Little Wood soil series

The Little Wood series consists of very deep, well drained soils that formed in loess, alluvium, and residuum from mixed sources. Little Wood soils are on fan terraces, stream terraces, and dissected alluvial terraces. Slopes are 0 to 30 percent. Permeability is moderate in the upper part and very rapid below. The average annual precipitation is about 14 inches and the average annual air temperature is about 43 degrees F.

 

TAXONOMIC CLASS: Loamy-skeletal, mixed, superactive, frigid Ultic Argixerolls

 

Average annual soil temperature - 42 to 47 degrees F.

Average summer soil temperature - 60 to 65 degrees F.

Mollic epipedon thickness - 10 to 19 inches

Depth to sandy-skeletal layer and base of the argillic - 21 to 34 inches

Reaction - moderately acid to neutral

Base saturation - 50 to 75 percent

 

USE AND VEGETATION: Dry cropland, irrigated cropland, rangeland, and housing sites. Alfalfa hay, pasture, and small grains are the principle crops. Vegetation is bluebunch wheatgrass, Idaho fescue, Sandberg bluegrass, needlegrasses, mountain big sagebrush, and basin big sagebrush.

 

DISTRIBUTION AND EXTENT: Little Wood soils are moderately extensive in south-central Idaho.
