<br />sandy and do not have a 82t horizon. Haverson soils
<br />have a color value of 4 or more when moist and do not

<br />In some pedons thin strata of sand are in one or more
<br />horizons. in some pedons the soil is as much as 10
<br />percent gravel. The depth to lime ranges from 20 to 40
<br />inches. The mollic epipedon is 20 to 40 inches thick. The
<br />A horizon is neutral or mildly alkaline.
<br />The B2t horizon ranges from clay loam to sandy clay
<br />loam. The C horizon ranges from loam to fine sandy
<br />loam.
<br />Ascalon series
<br />The Ascalon series consists of deep, well drained soils
<br />that formed in moderately coarse textured, wind-
<br />reworked, calcareous alluvium of the Ogallala formation.
<br />Ascalon soils are on smooth plains. Slopes range from 0
<br />to 9 percent. The mean annual precipitation is 17 inches,
<br />and the mean annual temperature is 51 degrees F.
<br />Ascalon soils are near Platner, Manter, Julesburg, and
<br />Haxtun soils. Platner soils have a clayey B2t horizon.
<br />Julesburg and Manter soils have a sandy loam 82t
<br />horizon. Haxtun soils have a buried horizon within a
<br />depth of 40 inches.
<br />Typical pedon of Ascalon fine sandy loam, 0 to 3
<br />percent slopes, in a cultivated field 10 miles north and 5
<br />miles east of Yuma, 550 feet east and 100 feet south of
<br />the northwest corner of sec. 3, T. 3 N., R. 47 W.

<br />fine sand, yellowish brown (10YR 5/4) moist;
<br />massive; very hard, very friable, nonsticky and
<br />nonelastic; violently effervescent; moderately
<br />alkaline.
<br />The mollic epipedon is 7 to 20 inches thick. Typically,
<br />the depth to lime is 15 to 20 inches, but it ranges from
<br />15 to 30 inches. In some pedons, the soil is as much as
<br />15 percent gravel.
<br />The A horizon ranges from fine sandy loam to loamy
<br />sand. It is neutral to mildly alkaline.
<br />The B horizon is 12 to 24 inches thick. The B2 horizon
<br />is neutral or mildly alkaline.
<br />The C horizon ranges from fine sandy loam to loamy
<br />sand. it is moderatey alkaline or strongly alkaline.
<br />Bankard series
<br />The Bankard series consists of deep, somewhat
<br />excessively drained soils that formed in stratffied sandy
<br />alluvium. Bankard soils are on flood plains and second-
<br />bottom terraces along intermittent and perennial
<br />streams. Slopes are 0 to 2 percent. The mean annual
<br />precipitation is 17 inches, and the mean annual
<br />temperature is 51 degrees F.
<br />Bankard soils are near Gienberg, Haverson, Platte,
<br />and Las Animas soils. Gienberg soils are stratified fine
<br />sandy loams. Haverson soils are stratified loam, silt
