Catalogue: GRDC Updates
GRDC is supporting research to better understand inversion conditions and to provide resources to anticipate and recognize inversion conditions... Temperature inversions suppress vertical motion of the atmosphere and thereby cause concentration rather than dispersion of pesticide droplets, vapour or particulate matter that remain airborne after application... The risk of spraying when inversions exist There is real potential for small droplets, vapour and particulate matter to drift for long distances at high enough concentrations to contaminate and damage sensitive crops and the environment...

Grain yields can be increased through greater transpiration efficiency (TE), a measure of the efficiency with which water is exchanged for carbon dioxide during photosynthesis... Oil composition can be compromised and lead to a change in fatty acid profiles if the seed is harvested when too moist, the seed has been excessively thrashed, admixture / moisture and disease levels are too high or the temperatures in your silo reach 35 C plus for more than 3 or 4 days in a row... For the reasons above, we need a cropping/pasture rotation..

South coast soils turned upside down.. "Where we used the machine, the canola roots had penetrated to a depth of 18cm in the first four weeks after sowing, compared with 8cm for canola roots in the untreated area," he says... "Behind the discs, we have tynes spaced at 280 millimetres that plough to a depth of 30cm, bringing clay to the surface, busting it up and spreading it through the soil profile," Ashley says...

" GRDC Grains Research Updates 6-7 February 2013, Southern Region, Ballarat VIC. Helen Suter 03 October 2013 Helen Suter, University of Melbourne discusses her research into the impact of urease inhibitors on ammonia loss... Ammonia loss from surface applied granular urea can be high, with up to 30% loss recorded from pastures in southern Australia... Ammonia loss from surface applied granular urea is highly dependent on micro-climatic conditions...
