It is intermittently moist in some part November through April. The period of maximum precipitation is July through September. The soil is driest during May and June. Ustic aridic moisture regime.
Soil temperature: 51 to 56 degrees F.
Depth to calcium carbonate: 8 to 23 inches

Chroma: 4 to 6 dry and moist
Reaction: neutral or slightly alkaline
Bt horizon:
Hue: 7.5YR or 10YR
Value: 4 or 5 dry; 3 to 5 moist
Chroma: 4 to 6 dry; 3 to 6 moist

Btk and Bk horizon:
Hue: 7.5YR or 10YR
Value: 5 or 7 dry; 4 to 6 moist
Chroma: 3 to 6 dry and moist
Texture: sandy clay loam, sandy loam, or clay loam

COMPETING SERIES: These are the Balon (AZ), Blancot (NM), Bowbac (WY), Buckle (NM), Cambria (WY), Chilerojo (NM), Cushman (WY), Decolney (WY), Doakum (NM), Forkwood (WY), Fort (CO), Gaddes (AZ), Gapbutte (AZ), Gapmesa (CO), Hagerman (NM), Hiland (WY), Mentmore (NM), Oelop (NM), Olney (CO), Palacid (NM), Penistaja (NM), Pokeman (WY), Potts (WY), Pugsley (WY), Quagwa (AZ), Redpen (NM), Spangler (WY), Sundance (CO), Tamarindo (NM), Teckla (WY) and Yenlo (CO) series. Balon, Blancot, Buckle, Cambria, Decolney, Doakum, Forkwood, Fort, Mentmore, Oelop, Olney, Palacid, Penistaja, Potts, Quagwa, Redpen, Spenlo, Sundance, and Teckla soils are more than 40 inches to a lithic or paralithic contact. Bowbac, Cushman, Pokeman, Pugsley, and Spangler series are moderately deep to a paralithic contact. Gapbutte and Pawspoc soils are moderately deep to basalt bedrock. Gapmesa soils have mean annual air temperatures below 49 degrees F. Hagerman soils typically have redder hues, darker surface horizons with higher organic carbon, and have moisture patterns which receive slightly more precipitation during late spring and early summer. Los Alamos soils have pumice and ash in the control section. In addition Bowbac, Cushman, Decolney, Fort, Forkwood, Olney, Pokeman, Potts, Pugsley, Spangler, Sundance, and Teckla soils are in LRR-G and are more moist in May and June.
GEOGRAPHIC SETTING: The Hagerwest soils formed in eolian material, slope alluvium and alluvium. Hagerwest soils are on hills, ridges, cuestas, and mesas. Slopes range from 0 to 5 percent. Mean annual precipitation ranges from 10 to 13 inches and mean annual temperature ranges from 49 to 54 degrees F. Most of the precipitation falls during the period from July through September. Frost-free period is 120 to 140 days and elevation ranges from 6,500 to 7,200 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bond, Penistaja, and Sparank soils. The Bond soils are medium textured, shallow, and on dipslopes of cuestas. The Penistaja soils are medium textured, very deep, and on fan remnants. The Sparank soils are fine textured, very deep, and on flood plains.
DRAINAGE AND PERMEABILITY: Well drained. Permeability of the soil is moderate over very slowly permeable bedrock. Runoff is negligible on slopes less than 1 percent and low to medium on 1 to 5 percent slopes.
USE AND VEGETATION: This series is used for range and wildlife habitat. Vegetation is blue grama, galleta, sand dropseed, snakeweed, prickly pear, oneseed juniper, and twoneedle pinyon.
DISTRIBUTION AND EXTENT: West central New Mexico. LRR-D, MLRA 35. The series is of limited extent.
