Medoc soil series

A representative soil profile of the Medoc soil series. (Soil Survey of Jasper County, Missouri; by Alan C. Peer, Natural Resources Conservation Service)

 

The Medoc series consists of very deep, somewhat poorly drained soils that formed in a thin mantle of silty loess over residuum of the Cherokee Prairies (MLRA 112). Medoc soils are on uplands and the slope ranges from 0 to 1 percent. Mean annual precipitation is 40 inches and the mean annual temperature is 57 degrees F.

 

TAXONOMIC CLASS: Fine, mixed, active, thermic Aeric Albaqualfs

 

Soil moisture control section: aquic

Depth to abrupt textural change: 12 to 20 inches

Depth to albic horizon: 6 to 10 inches

Depth to argillic horizon: 12 to 20 inches

Depth to redox concentrations: 6 to 10 inches

Depth to redox depletions: 14 to 32 inches

Depth to episaturation: 12 to 18 inches from February to April

Particle-size control section (weighted average):

Clay content: 35 to 60 percent

Sand content: 6 to 20 percent

 

USE AND VEGETATION: Most areas are used for cropland. A few areas are used for native hayland or pasture. Principal crops are wheat, corn, milo, and soybeans. Native vegetation is prairie grasses, mainly big and little bluestem.

 

DISTRIBUTION AND EXTENT: Southwest Missouri and possibly Southeast Kansas and Northeast Oklahoma. The soils are of minor extent.
