Introduction

South Dakota has many different kinds of soils.To keep the characteristics and qualities of thesesoils in mind, grouping them systematically intoa classification scheme is necessary. The classifi-cation of soils: (1) aids in remembering characteristics of

individual soils, (2) clarifies relationships between soils, (3) aids in discovering new facts, (4) clarifies relationships between soils and

their environment, and (5) aids in a person's ability to predict properties

of unknown soil based on similar, known soils.

Soil classification

The system of soil classification adopted in theUnited States is called Soil Taxonomy (SoilSurvey Staff, 1999). Soil Taxonomy has replacedthe 1938 Yearbook System of Soil Classification(Baldwin, Kellogg, and Thorp, 1938; Kellogg,1941).

To assist in using the current system, a list ofapproximate 1938 equivalents for South DakotaSoils is presented in Table 1. The soils of SouthDakota as recognized by the USDA-NRCS (SoilSurvey Staff, 2003) have been classified based onSoil Taxonomy (Appendix). There are six cate-gories in Soil Taxonomy and they are (in decreas-ing rank or increasing number): order, suborder,great group, subgroup, family, and series. Usingthis information a classification key has beenprepared (Table 2).

The highest category of the soil classificationsystem is order. Orders differentiate soils by thepresence or absence of diagnostic horizons or

features that are characteristic of the kinds andintensities of soil forming processes and con-trasting climates. All soils fit into one of 12 soilorders. In South Dakota six soil orders are pres-ent (Table 3).

Suborders within a soil order are differentiatedon the basis of important soil properties thatinfluence genesis and plant growth. There are atleast 64 suborders presently recognized with 23in South Dakota. The large number of subordersis a result of differences in soil moisture, soiltemperature, climatic and vegetative influenceson soil genesis, and mineralogy.

At the great group level the entire soil profile, thehorizonation present, and the most significantfeatures of the entire profile are considered. Soilgreat groups are subdivisions of suborders andthere are at least 315 great groups currently rec-ognized (Soil Survey Staff, 1999); 54 are found inSouth Dakota. The great group category com-bines soils that have close profile similarities inthe kinds of horizons, the arrangement of hori-zons, the degree of expression of horizons, soilmoisture regimes, soil temperature regimes,base saturation status, calcium content, iron con-tent, gypsum content, and other salt content.

Each great group is divided into three kinds ofsubgroups. These are: (1) the central concept ofthe great group (Typic); (2) soil properties whichintergrade to or are transitional toward otherorders, suborders, or great groups; and (3) sub-groups with properties that are not representa-tive of any other order, suborder, or great group(extragrades). There are at least 2,450 knownsubgroups with 158 in South Dakota.

Soil Classification Key for South Dakota Soils1

This key is an adaptation from and an expanded revision of Soil Classification Key forSouth Dakota Soils, TB 96, 1994, and contains revised material from Soils of South Dakota, Bulletin 656, 1978.2 Distinguished Professor, Plant Science Department, South Dakota State University, Brookings 57007-2141.

The next lower category is the soil family. Soilfamilies are separated within a subgroup on thebasis of similar physical and chemical propertiesthat influence plant growth, land managementdecisions, and engineering purposes. Soil prop-erties such as texture, mineralogy, soil reaction,soil temperature regime, thickness of soil pene-trable by roots, thickness of horizons, and thearea's precipitation pattern are used as criteriato differentiate soil families. In the United States,at least 7,000 soil families are recognized, with432 in South Dakota.

At the lowest level is the soil series. Soil seriescontain the least variation in soil properties whilesoil orders contain the most. The soils includedin an individual soil series are nearly homoge-neous, their range of properties is limited, andthey have similar interpretations. Soil series areseparated and rated on the basis of observableand mappable soil properties such as color,texture, structure, horizon arrangement andthickness, mineralogy, moisture and temperatureregimes, consistence, and horizon presence andexpression. There are at least 19,000 establishedand tentative soil series recognized in the UnitedStates with 610 in South Dakota. In addition,there are 16 inactive (not currently used in fieldmapping) soil series in South Dakota.

The higher the category (e.g., order and subor-der) of classification, the fewer precise state-ments that can be made for the unit. For mostfarm management work, the soil series is themost useful unit. However, the higher categorieshave use in helping to clarify regional relation-ships among soils.

Soil classification nomenclature

The nomenclature used to classify soils (see soilclassification key, Table 2) is not familiar to mostusers of soils information. As a result, definitionsof the various terms used in South Dakota foreach classification category are presented (Tables4-11). Each part (syllable) of the soil classificationname describes a soil property or genesis con-cept (see example for the Houdek soil, next).

Soil survey status in South Dakota

The status of soil surveys in South Dakota isshown in Figure 1. Figure 2 shows the status ofdigitization of soil survey maps. All counties inthe state have either a published survey or haveactivities planned to complete and publish asurvey.

Summary

This publication presents a soil classification keyfor soils found in South Dakota. Descriptions ofthe meanings of the various soil classificationterms and an alphabetical listing of the SouthDakota soil series are also presented (Appendix).

Table 4. Soil orders found in South Dakota: the names and their meanings.*______________________________________________________________________________

Order FormativeName Element Principal Diagnostic Property(ies) - Definition______________________________________________________________________________________________

Alfisols alf Mineral soils; relatively low in organic matter; relatively high basesaturation (>35%); an illuvial horizon of silicate clays (argillic [Bt] or natric[Btn]); moisture available to mature a crop; soils of temperate regionforests with moderate effects of weathering and leaching; soils areslightly to moderately acid.

Aridisols id Mineral soils; relatively low in organic matter; inadequate moisture tomature a crop without irrigation in most years; some pedogenic horizons(e.g., horizons of lime [Bk], gypsum [By], salt [Bz] or clay [Bt]accumulation).

Entisols ent Mineral soils; weak or no pedogenic horizons, no deep, wide cracks inmost years; limited profile development (weak A horizons only, nodiagnostic B or A horizons other than ochric); soils of recent origin.

Inceptisols ept Mineral soils; some pedogenic (salt accumulations [e.g., Bk, By, or Bzhorizons] or color development [e.g., Bw or Bg]) horizons and someweatherable minerals; moisture available to mature a crop in most years;no horizon of illuvial clays; relatively low in either organic matter or basesaturation, or in both; more development than Entisols but less than otherorders (except for some Aridisols).

Mollisols oll Mineral soils, thick dark surface horizon, relatively rich in organic matter;organic matter is due to soil genesis and not sedimentation; high basesaturation throughout; no deep wide cracks in most years; friable; soils ofsubhumid to semiarid grasslands; often have horizons of limeaccumulation (e.g., Bk) within the profile.

Vertisols ert Clayey soils; deep, wide cracks at some time in most years; self mixingsoils; soils high in expanding clay (smectitic mineralogy); have distinct wetand dry seasons each year. Slickensides are evident in the B horizons(e.g., Bss).

loamy-skeletal Rock fragments make up at least 35% by volume; enough fine earth to fillinterstices >1 mm; and the fraction <2 mm is loamy (<35% clay) as defined forthe loamy particle-size class.

clayey-skeletal Rock fragments make up at least 35% by volume; enough fine earth to fillinterstices >1 mm; and the fraction <2 mm is clayey as defined for the clayeyparticle-size class.

sandy The texture of the fine earth is sand or loamy sand that contains <50% byweight very fine sand and rock fragments make up <35% by volume.

loamy1 The texture of the fine earth is loamy very fine sand, very fine sand, or finer,but the amount of clay is <35% by weight (excludes Vertisols); rock fragmentsare <35% by volume; and soils are in a shallow family or a strongly contrastingparticle-size class.

a. coarse-loamy By weight, 15% or more of the particles are fine sand (diameter 0.25 to0.1 mm) or coarser, including fragments up to 7.5 cm in diameter; and<18% (by weight) in the fine-earth fraction.

b. fine-loamy By weight, 15% or more of the particles are fine sand (diameter 0.25 to0.1 mm) or coarser, including fragments up to 7.5 cm in diameter; and18 to 34% clay in the fine-earth fraction (Vertisols are excluded).

c. coarse-silty By weight, <15% of the particles are fine sand (diameter 0.25 to 0.1mm) or coarser, including fragments up to 7.5 cm in diameter; and<18% clay by weight in the fine-earth fraction.

d. fine-silty By weight, <15% of the particles are fine sand (0.25 to 0.1 mm dia.) orcoarser, including fragments up to 7.5 cm in diameter; and 18 to 34%clay (weight) in the fine-earth fraction (Vertisols are excluded).

clayey1 The fine earth contains at least 35% clay by weight (30% in Vertisols); rockfragments are <35% by volume; and soils are in a shallow family or a stronglycontrasting particle-size class.

a. fine A clayey particle-size class for soils having 35 to 59% clay in the fine-earth fraction (30 to 59% clay for Vertisols).

b. very-fine A clayey particle-size class for soils having at least 60% clay in the fine-earth fraction.

1 If the ratio of 1500 kPa water retention to clay is 0.6 or more in half or more of the control section, the percentage of clay is considered to be2.5 (% water retained at 1500 kPa - % organic carbon). Carbonates of clay size are not considered to be clay but are treated as silt in allparticle-size classes.*Soil Survey Staff, 1999.

acid The pH is less than 5.0 in 0.01 M CaCl2 (2:1) throughout the control section(about 5.5 in H2O, 1:1).

active Ratio of cation exchange capacity to clay percent is 0.40 to 0.59.

calcareous The fine earth fraction effervesces in all parts (depth of 25 to 50 cm orshallower if lithic or paralithic contact is present) with cold dilute HCl.

carbonatic More than 40% by weight (whole soil) carbonates plus gypsum and thecarbonates are more than gypsum.

gypsic More than 40% by weight (whole soil) of carbonates plus gypsum, and thegypsum is more than 35% of the total sum of carbonates and gypsum.

paramicaceous More than 25% mica and stable mica pseudomorphs by weight (65% bygrain count) in the coarse silt to gravel fractions (0.02 to 20 mm).

mixed Soils which have less than 40% of any one mineral other than quartz orfeldspars in the coarse silt and sand fractions (0.02 to 20 mm).

semiactive Ratio of cation exchange capacity to clay percent is 0.24 to 0.39.

smectitic Have more smectite (e.g., montmorillonite and nontronite) by weight thanany other single kind of clay mineral.
