HAVERSON SERIES
' The Haverson series consists of very deep,well drained soils that formed in alluvium from mixed
sources. Haverson soils are on floodplains and low terraces and have slopes of 0 to 9 percent. The
' mean annual precipitation is about 15 inches and the mean annual air temperature is about 52
degrees F.
' TAXONOMIC CLASS: Fine-loamy, mixed, superactive, calcareous, mesic Aridic Ustifluvents
TYPICAL PEDON: Haverson loam - grassland. (Colors are for dry soil unless otherwise noted)
1 Al--0 to 3 inches; pale brown (10YR 6/3) loam, dark brown (10YR 3/3) moist; strong fine granular
structure; slightly hard, very friable; violently effervescent; slightly alkaline (pH 7.8); clear smooth
' boundary. (2 to 6 inches thick)
A2-3 to 6 inches; pale brown(10YR 6/3)loam, dark brown (10YR 3/3) moist; weak fine and
' medium granular structure; hard, friable; strongly effervescent;slightly alkaline(pH 7.8); abrupt
smooth boundary. (2 to 6 inches thick)
' A3-6 to 12 inches; light brownish gray(IOYR 6/2) loam, dark grayish brown (IOYR 4/2)moist;
weak coarse subangular blocky structure; very hard, friable; strongly effervescent; slightly alkaline
(pH 7.8); clear smooth boundary. (4 to 8 inches thick)
' C1-12 to 32 inches; pale brown(10YR 6/3)very fine sandy loam that has thin strata of loam, brown
(10YR 4/3) moist; massive; hard, friable; strongly effervescent; slightly alkaline(pH 7.8); gradual
smooth boundary. (16 to 24 inches thick)
C2--32 to 60 inches; pale brown(10YR 6/3) loam that has thin lenses of sandy loam and very fine
' sandy loam, brown(10YR 4/3)moist; massive; slightly hard, very friable; few fine irregularly
shaped masses and seams of lime; strongly effervescent; moderately alkaline (pH 8.4)
TYPE LOCATION: Weld County, Colorado; approximately 1,320 feet south and 1,320 feet east of
the northwest comer of Sec. 36,T. 10 N., R 64 W.
RANGE IN CHARACTERISTICS: Mean annual soil temperature ranges from 47 to 55 degrees F.
and mean summer soil temperature ranges from 59 to 79..degrees F. Organic carbon ranges from 0.5
to 2.0 percent in the surface horizon but decreases irregularly with depth. The particle-size control
' section is stratified with strata ranging from sandy loam to clay loam, but averaging approximately
loam. On a weighted average basis,clay ranges from 18 to 35 percent, silt from 10 to 50 percent, and
sand from 20 to 60 percent with more than 15 percent but less than 35 percent being fine or coarser
' sand. Rock fragments are generally less that 5 percent and range from 0 to 20 percent. Some visible
calcium carbonate may occur at any depth in these soils, but it is not concentrated into any consistent
horizon of accumulation. This soil is not dry in all parts of the moisture control section for more than
