" Managing soil microorganisms to unlock the P bank in soil: Taking back what.. Much of the remaining fertiliser P becomes fixed in soil and the P 'bank' in Australian arable soils is estimated to be worth $10 billion, or 100 kg P/ha of arable land (Cornish 2009)... The Australian grains industry needs new strategies to increase plant access to fixed P in soil that don "t compromise productivity, income or soil fertility  Let "s take back what "s ours!This project will identify practical agronomic strategies allowing grain growers to pro-actively manage microbial release of fixed P and P...
GRDC Taxonomy:
Australian farmers have incurred heavy losses due to frequent drought in the recent past as current chickpea varieties are not adapted to drought, cold and saline conditions besides the killer diseases like Fusarium wilt (FW), Botrytis grey mould (BGM) and Ascochyta blight (AB)... The losses caused by these stresses can be avoided by genetic options such as incorporating resistance genes and managing the stresses through chemicals and agronomic approaches... The improved varieties, once adopted by Australian farmers, will imply higher and stable grain yield with better grain quality and wi...
GRDC Taxonomy:
The Australian grains industry needs accurate information on the costs of these stresses at a national scale to guide management decisions and remediation to minimise productivity losses... Also a number of methodologies have been used in the past to estimate costs of these stresses using various assumptions with varying levels of success... A desktop study of current information available nationally on the extent, impact and methodologies to determine costs of soil-induced stresses to the Australian grains industry will be collated and reviewed by 30 December 2013...
GRDC Taxonomy:
The University of Sydney manages several collaborative programs with India funded through the Generation Challenge Program (GCP) and the Australian Centre for International Agricultural Research (ACIAR)... The programs develop germplasm with stress and disease resistance specifically for India by crossing Australian and local germplasm with subsequent selection for key traits using a combination of molecular markers and phenotypic screening... The materials, derived using a combination of double haploids and traditional selection, have been developed at the Plant Breeding Institute and the...
GRDC Taxonomy:
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 too...
GRDC Taxonomy:
Over the last decade there has been a significant focus on reducing the environmental impact of products and services across the economy... All primary industries, including the grains industry, are under increased public scrutiny about the way food is grown... Life Cycle Assessment (LCA) is the most commonly used tool to determine the environmental impact of a product, by taking into account all of the impacts across the supply chain and across different impact categories...
GRDC Taxonomy:
Current frost phenotyping methods used within the Australian National Frost Program (ANFP) are based on frost induced sterility at flowering... This estimation of varietal response to frost assumes the reduction in grain number is the main yield component affected... There has been limited work evaluating the effect of frost induced sterility on yield components (grains per m2, spikes per m2 and grain weight) and final grain yield or for variation in this under frost...

" Online Final Reports Research- Innovative Knowledge Management Approaches to Support Greater Research Uptake Researcher's Name: Dr Helen Thompson Organisation: Federation University of Australia (formerly University of Ballarat) Email: h. thompson@ballarat... The GRDC is committed to ensuring growers and their advisers have greater access to and can make more effective use of the outputs of past research... Over recent years, the GRDC has focussed on making information accessible for extension programs and ultimately to improve the speed and probability of adoption...
GRDC Taxonomy:
3) It is widely accepted that fungicide applications are generally most effective when applied with small-droplet technology, but such applications are also associated with the highest risk of spray drift... The project is about optimizing pesticide spray applications by: identifying spray technologies and spray settings with low risk of spray drift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides and minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacy against target pests... A key...
