The Feliz series consists of very deep, well drained soils that formed in alluvium derived from mixed rock sources. These soils are on flood plains. Slopes range from 0 to 5 percent. The mean annual precipitation is about 50 inches, and the mean annual air temperature is about 55 degrees F.

The Feliz soils in this survey area have brighter colors, lower base saturation, and lower pH than are defined as the range for the series. These soils are classified as fine-loamy, mixed, thermic Cumulic Haploxerolls.

A2—5 to 18 inches; brown (10YR 5/3) loam, dark brown (10YR 3/3) moist; strong fine and medium granular structure; slightly hard, friable, slightly sticky and slightly plastic; many very fine roots; many very fine and fine tubular and interstitial pores; 10 percent subrounded gravel; slightly acid (pH 6.3); gradual wavy boundary.

A3—18 to 27 inches; brown (10YR 5/3) loam, dark brown (10YR 3/3) moist; moderate fine and medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; common very fine roots; common very fine and fine tubular and interstitial pores; 10 percent subrounded gravel; slightly acid (pH 6.3); clear wavy boundary.

C1—27 to 37 inches; pale brown (10YR 6/3) loam, dark brown (10YR 3/3) moist; moderate medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; common very fine roots; common very fine tubular pores; 10 percent subrounded gravel; slightly acid (pH 6.4); clear wavy boundary.

C2—37 to 43 inches; pale brown (10YR 6/3) loam, dark brown (10YR 3/3) moist; moderate fine and medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; few very fine roots; many very fine tubular pores; 5 percent subangular gravel; slightly acid (pH 6.4); gradual smooth boundary.

2C3—43 to 60 inches; dark yellowish brown (10YR 4/4) clay loam, dark brown (10YR 3/3) moist; strong fine and medium subangular blocky structure; hard, firm, sticky and plastic; few very fine roots; common very fine tubular pores; 5 percent subrounded gravel; slightly acid (pH 6.2).

The depth to bedrock is more than 60 inches. The mollic epipedon is 20 to 30 inches thick and has 2 to 5 percent organic matter. The mean annual soil temperature ranges from 59 to 62 degrees F. The soil between the depths of 7 and 21 inches is moist in all parts from November 1 to May 1 and is dry in all parts from June 15 to October 1 in most years. Reaction is moderately acid or slightly acid throughout.

The A horizon has color of 10YR 4/3 or 5/3. Moist color is 10YR 2/2, 3/2, or 3/3. The content of clay ranges from 18 to 27 percent. The content of gravel ranges from 0 to 15 percent. Base saturation ranges from 50 to 75 percent.

The C horizon has color of 10YR 4/4, 5/3, 5/4, 6/3, or 6/4. Moist color is 10YR 3/3, 3/4, or 4/4. The texture is loam or clay loam that contains 20 to 30 percent clay. The content of gravel typically ranges from 0 to 15 percent. Some pedons have gravelly or very gravelly textures below a depth of 40 inches. Base saturation ranges from 60 to 85 percent.
