Soil Series of
Louisiana Arranged By Soil Area 28
Preface
The idea for this guide to the soils of Louisiana originated with Dr.
Bob Miller. Dr. Miller had prepared a brief guide to some of the major
soils of Louisiana for his soil pedology course. The guide consisted
of
tables of the major soils in Louisiana arranged by soil area and taxonomic
classification. Dr. Amacher thought that the guide should be expanded
to include all the soils mapped in Louisiana and should be published in
some form to reach a wider audience. Thus the idea for the current guide
was born. With the untimely death of Dr. Miller it fell to the coauthors
to complete the task. This guide is dedicated to Dr. Bob Miller whose
immense contributions to the study of Louisiana soils have made the job
of those who follow so much easier.

Introduction
This guide
to
the soils
of
Louisiana is intended to provide a list
of
the
soil series that have been mapped in the state along with basic information
about each series. The guide should prove useful to scientists and others
interested in soils, since the information is compiled and summarized in
a single source.
Table 1 is an alphabetical listing of the soil series that have been
mapped in the past or are currently being mapped in Louisiana, along
with the taxonomic classification and most common phase of each series
(Soil Survey Staff, 1975).
s
areas are remapped, some of the series
listed may be dropped from active use, and some of the more recently
defined series may not be on the list.
Table 2 is also an alphabetical listing of
the soil series and includes
the general soil areas where the soils are normally found; the landscape
settings
of
the soils; the parent materials that the soils are developed in;
and information on the drainage, permeability, and areal extent of the
soils. The information in this table was taken from the USDA Soil Con
servation Service blue sheet soil descriptions. More detailed infor-
. mation about the soil series can be found on these sheets and
in
published
soil surveys for the individual parishes where the soil series occurs. The
general soil areas are described in the Soil Areas section below. The
landscape setting refers to the relative position
of
the soils in the land
scape. Drainage indicates the extent to which water freely drains through
the soil profile, whereas permeability refers to the rate at which water
moves through the soil profile. The areal extent refers to the relative size
of
the total land area in which a soil series is mapped within the United
States. Thus, a soil could have a large areal extent over its total range
but have only a small extent in Louisiana.

Table 3 is a listing
of
soil series arranged by taxonomic class. The
table is divided into soil order, suborder, great group, subgroup, and
series. Family information texture, mineralogy, and temperature regime)
is listed in Table 1
Table 4 lists soil series arranged by general soil area. Some
of
the
major soil areas are further divided into subareas, and the soil series
within each subarea are listed. Some soil series are found in more than
one area, but each series is listed under the area in which it is most
commonly found.
Soil reas
The soils of Louisiana are grouped into six major soil areas based on
landscape setting and parent material. Some major soil areas are divided
into subareas as well. The major soil areas used in this guide largely
follow those
of
Lytle 1968) and Lytle and Sturgis 1962), although this
is an updated version. Descriptions of the soil areas are given below.
Coastal Plain
The Coastal Plain soil area is found in the northcentral and western
regions
of
the state and in the northeastern part
of
the Florida parishes.
Coastal Plain soils are on uplands and developed primarily in Tertiary
age sediments, although Pleistocene age terrace soils along the Red River
are included in the Coastal Plain area. These soils are not on the active
Red River floodplain and
do
not fit into the other soil areas. Coastal Plain
soils are usually in forest or pasture, although some row crops are grown.
Coastal Plain soils are divided into eight subareas based on permeability
and parent material:
1 Upland soils with rapidly permeable subsoils developed in sandy
sediments
2 Upland soils with moderately permeable subsoils developed in
sandy and loamy sediments
3 Upland
soils with slowly permeable subsoils developed in loamy
sediments
4 Upland soils with slowly permeable subsoils developed in acid
clays
5 Upland soils with slowly permeable subsoils developed in alkaline
clays marl or chalk)
6 Upland soils with slowly permeable subsoils developed in iron-
rich clayey marine sediments high in siderite
7 Upland soils with slowly permeable subsoils developed n glau-
conitic sediments
8 Pleistocene age terrace soils with slowly permeable subsoils de-
veloped in clayey alluvium

Flatwoods
The Flatwoods soil area occurs on the Intermediate and Prairie Ter
races. Flatwoods soils are typically on nearly level or depressional areas
and are usually poorly drained and have slow permeability. Vegetation
on Flatwoods soils is usually forest or pasture.
Coastal
Prairie
The Coastal Prairie soil area is in the southwestern part
of
the state.
Coastal Prairie soils have slowly permeable subsoils, and the native veg
etation was tall-grass prairie species. Rice and other row crops are not
grown on these soils.
loess
Hills
Soils developed in loess aeloian deposits with predominantly silt -sized
particles) are found in bands adjacent to the western side of the Mississippi
River floodplain and in a band adjacent to the eastern side
of
the Mis
sissippi River floodplain extending into the Florida parishes. Loessial
soils have developed under three conditions: thick loess deposits, thin
deposits of loess over sediments, and mixtures of loess and underlying
sediments. Loess deposits have been identified predominantly on Pleis
tocene age terraces but are also recognized in other upland areas. Forest,
pasture, and row crops are the predominant vegetation. Detailed infor
mation on loess and loess-derived soils can be found in a guidebook by
Miller et al. 1986).
Recent Alluvium
Four major alluvial soil areas are recognized: Mississippi River; Red
River; Ouachita River old Arkansas River channels included); and local
streams, rivers, and bayous. Within each major alluvial area, soils are
grouped according to whether they are found on the natural levees and
floodplains or in backswamp areas. A recent publication on Mississippi
River alluvial soils contains detailed information on these soils Schu
macher et al., 1988). Local stream alluvial soils are grouped into Coastal
Plain and Flatwoods stream alluvial soils, Loess Hill stream alluvial soils,
waterway spoil bank soils, and backswamp soils along local bayous.
Coastal Marsh
Coastal Marsh soils are grouped into the following categories primarily
based on landscape setting and salinity levels. These six categories are:
1 Beach and beach ridge soils
2 Saltwater marsh soils
3 Brackish
marsh soils
4 Freshwater
marsh soils
5 Drained marsh and swamp soils
6 Soils on waterway flats

The distinction between saltwater and brackish marsh soils is often
blurred because
o
the dynamic nature o the Coastal Marsh area. Salt
water inundation o brackish and even freshwater marshes
as
a result o
land subsidence coastal erosion saltwater intrusion caused by manmade
waterways wind driven tides and hurricanes is common.
