Dixonville soil series

The Dixonville series consists of moderately deep, well drained soils formed in clayey colluvium and residuum derived from basalt. Dixonville soils are on hills. Slopes are 3 to 60 percent.

 

TAXONOMIC CLASS: Fine, mixed, superactive, mesic Pachic Ultic Argixerolls

 

The mean annual soil temperature is 51 to 56 degrees F. The soils are usually moist but are dry between 4 and 12 inches for 45 to 60 consecutive days during the summer months within MLRA 2 but ranges to 90 days in MLRA 5. Depth weakly or moderately cemented basalt bedrock is 20 to 40 inches. The solum is 20 to 40 inches thick. The pscs has 40 to 55 percent clay, 0 to 35 percent rock fragments and 0 to 10 percent pararock fragments. The mollic epipedon is 20 to 36 inches thick.

 

USE AND VEGETATION: These soils are used for native pasture, hay, small grains, row crops, sweet cherries, filberts, and woodland. Oregon white oak and Douglas fir dominate the tree canopy. Other species are bigleaf maple and grand fir. The understory vegetation is western brackenfern, common snowberry, western hazelnut, Pacific poison-oak, and baldhip rose.

 

DISTRIBUTION AND EXTENT: Foot slopes of the Coast Range and Cascade Range in western Oregon; MLRA 2, 5. The series is moderately extensive.
