With frost damage now estimated to be costing growers $360 million a year, the Australian National Frost Program (ANFP) is broadening its assault on the issue... Dr Juttner says methods varied across the country, so the results could not be compared... Dr Juttner says the method ANFP researchers have now developed involves staggered times of sowing, so that when a frost event hits they can tag individual heads of different wheat and barley varieties, at the same stage of development - in other words, they can compare the effect of frost on different cultivars at a synchronised developmental stage and compare like with like...

Harvest is crunch time for each year's crop, and always a good opportunity to evocatively capture on film the season's end-game.. Harvester at night in fields with moon shining through clouds... In the areas, growers suggest that early sowing, good winter rains and newer wheat varieties, such as LongReach ScoutA and Mace, have all contributed to the production achieved, despite receiving only 40mm of spring rain...

Wagga Wagga workshop to discuss frost management in 2015.. New South Wales agronomists, advisers, consultants and growers are invited to a pre-sowing technical workshop to discuss frost management in 2015... Topics will include early sowing versus late sowing; frost patterns in the Australian grain belt; assessing synoptic charts and how to use this information; row spacing, stubble and recovery; characterising frost events and their impacts on grain sterility; and variety rankings and how to use this in decision making ...

South Australian agronomists, advisers, consultants and growers are invited to a pre-sowing technical workshop to discuss frost management in 2015... The workshop in Adelaide on April 1 will be one of three forums being hosted by the Grains Research and Development Corporation (GRDC) in the southern cropping region to investigate best practice frost management ahead of this year's cropping season... Guest speakers include Mick Faulkner, from Agrilink Agricultural Consultants; Neil Fettell from Central West Farming Systems; CSIRO Climate Applications scientist Steve Crimp; Ben Biddulph from the Department of Agriculture and Food Western Australia; Tim March from the University of Adelaide; and Andrew Skinner from MEA, which designs and manufactures environmental monitoring systems...

A national network of demonstration sites, co-ordinated by key farm groups (owned and driven by farmers) in each State working in conjunction with State Agencies and CSIRO, will examine new and alternative strategies for farmers in the Australian broadacre wheat/sheep zone to mitigate the negative effects and capitalise on the opportunities of climate change on their production systems... The farm groups are uniquely situated to, not only demonstrate new practices, but also to bring awareness of the impacts of climate change and adaptations required to ensure continuing farm viability... Farmers in the dryland wheat-sheep zone will have greater awareness of the likely impacts of climate change on their production systems and are in a better position to develop practices which mitigate the likely negative impacts of climate change on their enterprise viability...

The objective of the national demonstration initiative is to establish a network of farms to demonstrate strategies for grain farming systems that address adaptation to climate change impacts... As a consequence: - Farmers and advisers have direct access to, and learning from, on-ground demonstration of new and existing, locally-relevant adaptations to climate change to maintain or enhance farm viability.- Rapid dissemination of meaningful and believable messages on adapting to climate change to their local communities.- Assessment of the emission implications of the demonstrated different adaptations using existing National Greenhouse Gas.. In collaboration with grower groups (including Facey, Liebe, North Mallee Farm Improvement Group and WANTFA), the Department of Agriculture and Food Western Australia (DAFWA) has planned a network of farms demonstrating climate risk management strategies across the central WA wheatbelt in 2011...
