Good P nutrition is critical in early crop development to
maximise yield potential.
Apply CataPultTM at planting at 1.75 kg/ha mixed with seed
or starter fertiliser.
CataPultTM allows access to the bank of bound P in many
CataPultTM increases yields.
CataPultTM decreases P application rates (eg 25-50%)
making light applications of P work better.
VAM in CatapultTM also harvests water and helps crops
grow through dry spells.
The combination of phosphorous

THE Hart Field-Site Group launched its
2013 trial results book at the Getting the Crop
In seminar in Clare last Wednesday and in a
first for the group, announced it is now avail-
able to download free online.
The new online format complements the
trials book still available in hardcopy and Hart
Field- Site Group chairman, Justin Wundke,
says it gives readers the opportunity to choose
a format that best suits their needs.
“The online format has been introduced
to provide easy-access to our agronomy trial
results to everyone in the agricultural commu-
nity, not just our members,” Mr Wundke said.
“It means the information can be accessed
free, at any time, anywhere and gives readers
the opportunity to either download the whole
trials book, or just read the trials that are of
particular relevance to them.
“The trials book is still available in hard
copy for those readers that prefer to have it
on hand, but the online format just provides
another option for access to information.”

from 2009-2013 are now available online at

CataPult helps speed root growth
CATAPULT is a new product to
the market and is creating a lot of
interest in South Australian wheat
The product uses a convenient
granular formulation to deliver a
combination of VAM mycorrhizae
and selected species of phospho-
rous solubilising microbes.
The distinctive blue granules
are applied at planting with either
the seed or starter fertiliser.
This enables farmers to use
biological approaches without
the usual requirements for special
The release and catch technol-
ogy refers to the action of the
Bacillus microbes in solubilising
bound phosphorous (release) fol-
lowed by the action of VAM in
capturing P very efficiently for the
VAM forms a very extensive
network of hyphae in the soil and
this acts to ‘find’ P to deliver to the
Many soils have a large bank of
bound P that is usually unavailable
and CataPult allows access to some
of this P.
As well as problems with bind-
ing and unavailability P does not
move much in the soil so roots have
to grow into soil particles to find it.
A ‘zone of depletion’ soon
develops around the root hair and
the VAM hyphae spread out past
this to absorb other P that may be
available but just isn’t found by
the root hairs.
The Bacillus species also pro-
duce growth factors (auxins) that
drive fast early root growth (see
