Increasing organic matter (and organic carbon) in soil requires a balance of carbon and nitrogen as well as other nutrients... Soils rarely reach their theoretical potential for organic matter storage (see Figure 1.7)... In soils with low clay content the amount of humus and resistant soil organic matter is increasingly important to nutrient exchange because its large surface area gathers (adsorbs) cations from the soil solution, holding nutrients that would otherwise leach...

Key points Introduction n The extensive rain, and warm conditions during flowering of the 2010 crop, resulted in the first wide-spread significant occurrence of head blight in wheat, durum and barley crops in southern Queensland... To avoid bunt, wheat seed should be treated with a fungicidal dressing if it has been saved from a crop grown from untreated seed...

To prevent injury, ensure that plant back periods for safflower are observed for herbicides used in the previous crop, summer or pre-sowing knockdown sprays (eg 7 to 21 days for some 2,4-D products)... At present, there are no seed applied fungicides registered for use in safflower in Australia, although some products are widely used in the United States... At present there are no fungicides registered for disease control in safflower in Australia, although some success has been achieved with seed and foliar applied products in other countries, including the United States...

Supported by GRDC Grains Research Update for Growers sponsored by.. The varieties used are poorly adapted to SA conditions, particularly with regard to boron tolerance... Barley yellow dwarf virus (BYDV) can be a threat in all environments, but is particularly important in the South East and Mid North of SA, and it is recommended that seed be treated with imidicloprid, or crops closely monitored for aphid infestation and sprayed ...

The results of the experiments have given Jeff the confidence to realise that he does have a viable, cost-effective alternative knockdown herbicide to glyphosate... Double knockdown (T 2.2b, page 128) Weather permitting, a double knockdown is implemented on resistant ryegrass paddocks prior to sowing using two non-selective herbicides (glyphosate followed by paraquat + diquat or paraquat, the choice being dependent upon the range of weeds present)... Helpful advice The Grays still enjoy the challenges and can see that they have made enough progress to feel they are being successful in mana...

The twenty drivers of the future of the industry that were identi ed by the participants at the workshop are listed below (in no particular order)... The 'internal' axis included the pro tability of farming, cost and yc availability of inputs and investment in research... The participants who developed the scenario for this quadrant were faced with conceiving what the industry would be like where climate variability and the price, availability and quality of water are conducive to the industry and government policies are supportive but the pro tability of farming is not good, input prices ...

The stubble management decisions each of these growers made in 2010-2011 were unique to the individual and were influenced by the combination of experiences, cropping systems, agronomic and logistic challenges, and commitment to full stubble retention... The value of grazing crop stubbles to farm profitability was overestimated by the ME value of the intake the value of grazing crops cannot be predicted using energy intake from stubble... Finally the burning of stubbles also contributed to weed 26Australian Glyphosate Sustainability Working Group, Australian Herbicide Resistance Institute ...
