 REGIONAL FOCUS FOR FUTURE ENERGY: Future grain based energy production
scenarios and self sufficiency opportunities for graingrowers are moving
from a national to a regional production focus as part of a 2007/08 GRDC
supported CSIRO sustainable energy project. <?xml:namespace prefix = o ns =
"urn:schemas-microsoft-com:office:office" />


CSIRO Sustainable Ecosystems researcher, Dr Deborah O'Connell said future
energy planning on a regional scale had never been attempted before.


"Price fluctuations and geographic issues vary between regions, so the new
project examines regional energy efficient production and biofuel
opportunities for graingrowers," she said.


"Phase one involves selecting two or three grower case studies and
conducting regional workshops, in close liaison with GRDC regional panels
and regular advisory committees.


"Subject to phase one's success, phase two involves conducting the case
studies in the chosen regions and is planned to start mid-2008," Dr
O'Connell said.

NOVEL WAY FOR K: University of Western Australia researchers have uncovered
a novel approach to fertiliser management, optimising potassium (K)
management by measuring genotypic tolerance to soils with low K


With GRDC support, the UWA Crop Nutrition group, led by Professor Zed
Rengel, investigated the magnitude of K efficiency variation of canola,
barley and wheat genotypes.


He said that in the GRDC supported trials, research officer Paul Damon
discovered canola genotypes Wesbarker and Rainbow were K-efficient and could
improve canola yields on soils with low K availability.

"Wheat varieties Carnamah and Wyalkatchem also maintained high yields with
low soil K availability and Nyabing and Nabawa could tolerate low K
concentrations in shoot tissue," Professor Rengel said.


"The new approach will ultimately help graingrowers develop better nutrient
management practices and reduce the financial and environmental costs of
wasted fertiliser."
