Crop resilience patiently built on soil health.. Stuart says on-farm trials over the past eight years show that inputs costs equate to one tonne of a two tonne per hectare crop but 2t of a 3t/ha crop... "The results show more nitrogen, phosphorus and potassium are available when organic matter is introduced, and that there is more stored water in the top 10cm and no limit to the number of microbes, provided there is sufficient organic carbon," Stuart says...

New smart technology apps to help grain growers better manage their operations have been developed and released through the GRDC and Australian Year of the Farmer Grain Inventors Award... The apps are an extension of Mr Fels's personal data-modelling technique and iPad-based farm-management system that he created to keep up with the organisation and coordination of his rapidly growing farm business... After witnessing the cost savings, efficiency gains and improved profits of this system, he decided to take the next step and develop commercial iPaddock apps for mobile devices...

You typically find that the depth to the salt bulge decreases to the west... We have concluded that chickpeas were not as effective as wheat in adjusting yield components under prolonged water stress... The grain yield in the SF early burn and cultivated treatment (2.5 t/ha) was comparable to the other SF treatments in the dry 2002 season despite having the lowest incidence of crown rot infection...

Farming systems which minimise the movement of soil and water will also minimise the loss of nutrients and pesticides... Overall, the only large difference was the lower Zn when superphosphate was applied... In summary, Mike has found a strategy to help him interpret his yield maps - and is now taking the same approach to other paddocks to maximise fertiliser savings...

GRDC values the contributions made by its research partners during the 2004 series of Grains Research Updates.. Overall, there were 50 comparisons, 45 showing a positive yield increase with fluid and 5 with no yield difference... Overall, there were 11 comparisons, with 4 yield decreases due to fluids and 7 with no yield differences...
