Fargo soil series
A representative profile of Fargo silty clay. The high content of clay and the shrink-swell potential of this soil cause cracking during dry periods. The cracking results in tonguing of the darker material from the surface layer into the subsoil. The tongues in this profile extend from a depth of 40 to 60 centimeters. (Soil Survey of Polk County, Minnesota; by Charles T. Saari and Rodney B. Heschke, Natural Resources Conservation Service)
The Fargo series consists of very deep, poorly drained and very poorly drained, slowly permeable soils that formed in calcareous, clayey lacustrine sediments. These soils are on glacial lake plains, floodplains, and gently sloping side slopes of streams within glacial lake plains. Slopes range from 0 to 2 percent. Mean annual air temperature is about 5 degrees C, and mean annual precipitation is about 575 millimeters.
TAXONOMIC CLASS: Fine, smectitic, frigid Typic Epiaquerts
Clay content of the particle size control section - typically 40 to 60 percent; however in some pedons material with less clay in the lower part of the control section results in an average between 35 and 40 percent.
Sand content of the particle size control section -- less the 15 percent fine sand and coarser
Rock fragments -- 0 percent
Thickness of the mollic epipedon -- 15 to 55 centimeters
Depth to carbonates -- 41 to 58 centimeters
Saline phases are recognized
USE AND VEGETATION: The soils are nearly all cropped to corn, small grains, soybeans and sugar beets. Native vegetation is western wheatgrass, Kentucky bluegrass and a variety of forbs.
DISTRIBUTION AND EXTENT:
Physiographic Division-Interior Plains
Physiographic Province-Central Lowland
Physiographic section-Western Lake section
MLRA--Red River Valley of the North (56);
Central Black Glaciated Plains (55B)
Northern Black Glaciated Plains (55A)
also used in a small extent of glaciolacustrine areas in west-central Montana.
LRR-Northern Great Plains Spring Wheat Region (F)
Extent--large
