5 YR or 2.5Y, value of 4 or 5, and chroma of 3 through 6. Fine-earth textures are loam, silt loam, or silty clay loam.
COMPETING SERIES:
Bolton,
Bookwood,
Carpenter,
Renox and
Washington series are in the same family. Bolton soils formed in material weathered from interbedded limestone and sandstone bedrock on mountain side slopes. Bookwood soils are moderately deep and well drained soils that formed from residuum derived from interbedded limestone and shale. Carpenter soils formed in moderately permeable loamy colluvium over slowly permeable residuum of weathered shale or siltstone. Renox sols are very deep and formed in loamy colluvium or alluvium from interbedded siltstone, shale, limestone, and sandstone. Washington soils formed in old glacial drift (pre-Wisconsin Age) or colluvium derived mainly from limestone and granitic gneiss.

Williamsburg soils are in a related families. Arcola soils have hues redder than 7.5YR throughout solum and substratum. Athol and Penn soils have Bt horizons with hues redder than 7.5YR. Brecknock soils have solum thickness of less than 40 inches and depth to bedrock of less than 60 inches. Caribel, Hayter, Manassas, Middleburg, Neshaminy, Panorama and Sudley, soils all have bedrock at depths greater than 40 inches. Cateache, Culleoka, Frondorf, Loudonville, Mechanicsburg, Penn, and Spriggs series have a lithic or paralithic contact at depths of less than 4O inches. Cateache soils have hues redder than 7.5YR below the surface horizons. Culleoka soils do not have rock fragments of weathered limestone and quartzite. Door soils have a mollic epipedon from 10 to 20 inches. Duffield soils are formed in residuum of impure limestone. Dumfries soils have a higher mean annual temperature and also have bedrock at greater than 20 feet. Ebbing soils have hue of 7.5YR or browner in the lower part of the series control section. Fredericktown soils formed in early Wisconsian or Illinoian age outwash, with or without a thin loess mantle, on stream terraces and kame terraces. Frondorf soils are very strongly acid or strongly acid throughout the soil, and have rock fragments dominantly of sandstone, siltstone, and shale. Grayford and Lamotte soils have a loess capping. Kell soils are more acid than moderately acid in the lower one-fourth of the control section. Legore, Myersville, and Westmoreland soils have solum thickness of less than 40 inches. Legore soils have rock fragments dominated by diabase or diorite and saprolite within a depth of 40 inches. Loudonville soils have erratics and rock fragments are dominantly of sandstone. Mechanicsburg soils have a lithologic discontinuity between 20 and 40 inches. Morrison soils formed in residuum of weathered noncalcareous sedimentary rock and have hue of 7.5YR or yellower in the Bt2 horizon. Oatlands soils have rock fragments of conglomerate. Pasturerock soils are very deep to bedrock and in the particle-size control section have 5 to 35 percent gravel and 0 to 15 percent cobbles.
