I~ RAVOLA VERY FIPtE SANDY~LOAbi, 0 to 2 percent slopes, Class I Land (Rf) This soil-occurs either along washes or arroyas extending from the north or on broad coalescing alluvial fans. The alluvial materia_1 fram which the soil has developed was derived frog sandstone and shale and ranges from 4 to 20 feet deep. This soil is much]:iss Ravola fine sandy loam, 0 to 2 percent slopes, but is generally sore uniformly level. The texture is prevailingly very fine sandy loam, but the percentage of silt is noticeably higher in some places. A few small areas that have a loam texture are included. -The 10- or 12-inch surface layer consists of light brownish-g-ay • to very pale-broom ver-,~ fine sandy loam. In some places the under- lying thir, depositional layers vary only slightly in color or texture. In other x:laces, especially near drainage courses, the layers are more caris_ble and may grade to loam, silt loam, or fine sandy loam. Af,evertheless, ~ yers of very fine sandy loam are more numerous. Below depths of 4 to 5 feet, the texture is sandier, and at depths of 8 to I2 feet strata of loamy fine sand, gravel, and scattered sandstone rock are common. Disseminated lima occurs from the surface downward. Owing to the friable consistence of the successive layers, the tilth, internal drainage, available supply of moisture for plants, permeability to plant roots, and other physical properties are favorable and assure a wide suitability range for crops. The organic-Natter content, however, is low. The soil is slightly saline under native cover and hc.s a few strongly saline spots. Occasionally the water table is high. 2Jo severe limitations exist for this soil type. • This soil type is considered to be within the Prime Agricultural Lands definition.
