Grain growers looking to bolster their profits in 2014 should start planning now by adding the Grains Research and Development Corporation (GRDC) Updates to their diary... Coonabarabran will host an advisor update on February 26 and 27 at the Town Hall; a grower update will be held at Nyngan Bowling Club on February 28; Goondiwindi will host an advisor update on March 4 and 5 at the Goondiwindi Community Centre; and a grower update will be held at the Mungindi Community Hall on March 6... Update coordinator John Cameron, ICAN Rural, said the updates would address the latest information needed to drive on-farm adoption on key topics such as bridging the yield gap between environmentally achievable yields versus actual yields, the effective use of pre-emergent cereal herbicides, herbicide resistance and weed management, crop nutrition, disease, varietal selection and soil water management...

14 BWD00024: Maintaining profitable farming systems with retained stubble in Victoria and Tasmania .................................... The over-arching aim of the project is to improve yield and water-use-efficiency of irrigated wheat production across the Northern Region by developing improved agronomic practices to reduce the incidence of lodging and increase the yield potential of irrigated wheat... Overall, the project will deliver a comprehensive research, communication and extension program that will ensure more effective management of water repellent agricultural soils in WA whilst building capacity for future soils research and development in Western Australia...

Changes to farming practices and resultant improvements to water storage efficiency, coupled with the high variability in climate, have increased demand for improved understanding of soil water management in agriculture... Investigation of technologies to expedite measurement of soil water has resulted in the development of the tools, SoilMapp and Soil Water Express and improved understanding of the potential for electromagnetic induction (EMI) and spectrometry to contribute to soil water management... If the accuracy of decision support tools is to be increased, there is a continuing need for the characterisation of soils at the paddock or broader spatial scales to fill existing data 'black holes'...

Over recent years soil water has become an increasingly important component of crop management in Australia?s broadacre cropping systems... This project builds on previous research (GRDC CSA00011) providing more advanced soil water management training to agricultural consultants and farmers, expanding the regional characterisation of soils for PAWC and assessing technologies for the rapid characterisation and monitoring of soil water resources on-farm... The development of the Soil Water Express, provides users with the potential to undertake a rapid, but less accurate, prediction of PAWC based on locally derived soil data and functions developed from information contained in the APSoil database...

Whilst managing the water balance of crops is one of the most critical issues in Australian dryland agriculture, there has been limited information available to farm managers that allows the productive capacity of soils to be considered when making crop management decisions... Evaluation of project activities showed that whilst growers were interested in soil water management and were prepared to use Yield Prophet as a tool for in-season crop management, they generally relied on their consultants to undertake the pre-season monitoring and input of data... Whilst the project has had a major influence in promoting the value of soil water in management, there is an on-going need for higher level training as well as the development of increased capacity in soil characterisation and monitoring through the exploration and adoption of new technologies...

Previous soil research and extension has resulted in more than 1,000 farmers and consultants receiving basic training in soil-water management and more than 900 Australian soils being characterised for water-holding capacity (PAWC)... Whilst the information is now being used as the basis for crop management decisions around Australia, there still remains a need to provide more training and field characterisation to meet on-going demand... The demand is the result of increasing adoption of technologies that allow growers to monitor soil water in real time and the use of decision support tools that allow growers and advisors to investigate crop management options based on seasonal climate and resource status (water and nutrients)...

The development of the Soil Water Express, provides users with the potential to undertake a rapid, but less accurate, prediction of PAWC based on locally derived soil data and functions developed from information contained in the APSoil database... Whilst in-situ electronic monitoring devices including NIR and capacitance probes provide an adequate picture of soil water in rigid soils, they were found to be inappropriate for shrink/swell soils where cracking and soil movement interfere with accurate recording...
