<br /> Range of Characteristics: Barx was described at 12 locations within the study area (profile description numbers # 1, 6, 7, 10, 11, 12, 18, 24, 25, 26, 58,
<br /> anDepth to bedrock is greater than 40 inches, and averaged more than 67 inches across the study area. The solum is 20 to 40 inches thick although
<br /> with the inclusion of the Bk calcic horizon it can be thicker. The Bk calcic horizon is at a depth ranging from 16 to 54 inches. The profile has 0 to 15
<br /> percent rock fragments. If unplowed, the surface horizon is usually leached of carbonates. The Bt particle-size control section has 18 to 34 percent
<br /> clay. Profile hue is 10YR, 7.5YR, 5YR, 2.5YR or 2.5Y. The A horizon has value of 4 to 6 dry, and chromas of 3 to 6. It is neutral through moderately
<br /> alkaline. The Bt and Btk horizons have value of 3 to 7.5 dry and moist and chroma of 3 to 6. Textures are dominately sandy clay loam or loam. Reaction
<br /> is mildly to moderately alkaline and is noncalcareous to strongly calcareous in the Bt argillic horizon and is strongly to very strongly calcareous in the
<br /> Bk calcic horizon. Calcium carbonate equivalent in the calcic horizon is 15 to 37 percent. The C horizon substratum has a hue of 7.5YR, 5YR, or 2.5Y,
<br /> value of 4 to 6 dry and moist, and chroma of 2 to 6. Textures are dominantly sandy clay loam or sandy loam. Reaction is mildly to moderately alkaline
<br /> and is strongly to very strongly calcareous. Sample sites #7, 26, and 58 were in irrigated fields, whereas #10 was located in a vPr� old orchard and,
<br /> Ca. according to the landowner, had not ever been plowed. As a result, sample site #10 more closely approximates the native Barx soil ++r.+ +-,rhed by plowing
<br /> 0 or other surface disturbance. Associated vegetation at the sample site #7 consists of irrigated crops, at #26 and 58 irrigated hay 9t , —es, and at #10 of
<br /> SO orchard trees and native grasses.
