burning power plants and
heating
plants
produce
a great amount of wood
ash as
a
by

product of
the
combustion
process
. In
2009 we launched an experiment in which
we examined
the
composition
of ash, the nutri
ent
suppl
ying
capacity
of soil mixed with ash, and the
availability
of
its
constituents
. In the spring of 2010
, we conducted
small
plot
experiments using wood ash applications
equivalent to 0; 1; 2.5; 5 and 10 t
of
wood
ash/ha
,
on
s
lightly acidic clay loam soil
using
white mustard
and rye grass as the test plants
.
T
he pH value of the soil
rose
in a statistically verifiable way
as a result
of the ash treatments
. After the
application
of ash
,
the P

rose
significantly
;
t
he treatments
also
i
ncreased the magnesium and sulphur
content of the
arable
soil
as
well as
the
level of Zinc among the microelements.
However, n
one
of the wood ash
applications
caused verifiable changes in the number of shoots, in the green mass
,
or in the height of test plants.
The
increased
nutrient supply
of
the soil
through
the treatments was not reflected
i
n
the nutrient
content of the plants during the first year.
