" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

The database underlying the BFDC Interrogator contains the results of more than 5000 soil test calibration experiments conducted in Australia since the 1950s... Soil test-crop response (N, P, K and S fertiliser) trials have been undertaken by many different organisations in Australia since the late 1950's... There have been a number of scientific publications (Crop & Pasture Science Special Issue, Volume 64) derived from the trial data contained within the BFDC dataset...

Crown rot is likely to rear its head once again this year growers can minimise its impact on yield potential by undertaking a paddock disease assessment prior to planting, selecting appropriate varieties and knowing seed purity... Crown rot is caused by the fungus Fusarium pseudograminearum and is one of the most serious disease threats to winter cereal crops in Australia... The DNA-based soil testing service PreDicta B is a reliable medium for identifying the level of risk for crown rot and other soil-borne pathogens prior to sowing but it is important to remember that using the correct sampling technique is critical to its accuracy...

Large group of people standing in line gazing into a crop field.. Growers inspecting Crown Rot Analytical trials at Bellata... A PreDicta B test can be arranged by contacting commercial testing service, Crown Analytical Services, which provides northern growers and advisors with bags, soil corers, protocols and procedures for sampling as well as an interpretation of results once tests are completed by the South Australian Research and Development Institute (SARDI) in Adelaide...

Wheat, sorghum, pulses (chickpea, peanut and mungbean), and sunflowers are very important components of the GRDC northern region farming systems, with a combined farmgate value of well over $1 billion pa... The first two crops are the mainstays of these systems, with pulses and sunflowers not only providing niche opportunities but also being break crops with significant soil nutrition and biology impacts... Diseases of the crops have considerable impacts on crop profitability and farm enterprise sustainability...

While commercial varieties of bread wheat and durum wheat with adequate levels of crown rot resistance are not available, other wheats carrying a level of resistance or tolerance to this disease have been identified... The markers will be used as flags to detect the presence of resistance genes in populations of wheat plants derived from crosses between resistant lines and elite varieties... Readily detected genetic markers are identified that indicate the presence of genes that resist growth of, or provide tolerance to crown rot disease...

Hot dry conditions exacerbate crown rot threat.. "This year many crops have simply run short of stored moisture and plants have had to expend additional energy to uptake limited moisture for grain fill from a greater depth in the soil... The Grains Research and Development Corporation (GRDC) advises growers to assess crown rot risk by checking for browning of the stem base or by taking soil and stubble samples for analysis...

We focused on the N 2 O emissions associated with the growth of annual legume species, the subsequent breakdown of their residues, and the uptake of their residual nitrogen by a following wheat crop... Results from the project ranged from 0.08% to 0.59% using fluxes calculated by a non-linear interpretation of gas concentration data, and slightly less using a simpler linear regression approach... The losses measured at this time were comparable with those measured under similar conditions in winter, but where there was twice the rate of fertiliser N applied, the potential for N 2 O losses appears to be much higher in the summer period...
