Where not cultivated the vegetation is chiefly annual and perennial grasses, forbs, shrubs, wild berry vines, and scattered oak trees. Generally, this soil is more stratified than Yolo loam, 0 to 2 % slopes. The silt loam surface layer is a result of deposition from infrequent overflow and the sloughing of finer-textured soil material from areas bordering this soil. Included in mapping are small areas of Cortina very gravelly sandy loam, Pajaro gravelly loam, Pleasanton loam and Zamora silty clay.The available water capacity is 10 to 12 inches.

Grangeville fine sandy loam,0 to 1% slopes.

Row crops are grown on this soil.The soils of the Grangeville series occupy nearly level, low parts of recent alluvial fans and flood plains. The parent material was derived from granitic and other micaceous rocks. Under natural conditions these soils were imperfectly drained and subject to flooding and a periodic high water table, but as a result of pumping, those in this Area are now mostly well drained. The Grangeville soils are similar to Hanford soils, but are darker colored, contain lime, and are mottled chiefly in the subsoil and substratum. Under natural conditions, they are somewhat better drained than the Foster soils, but they are not so high in organic matter, nor so dark colored, nor do they contain so much lime. Runoff is very slow, and internal drainage is moderately rapid. The root zone is very deep, and the water-holding capacity and natural fertility are moderate. The erosion hazard is slight, and there are no excess salts or allkali. Vegetable production.

Visalia sandy loam,0 to 3% slopes.

The soils of the Visalia series occupy swalelike and other nearby level positions on low, recent alluvial fans and flood plains. These soils were derived from sediments washed from granitic and other micaceous rocks. Under natural conditions they were imperfectly drained and subject to flooding and a periodic high water table, but, as a result of pumping these Areas are now mostly moderately well drained. Except for variations resulting from stratification, the profiles are moderately coarse textured and dark colored to considerable depths. These soils are similar to the Grangeville soils but have little or no mottling in the subsoil and substratum and are typically lime free throughout. This soil is slightly lower in moisture-holding capacity and natural fertility than Visalia fine sandy loam, 0 to 1% slopes, but is otherwise similar to it. Internal drainage is rapid. To compensate for its lower water-holding capacity and natural fertility, this soil needs lighter and more frequent irrigation than Visalia fine sandy loam, 0 to 1% slopes, and somewhat more fertilizer.

Myoma soils are nearly level to rolling, have hummocky micro relief where unprotected and are at elevations of 200 feet below sea level to 1,800 feet above sea level. The soil formed in sand blown from recent alluvium. The climate is arid with an annual precipitation of 2 to 4 inches that occurs as gentle winter rain or erratic high intensity summer storms. The average January temperature is about 53 degrees F., average July temperature is 92 degrees F. and the average annual temperature is about 72 to 75 degrees F. The frost-free season (32 degrees F.+) is about 290 days. Myoma soils are used principally for growing citrus fruits, grapes, alfalfa, dates and truck crops under irrigation.

This soil consists of 30 inches to 6 feet of reddish-brown sandy loam, frequently containing fine waterworn gravel. Where the sandy loam is less than 6 feet in depth it is underlain by a dark-brown sticky loam. Hardpan does not occur in this soil, excepting in a few places west

of Sutter, where a gray calareous hardpan is found at or below 48 inches. This type is not an extensive one, occuring as small scattered bodies running to the north and sout from Live Oak. A small body is also found in Yuba County north of the Yuba river The surface varies from level to slightly rolling. The elevation is usually a little higher than that of surrounding soils. The drainage is good. The body of this soil is of sedimentary origin, but it has been largely reworked by later alluvial agencies.

Atwater sandy loam, 0 to 3 percent slopes.

The Atwater series

This series consists of deep, well-drained, coarse textured and moderately coarse textured soil that formed in stabilized old dunes of wind-sorted material. This material was blown from dry, sandy streambeds or other areas of sandy, granitic alluvium. Under natural conditions the soils are undulating to rolling. Areas of these soils lie in a northwest-southeast position, parallel to the prevailing wind direction. They are commonly located on the lee side of stream channels that flow southwesterly, such as those of Fancher Creek and Dry Creek near Clovis, Fresno and Sanger. The soils range in elevation from about 250 to 450 feet. The average annual precipitation ranges with elevation from 9 to 14 inches. The average annual temperature is about 62 degrees F. The growing season ranges from about 250 to 275 days. Natural vegetation consists of annual grasses and forbs. Typically Atwater soils have a light brownish-gray to dark grayish-brown loamy sand surface layer about 24 inches thick. The subsoil is brown sandy loam about 19 inches thick. Atwater sandy loam has a soil profile similar to that described for the series except that it has a sandy loam surface layer. It is gently undulating. In outline, it shows a strong tendency toward a lobed pattern extended in the direction of the prevailing winds, or it lies in the position of a longtudinal dune on the lee side of the sandy streamway. The available moisture holding capacity ranges from low to moderate, the hazard of soil blowing is less severe than the Atwater loamy sands. Runoff is slow and erosion from moving water is negligible. Row crops grown in this soil.

HoD, Holland sandy loam, 30 to 45 percent slopes.

The soils of the Holland series developed from residuum weathered from coarse-grained grained granitic rocks. They occupy the more strongly sloping higher foothill sand lower mountains. In this area they are generallyat altitudes of 2,800 to 3,500 feet or more. The annual precipitation ranges from about 25 to 40 inches; some ofit is snow.

CyA, Corralitos sandy loam, over clay, nearly level, imperfectly drained.

This soil is similar to Corralitos sandy loam, nearly level, imperfectly drained, except that it is underlain at a depth of 10 to 36 inches by clay over which the more recent Corralitos sandy loam material has been deposited. Slope ranges from 0 to 1 percent. Water disposal is a problem on this soil; the water table is within 5 feet of the surface much of the time, and it often affects crops and management practices. Permeability in the clay is slow. The effective depth of root penetration is shallow to moderately deep. There is a slight erosion hazard and also some risk of stream-bank cutting. The soil is fairly easy to work. If it is managed properly to control the water table and to overcome the surface droughtiness, fair to high yields of truck crops can be expected. Mixed vegetable production. Chard
