MAKING HAY WHILE CANOLA 'SHINES': Present markets for canola hay and prices
above $500 per tonne for canola grain, are putting the oilseed back on the
agenda, even in low rainfall districts, according to Dr Steve Marcroft,
Coordinator of the Better Oilseeds project.
This project, resourced by the GRDC and the Australian Oilseeds Federation,
is working to improve canola productivity and reliability.
"Canola can generate useful income for growers and they can even make hay
from crops that struggle to fill grain," Dr Marcroft said.
"Another benefit is that wheat grown after canola is about 20 per cent more
productive than wheat grown after wheat, as canola breaks the root disease

WISING UP ON WATER: A GRDC-supported project, 'Training growers to manage
soil water', has developed a database of plant-available water capacities
(PAWC) for more than 500 cropping soils across Australia.
It is available via the APSoil database at the Agricultural Production
Systems Research Unit (APSRU) website HYPERLINK
"http://www.apsru.gov.au/apsru/"www.apsru.gov.au/apsru/ and will soon be
available through Google Earth.
PAWC is the amount of water extractable by a specific plant on a particular
According to Neal Dalgliesh, CSIRO farming systems researcher, different
crops respond differently on the same soil type and have different PAWCs.
"Crop yield predictions are commonly based on growing season rainfall, but
in dry times stored summer rainfall is an important component, with the
database providing the means for this to be taken into account," he said.
Mr Dalgliesh is keen to speak with researchers with PAWC data that can be
added to the APSoil database for all to use as a decision-support tool in
