<br />PUEBLO AREA, COLORADO
<br />The tvater• table is at a depth of 1.5 to 3 feet. The sur-
<br />face layer is law to Nigh in content of salts.
<br />The native vegetation is inland saltgrass, alkali
<br />sacatmi, tamarisk, and willow. Capability units IIhv-2,
<br />irrigated, and VIw-1, nonirrigated; Salt Meadow
<br />range site.
<br />Limon Set•ies
<br />Tho Limon series consists of deep, well-drained soils.
<br />These soils formed on alluvial fans and terraces in
<br />clayey alluvium. The slope is 0 to 5 percent, and eleva-
<br />tion is 4,300 to 5,100 feet. The average annual precipi-
<br />tation is 12 inches. The average annual temperature is
<br />53°F, and the frost-free seasmr is 145 to 175 claps. The
<br />native vegetation is mainly plains gs.asses.
<br />In a representative profile the surface la}'er is gray-
<br />ish-brown silty clay loam about 4 inches thick. The sub-
<br />surface layer is light brownish-gray' silty clay about
<br />14 inches thick. The underlying material is light
<br />brownish-gray silty cla}' about 17 inches thick over
<br />hgllt bl'Orvnlsh-gl'a}' silty clay loam that extends to a
<br />depth of 60 inches or more.
<br />Permeability is slow, and the available water ca-
<br />pacity is high. The surface and subsurface layers arc
<br />moderately alkaline an[1 the underlying material is
<br />moderately alkaline or strongly alkaline. The root zone
<br />extends to a depth of more than 60 inches. These soils
<br />arc used for grazing and irrigated crops.
<br />Representative profile of Limon silt}' clay- loam, 0 to
<br />2 percent slopes, in grass, 2.5 miles west and 0.2 mile
<br />north of the southeast corner of sec. 3G, T. 25 S., R.

<br />AC-4 to 15 inches, light brownish-gray (2.ST G/2) silty
<br />clay, dark grayish brown (2.5 ]' 9/2) .vhen moist; weak,
<br />medium and fine, subangular blocky structure; hard,

<br />Cl-1S to 35 inches, light brownish-gray (2.5]- 6/2) silty
<br />clay, dart: grayish brown (2.SY 9/2) when moist; weak,
<br />fine and very fine, subangular blocky structure; hard,
<br />firm; sticky and plastic; calcareous; fine filaments and
<br />thready, tr)'stallinc gypsum; moderately alkaline;
<br />gradual, smooth boundary.
<br />C2-35 to GO inches, light brownish-gray (2.5Y 6/2) silty
<br />clay loam, dark grayish brown (2.SY J/2) when moist;
<br />massive; slightly' hard, friable; sticky and plastic;
<br />strongly calcareous; moderate'.y alkaline.
<br />These soils range from moderately alkaline to strongly
<br />alkaline. They range from clay' to silty clay' loam. The AC
<br />and C horizons have weak blocky and weak platy structure
<br />or are massive.
<br />LnA-Limon silly clay loam, 0 to 2 percent slopes.
<br />This soil is on alluvial fans and terraces in the north-
<br />central and southeastern parts of the survey area. The
<br />areas cover- as much as 1,000 acres. This soil has the
<br />profile described as representative of the series.
<br />Included with this soil in mapping are areas of Razor
<br />soils that make rip about 5 percent of the acreage.
<br />Runoff is medium. The hazard of erosion is generally
<br />moderate, but it is severe in places. Deep gullying and
<br />soil piping are hazards where the range is overgrazed.

<br />The soil generally is not subject to flooding, but long,
<br />narrow, near•]y level areas along Dry Creek, Haynes
<br />Creek, and Kramer Creek and similar areas are subject
<br />to frequent, brief flooding.
<br />This soil is difficult to till because it is cloddy when
<br />dry and sticky and plastic when wet. The native grasses
<br />are mainly galleta, blue grams, and alkali sacaton. Capa-
<br />bility units IIe-1, irrigated, and VIe-2, nouin'igated;
<br />Salt Flats range site.
<br />Ln13-Limon silty clay loam, 2 to 5 percent slopes.
<br />This sail is in long, narrow areas between the Arkansas
<br />River and Fountain Creek. The areas cover as much
<br />as 300 acres. This soil has a profile similar to the mle
<br />described as representative of the series.
<br />Included with this soil in mapping are areas of Razor
<br />soils that make up about 20 percent of the acreage.
<br />Runoff is rapid, and the hazard of erosion is high.
<br />The native grasses are mainly alkali sacaton, blue
<br />grams, and galleta. Capability writs IIIe-2, irrigated,
<br />ansl VIe-2, nonirrigated; Salt Flats range site.
<br />LoA-Limmr silty clay, 0 l0 2 percent slopes. Thi=
<br />soil is on alluvial fans and terraces in the north-central
<br />and southwestern parts of the survey area. 1'he area=
<br />cover as much as 800 acres..This soil has a profile
<br />similar to the one described as representative of the
<br />series, but the surface layer is silty clay and the under-
<br />lying material is strmrglp alkaline. About 15 percent
<br />of the surface area is cocere[l by barren slickspots.
<br />Included with this soil in mapping are areas of
<br />Apishapa an[I Haverson soils that make up about 1(
<br />percent each of the acreage.
<br />Runoff is slow, and the hazard of erosimr is moderate
<br />This soil is difficult to till because it is sticky ans
<br />plastic when wet. The native vegetatimr is mainly
<br />alkali sacaton, blue grams, galleta, and greasen'ood
<br />Capability units II[s-1, irrigated, and VIe-2, nonirri
<br />gated; Salt Flats range site.
<br />LvB-Limon silly clay', 0 to 5 percent slopes, gullied
<br />This soil is in the central part of the survey area. 1'hs
<br />areas are irregularly shaped and cover as much as 60(
<br />acres. This soil has a profile similar to the one describes
<br />as representative of the series, but the surface layer i~
<br />silty clay and the areas are dissected by gullies than
<br />are 2 to 10 feet deep.
<br />Included with this soil in mapping are areas of Rlid
<br />way soils and Shale outcrop that make up about 1t
<br />percent of the acreage.
<br />Runoff is rapid, and the hazard of erosion is high.
<br />Range seeding is difficult because of the deep gullies
<br />Capability unit VIIe-1, nonirrigated; not in a rang
<br />site.
<br />11'Ianvel Series
<br />The i1lam'el series consists of deep, well-drained soils
<br />These soils formed on alluvial fans in silty colluvial an
<br />alluvial material that weathered mainly from limestone
<br />The slope is 0 to 5 percent, and elevation is 4,400 t
<br />5,800 feet. The average annual precipitation is 1
<br />inches. The average annual temperature is 53° F, an
<br />the frost-fr'ee season is 145 to 175 days. The nativ
<br />vegetation is mainly plains grasses.
