Soil temperature: 48 to 56 degrees F.
Depth to free carbonates: 11 to 30 inches.
Depth to bedrock: 20 to 40 inches
Other features: Bk horizons are not present in some pedons.

Calcium carbonate equivalent: 2 to 15 percent. Some pedons have greater than 15 percent calcium carbonate equivalent, but the average is less than 15 percent in the majority of pedons.
Bk horizon (where present) - Hue: 7.5YR to 2.5YR. Value: 6 to 8 dry, 5 to 8 moist.

COMPETING SERIES: These are the Balon (AZ), Bowbac (WY), Buckle (NM), Cambria (WY), Cushman (WY), Decolney (T WY), Fattig (MT), Forkwood (WY), Gaddes (AZ), Gapbutte (T AZ), Gapmesa (T CO), Harbord (CO), Maysdorf (WY), Oelop (NM), Palacid (NM), Penistaja (NM), Pokeman (WY), Potts (WY), Pugsley (WY), Quagwa (AZ), Spangler (WY), Spenlo (UT), Sundance (CO), Tekla (T WY), and the Yenlo (CO) soils. The Balon, Buckle, Cambria, Decolney, Harbord, Maysdorf, Oelop, Palacid, Penistaja, Potts, Quagwa, Spenlo, Sundance, Teckla, and Yenlo soils are more than 40 inches to a lithic or paralithic contact. Bowbac, Cushman, Gaddes, Pokeman, Pugsley, and Spangler soils have a paralithic contact at depths at depths between 20 and 40 inches. Fattig soils have hues of 10YR or yellower in the argillic horizon. Gapbutte soils are effervescent to the surface. Gapmesa soils are effervescent to the surface.
GEOGRAPHIC SETTING: Hagerman soils are on hills, piedmonts, fans, ridgetops and mesas. The most common slopes are 0 to 8 percent but some range to 20 percent. Mean annual precipitation ranges from 10 to 13 inches, and mean annual temperature ranges from 46 to 54 degrees F. The average summer temperature is 67 degrees F. Most of the precipitation falls during the period from July through September. Frost-free period is 120 to 170 days and elevation ranges from 5,500 to 7,500 feet
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bernal, Dean and Skyvillage soils. Bernal and Dean soils have mollic epipedons. Skyvillage soils have bedrock within 20 inches of the surface.
DRAINAGE AND PERMEABILITY: Well drained. Permeability of the soil is moderate over a very slowly permeable bedrock. Runoff is negligible on slopes less than 1 percent, low on 1 to 3 percent slopes, medium on 3 to 5 percent slopes, high on 5 to 8 percent slopes, and very high on slopes greater than 8 percent.
USE AND VEGETATION: Dominant use is for range. Vegetation is blue grama, galleta, sand dropseed, snakeweed, cactus, and some pinyon and juniper.
DISTRIBUTION AND EXTENT: Central New Mexico, central and western Colorado. The series is extensive.
