BACA COUNTY,
<br />•
<br />Gosh loan, 1 to 3 percent slopes (GoB). —This soil
<br />occurs as small areas on tho side slopes of drainageways
<br />in the northeastern quarter of the county. The surface
<br />layer is loam or light clay loam about 4 to 12 inches
<br />thick. The subsoil, about 14 inches thick, is silt loam
<br />or clay loam. Limo occurs at a depth of 15 to 30 inches.
<br />Included in mapping were small areas of Wiley loam
<br />and Baca clay loam.
<br />This soil has moderate water intake. Surface runoff
<br />is medium.
<br />Most of the acreage is cultivated. Wheat and sorghum
<br />are the main crops. Land leveling is necessary for uni-
<br />form application of water. During periods of drought,
<br />deep listing and chiseling aro needed. Stubble mulching
<br />ai striperopping help control soil blowing. On range,
<br />proper management practices such as deferred and ro-
<br />tation grazing are necessary for maintaining and im-
<br />liroving the vegetative cover. (Capability unit IIe - 1,
<br />irrigat.cd, and capability unit IIIc -1, nonirrigated;
<br />Loamy Plains range site; Loamy windbreak suitability
<br />group)
<br />Gravelly Land
<br />Gravelly land (3 to 20 percent slopes) (Gr) borders
<br />the major drainageways. It consists of excessively
<br />drained, relatively thin, gently sloping to moderately
<br />steep soils on uplands.
<br />The surface layer of this land type is light - colored
<br />gravelly loam in most places, but small areas of sandy
<br />loam are common. The subsoil ranges from gravelly loam
<br />to light clay loam.
<br />Gravelly land has moderately rapid to rapid surface
<br />runoff, moderate permeability, and low available water
<br />capacity.
<br />All of the acreage is in native vegetation that consists
<br />mainly of side -oats grania, blue grams, buffalograss, and
<br />yucca. (Capability unit VIIs -2, nonirrigated; Gravel
<br />Breaks range situ)
<br />Harbord Series
<br />The Harbord series consists of deep, nearly level to
<br />gently sloping, light- colored loams on uplands.
<br />In a typical profile the surface layer, about 3 inches
<br />thick, is brown, very strongly calcareous loam. The sub-
<br />soil is brown, noncalcareous silty clay loam about 13
<br />inches thick that rests on an older buried soil about 13
<br />inches thick. The buried soil is clay loam and contains
<br />many white lime streaks and mottles. Below a depth of
<br />about, 20 inches is pink, very strongly calcareous clay
<br />loam.
<br />Harborer soils are naturally well drained. They have
<br />moderato to slow water intake, high available water
<br />capacity, and high natural fertility.
<br />Most of the acreage is cultivated. Wheat cold sorghum
<br />are, die main arms,. \•tnch of Clio acrcn.go is ilryfariii 1,
<br />but some of it is irrigated. Whore in native grass, blue
<br />grama. and bu(falograss aro the principal grasses.

<br />Ap—O to 3 inches, brown (7.5YR 6/3) loam, dark brown

<br />strongly calcareous ; clear, smooth boundary.
<br />B21t -3 to 16 inches, brown (7.5YR 5/4) silty clay loam,
<br />dark brown (7.5YR 4/4) when moist; moderate,
<br />coarse, prismatic structure that parts to moderate,
<br />medium, subangular blocky ; hard when dry,
<br />firm when moist; thin, patchy clay skins; noncal-
<br />calcareous ; gradual, wavy boundary.
<br />B22cab -16 to 20 inches, light -brown (7.5YR 6/4) clay loam,
<br />dark brown (7.5YR 4/4) when moist; weak, me-
<br />dium, prismatic structure that parts to moderate,
<br />medium, subangular blocky ; hard when dry, firm
<br />when moist; thin, patchy clay skins; very strongly

<br />(7.5YR 7/4) when moist; massive; slightly hard •
<br />when dry, firm when moist; very strongly cal-

<br />The A horizon ranges from 2 to 6 inches in thickness
<br />and from loam to light clay loam in texture. The B2t hori-
<br />zon ranges from 6 to 20 inches in thickness and from silty
<br />clay loans to clay loam in texture. Depth to the buried soil
<br />ranges from 10 to 20 inches.
<br />Harbord loan, 0 to 1 percent slopes (HaA). — This soil
<br />occurs throughout the county.
<br />Included in mapping were small areas of Baca and
<br />Campo clay loam; small areas of Potter gravelly loam
<br />in the western half of the county; and, near Walsh,
<br />areas of Wiley loam.
<br />This soil absorbs water well. Surface runoff is slow, and
<br />available water capacity is high. Soil blowing is the
<br />-major hazard.
<br />About 70 percent of the acreage is cultivated. Wheat
<br />and sorghum are the main crops. Fertilizing, use of
<br />crop residue, and water management are necessary to
<br />improve production. Stubble mulching and striperopping
<br />help control soil blowing, and during periods of drought,
<br />deep listing and chiseling also help. Proper range man-
<br />agement is necessary. (Capability unit I -1, irrigated,
<br />and capability unit IVe -1, nonirrigated; Loamy Plains
<br />range site; Loamy windbreak suitability group)
<br />Harbord loan, 1 to 3 percent slopes (HaB).—This soil
<br />occurs throughout the county.
<br />Included in snapping were small areas of Baca clay
<br />loam and Harvey loam.
<br />This soil has medium surface runoff.
<br />About 70 percent of the acreage is cultivated. Winter
<br />wheat and sorghum are the main crops in both dryland
<br />and irrigated areas. Land leveling, fertilizing, use of crop
<br />residue, and water management aro necessary to improve
<br />. production. Stubble mulching and striperopping help
<br />control soil blowing, and during periods of drought, deep
<br />listing and chiseling also help. Proper range management
<br />is necessary. (Captiiility unit IIe -1, irrigated, and capa-
<br />bility unit IVe -1, nonirrigated; Loamy Plains range site;
<br />Loamy windbreak suitability group)
<br />Harbord loan, 3 to 5 percent slopes (HaC). — This soil
<br />occuis throughout the county. It has a profile similar to
<br />that described as typical for the series except that in
<br />ninny plains * the soil surface is moderately eroded.
<br />Included in mapping worn small areas of Wiley and
<br />Harvey loans, Baca clay loam, and Colby silt loan.
<br />W1 re there is adequate cover, 111110 IT is inodlium.
<br />1\�lu +ru cover is inadequate, runolt is rapid. Internal
<br />drainage is slow.
