The soils of
Madison County were mapped by USDA from 1966 -1973. The
soil delineations were drawn over 1974 aerial
photography and published as the
1978 Soil Survey of Madison County. Since then all soil
surveys across the country have been digitized and can
be accessed on the web through the
Web Soil Survey. Below is a link that takes you
directly to the Madison County Map of the Web Soil
Survey. The link is followed by instructions on how you
can use the site to make a soil map of your property.
Madison County Soil Map via Web Soil Survey
takes you directly to the Madison County
map of the
Web-Soil-Survey. You can zoom to an aerial photograph of your
property "area of interest, i.e., AOI" through
which a soil map can be generated and layered over the aerial
photography. Once an AOI is generated various
soil reports can be generated for your property. You can
click on the Legend Tab to view a USGS topographic map.

2. Zoom to
your property "AOI"
a. Use your mouse to move the cursor to the general area
of your property.
b. When the cursor is outside the north and west
boundaries of your property left click your mouse and drag
your mouse to move the cursor to outside the south and east
your property, then release the left click. To zoom in
closer repeat steps until you are zoomed in to your
your property boundary "AOI"
a. left click the AOI button "the one with the irregular
shape" this will activate the tool.
b. move the cursor to a point along your property line
and left click your mouse to start drawing the area.
c. keep moving the cursor along your property line left clicking at each directional change of your property
d. when you get to the point when the last straight line
will take you back to where you made the first click,
double click the last point to finish drawing your
property lines. The area of your property "AOI" will become
soil map of Your property "AOI"
a. After you have drawn the outline of your property
"AOL" and your property is highlighted, click the Soil
Map tab. A soil map of your property will overlay the
aerial photography. A table will be generated showing
the acres of each soil on your farm and the total acres of you
soil reports of your property "AOI"
a. Click on the Soil Data Explorer tab. Several general
report options will appear each with several specific
report options. Follow instructions to generate soil
reports for your farm.
The soils of
Madison County were first mapped in the early 1900s and
were issued as
Survey of Madison County. The
mapping was very general and consisted of only four map
the foundation for man's civilization. It provides us
with vast quantities of natural resources that we mine,
process, and transform into useful materials. The top
few inches is known as top soil. If it is healthy it is
teaming with life and is the growing medium for many of
earth's plants. Most all the food we eat including meat
are derived from these plants. Our lumber comes from
plants as well as our cotton clothes. This first
few inches of the earth's crust is essential to life. It
is these first few inches, the top soil, that we as a
soil conservation district are concerned with
conserving. It can take nature over one thousand years
to develop one inch of top soil. If we don't use our
soil wisely we can wash away one inch of top soil in
less than one year. Thousands of acres of top soil are
developed and paved over each year to provide us with
roads, houses, factories, schools, hospitals, shopping
malls, commerce centers, and on and on. There are over
7 billion people populating the earth. By 2025
it is estimated that there will be another billion
people for the earth to provide food, shelter,
transportation, manufacturing, and commerce. As the
earth's population increases it becomes ever more vital
that we use our top soil wisely.

Madison County consists of some 358,000
acres; 559 sq. miles. The soils of the County formed
mostly in deposits of wind blown materials over costal
plains material and are mainly silt loams or silty clay
loams. The land is gently rolling to hilly. The
elevation difference from the highest point in the
county, 650 above sea level, to the lowest point in the
county 310 feet above sea level, is only 340 feet. Most soils
on uplands erode easily, and control of runoff and
erosion is imperative. The soils are low in
organic-matter, phosphorus, and potassium and are
strongly acid to very strongly acid. However,
where drainage is adequate and slopes are gentle, the
soils respond well to additions of lime and fertilizer
and produce good yields. In 2009 the average per
acre yields were 148 bushels of corn, 899 lbs. of
cotton, 42.5 bushels of soybeans, and 56.5 bushels of wheat.
The soils for
any property in the U. S. can be accessed on the
internet through the USDA - NRCS
Web Soil Survey.
When you visit the site, click the large green button
and a map of the U. S. will appear. You can zoom to
smaller and smaller areas until you are where your
property is located, or you can use the search aids to

get to the general location of your property follow the
above steps to develop a soil map.
