This United States Department of Agriculture (USDA) publication (9th edition, 2003) contains taxonomic keys necessary for the classification of soils in a form easily used in the field. The book describes soils in general, how to differentiate between them, and how the identification process works. The taxonomic key includes all known soil types, including mollisols, oxisols, alfisols, and others.

The
Great
Plant
Escape
was
designed
to
introduce
students
to
plant
science,
solve
mysteries
of
plant
life,
and
increase
their
understanding
of
how
foods
grow.
In
the
lesson
plans,
students
must
identify
the
different
parts
of
plants,
what
each
part
does,
and
how
plants
grow;
find
out
what
soil
is,
why
it
is
important,
and
in
what
kinds
of
soil
plants
grow;
discover
how
a
seed
grows
into

This
resource
suggests
ways
in
which
conservation
practices
that
are
used
on
agricultural
land
across
the
country
to
conserve
and
improve
natural
resources
can
be
adapted
for
use
on
the
land
around
one's
home.
These
practices
help
the
environment
and
can
make
one's
yard
more
attractive
and
enjoyable.
Ten
conservation
practices
have
been
scaled
down
for

This
experiment
will
help
students
to
understand
the
role
of
plants
in
filtering
the
water
moving
through
a
watershed.
Students
will
discover
that
soil
and
plants
have
something
of
a
dual
role
in
this
process
and,
depending
on
whether
materials
are
dissolved
or
suspended
in
the
water,
soils
and
plant
roots
can
remove
some
or
all
of
this
material
as
the
water
moves
down
through
soil.

In
this
activity
students
work
as
a
team
to
determine
the
effect
salt
has
on
plant
germination.
They
then
use
their
lab
data
to
create
a
report
on
how
the
increasing
salt
concentrations
affected
the
germination
of
the
seeds
and
at
what
salt
concentration
no
seeds
will
germinate.
Students
will
discover
that
salt
buildup
is
an
existing
or
potential
hazard
on
almost
all
of
the
42
million
acres
of
irrigated

Fueled
by
economic
pressure
to
maximize
crop
yields
and
government
incentives
to
produce
only
one
type
of
crop,
contemporary
American
farmers
have
been
facing
a
crisis
reminiscent
of
one
that
hit
the
Great
Plains
in
the
1930s.
This
video
segment
explains
why
more
and
more
farmers
are
opting
for
sustainable,
organic
farming
practices
to
help
preserve
the
valuable
topsoil
that
they
rely
