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

5/32

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

6/32

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.
