TISDALE SERIES

The Tisdale series consists of moderately deep, well drained soils that formed in alluvium from mixed sources. Tisdale soils are on low terraces and have slopes of 0 to 2 percent. The annual precipitation is about 18 inches and the annual temperature is about 62 degrees F.

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, thermic Typic Haploxerolls

TYPICAL PEDON: Tisdale clay loam - on a nearly level slope of less than 1 percent in an irrigated prune orchard at 37 feet elevation. (Colors are for dry soil unless otherwise noted. When described on July 6, 1977, the soil was dry from 0 to 7 inches and moist below 7 inches.)

Ap--0 to 7 inches; brown (10YR 5/3) clay loam, dark brown (10YR 3/3) moist; weak medium subangular blocky structure; slightly hard, friable, slightly sticky and plastic; common very fine and fine roots; many very fine and fine tubular pores; slightly alkaline (pH 7.5); clear smooth boundary. (5 to 9 inches thick)

A--7 to 11 inches; brown (10YR 5/3) clay loam, dark brown (10YR 3/3) moist; moderate medium subangular blocky structure; slightly hard, friable, slightly sticky and plastic; common very fine and fine roots; many very fine and fine tubular pores; slightly alkaline (pH 7.5); clear wavy boundary. (4 to 10 inches thick)

Bt1--11 to 21 inches; pale brown (10YR 6/3) clay loam, brown (10YR 4/3) moist; moderate medium subangular blocky structure; hard, friable, sticky and plastic; few fine and medium roots; many very fine and fine and few medium tubular pores; few thin clay films on ped faces and in pores; moderately alkaline (pH 8.0); clear wavy boundary. (5 to 10 inches thick)

Bt2--21 to 31 inches; light yellowish brown (10YR 6/4) clay loam, dark yellowish brown (10YR 4/4) moist; moderate medium subangular blocky structure; hard, firm, very sticky and plastic; few very fine roots; many very fine and fine tubular pores; few thin clay films on ped faces and in pores; moderately alkaline (pH 8.0); abrupt wavy boundary. (5 to 11 inches thick)

2Cr--31 to 40 inches; very pale brown (10YR 8/3) siltstone, pale brown (10YR 6/3) moist; massive, very hard and extremely firm; common very fine tubular pores; slightly effervescent, lime occurs in common fine seams; moderately alkaline (pH 8.0).

TYPE LOCATION: Sutter County, California; approximately 7 miles south of Yuba City on George Washington Blvd., then west 0.25 miles on farm road, then 400 feet south into prune orchard; 800 feet north and 2,500 feet east from the southwest corner of section 19, T. 14 N., R. 3 E.

RANGE IN CHARACTERISTICS: Depth to a paralithic contact is 20 to 40 inches. The mean annual soil temperature is 60 degrees to 65 degrees F. The difference between average July and average January soil temperature is 30 degrees to 33 degrees F. The 6 to 18 inch soil moisture control section is dry in all parts from June through October unless irrigated and is moist in some or all parts from November thru May. Clay content ranges from 20 to 35 percent.

The A horizon has dry colors of 10YR 5/2 or 5/3 and moist colors of 10YR 3/2 or 3/3. It is loam or clay loam. Reaction is neutral to slightly alkaline.

The Bt horizon has dry colors of 10YR 5/3, 5/4, 6/3 or 6/4 and moist colors of 10YR 4/3, 4/4, 3/3 or 3/4. It is loam or clay loam with a 1 to 3 percent (absolute) clay increase over the A horizon. Reaction is neutral to moderately alkaline.

Some pedons have C horizons.

COMPETING SERIES: These are the Liveoak and Saurin series and the Andregg, Pfeiffer, San Andreas and Walong series in another family. Andregg, Pfeiffer, San Andreas and Walong soils are coarse-loamy and are on uplands. Saurin soils have a difference between mean summer and mean winter soil temperature of 12 to 15 degrees F and are medium or slightly acid. Liveoak soils have bedrock at greater than 60 inches.

GEOGRAPHIC SETTING: Tisdale soils are on low terraces. Slopes are 0 to 2 percent. The soils formed in alluvium from mixed sources deposited over unrelated siltstone. Elevations are 20 to 80 feet. The climate is subhumid with hot dry summers and cool moist winters. Mean annual precipitation is 17 to 20 inches. Mean January temperature is 45 degrees F; mean July temperature is 77 degrees F; and mean annual temperature is 60 degrees to 64 degrees F. Frost-free season is 260 to 280 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Conejo, Gridley and Marcum soils which are on low terraces. Conejo soils are greater than 60 inches deep. Gridley soils have a fine argillic horizon. Marcum soils are 40 to 80 inches deep to a paralithic contact.

DRAINAGE AND PERMEABILITY: Well drained; very slow runoff; moderately slow permeability.

USE AND VEGETATION: Used for irrigated small grains, row crops and irrigated orchards.

DISTRIBUTION AND EXTENT: Southeastern portion of the Sacramento Valley. Soils are not extensive.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California

SERIES ESTABLISHED: Sutter County, California 1983. The source of the name comes from Tisdale Weir.
