Soil health improvement
Soil
health
has been
seriously
depleted
over the
last
30-40
years
due to
abuse of
chemical
fertilizers
and
chemical
pesticides.
Useful
microorganisms
that fix
atmospheric
Nitrogen,
microbes
that
solubilize
Phosphorus,
Potash,
Zinc,
Sulfur,
microbes
that
digest
cellulose
and hemi
cellulosic
material
for its
conversion
to Humus
– the
Soil
Organic
Matter (SOM)
have
become
extinct
in these
abused
soils.
Unless
useful
soil
microbe
population
is
increased,
humus
will not
be
formed
and
organic
Nitrogen,
Phosphorus,
Potash
and
trace
elements
will not
be
available
to
plants.
All the
nutrients
applied
in any
form -
be it as
farmyard
manure /
compost
/ urea /
DAP etc
finally
will be
in
in-organic
ionic
form and
that is
referred
to as
“exchangeable
form”.
These
ionic
elements
cannot
enter
directly
in to
root
system
and they
need a
buffer
to
enter.
Humus (SOM)
acts as
a buffer
and
increases
the
Cation
Exchange
Capacity
of
roots. |
