Use
of
Microbes
for
Improving
Soil
Fertility -
Tthe
use
of
mycorrhizae
to
enhance
the
uptake
of
nutrients
and
water
for
establishment
of
seedlilngs
on
degraded
lands.
This
will,
however,
not
lead
to
improvement
of
soil
fertility
by
mycorrhizae
as
such,
although
the
success
of
plant
growth
will
eventually
lead
to
reclamation
of
degraded
lands.
However,
nitrogen
fixing
bacteria
like
Rhizobium
or
actionomycete
genus
Frankia
can
be
used
to
induce
nodule
formation
in
a
variety
of
plant
species,
so
that
these
can
be
used
for
improving
soil
fertility
of
degraded
lands.
This
nodule
formation
can
be
induced,
both
in
leguminous
and
non-leguminous
plant
species
comprising
annuals
(cereal
and
legume
crops)
and
perennials
(trees).
Efforts
are
underway
to
manipulate
the
genes
of
both
host
and
rhizobia
to
obtain
maximum
efficiency
of
nodule
formation.
Strains
are
also
being
tailored
for
unusual
soil
environments
representing
degraded
lands.
