Well- structured soil has plenty of crumbly aggregates; organic matter is essential for these.. A well aggregated soil allows smooth flow of water, air and nutrients, promotes root growth, aerobic microbial activity, and earthworms and other fauna activity... Management practices that improve or maintain soil structure, surface cover and no-till and appropriate nutrition leads to better water use and improved water use efficiency, which is critical for sustainable grain production in the rainfed, semi-arid subtropical northern grains region...

Maintaining market access - keeping it clean (Adelaide).. GIMAF continues to play an important role in coordinating industry efforts to maintain and improve market access for Australian grains in an impartial manner... Since establishment in 2011 GIMAF has actively pursued issues through the Department of Agriculture and the Department of Foreign Affairs and Trade (DFAT), providing input on country to country free trade agreements and directly engaging with customer countries...

In cracking clay soils of the northern grains region, saturated soil conditions between fertiliser application and crop growth can lead to significant N losses from the soil through denitrification... In 2010, the nitrous oxide emissions measured in the first month (143 mm rain) after sowing wheat averaged 53% of the total measured for the full 12 months after sowing... Our previous research also highlighted the potential for losses of non-fertiliser N from denitrification...

Figure 1 Chloride fertiliser application rate affects the whole plant tissue concentration of chloride.. Since then, we carried out several further chloride addition field experiments across the Liverpool Plains in 2009 and we report the results of those ... The durum advanced yield trials consisting of current varieties and elite breeding lines at Tamworth Agricultural Institute and on-farm at Currabubula both exhibited severe chloride deficient leaf-spotting symptoms and we report the results of tissue testing and leaf-spot scoring / measurement on all 32 lines grown at those trials (lea...

CSIRO has a long track record of making major on-going investment into the genetic improvement of wheat varieties and their agronomy to ensure they fit the target requirements for both the main wheat belt and the High Rainfall Zones of Australia... Underpinning the development of the traits provided to Australian breeders are a series of basic technologies that we are applying to our work... We outline the state of current research efforts supported by public funds (CSIRO, GRDC) with particular emphasis being given to developments that we believe will assist plant breeders in Australian br...
Catalogue: 
Grain prices at 2007/08 levels provide an opportunity to increase crop intensity and production with a reduced financial risk and higher financial reward cost control and monitoring remains the key to business success... Higher cost of inputs for fertilizer, sprays and fuel will increase the financial risk... Decision Support Tools help farm business mangers to determine their financial risk and exposure...
Catalogue: 
The value of the extra crop yield attributed to fungicide use is estimated at $1200m for wheat and $2000 for all crops... We suggest that further research is needed to.. Overall, we believe the best way to preserve the value of chemical methods of crop protection is to..

" Date: 11.07.2008 THE IMPACT OF CROWN ROT ON WINTER CEREAL YIELDS.. Trials were assessed for plant establishment and harvested by small plot headers to attain grain yield and quality... Screenings results did show a much larger impact from the addition of crown rot...
Catalogue: 
The barley and wheat cultivars bred for the Northern Region are routinely tested for their tolerance to herbicides in three stages... The research is undertaken in weed-free sites in southern Queensland, where yields are compared between those sprayed at a recommended and double rates with the untreated controls for each cultivar... The paper presents the results on the advanced screening of the herbicide tolerance of the new barley and wheat cultivars that have been released in the last five years...
