Experimentation will focus on molecular techniques to understand the activity of soil microbial communities in releasing nutrients, coupled with detailed measures of soil nutrient cycling... Molecular techniques to understand the soil microbial communities role in nutrient release will be applied to field experiments to determine whether these soil biological processes can be manipulated through agronomic management to improve the prediction of nutrient cycling and crop productivity... Information from both outputs will be used to evaluate whether the presence and activity of these soil biological communities can be modified by different agricultural practices...

For millenia our farmers have been harnessing the activities of soil organisms to provide society with food and fibre... Microrgansisms cannot be seen but without them our soils would be unable to support plant growth... Through the national program, an innovative website, www.soilquality.org.au, has been launched to enable growers to compare the condition of their soils with that of their regional farming..

Growers praised for efforts to preserve healthy soils.. On the eve of World Soil Day (December 5), Grains Research and Development Corporation (GRDC) Managing Director John Harvey says it is timely to acknowledge the grains industry's efforts in ensuring the long-term fertility of soils, necessary for essential food production... Scientists involved in the Soil Biology Initiative agree that the program is making considerable progress in understanding the composition of the living fraction of soils which support crop production, and how growers can best manage soils to maximise nutrient capture and defend against crop disease...

" Assessing management options for enhanced soil phosphorus availability using rotations.. The proposed work aims to identify if there are rotation options that can provide an agronomic management solution for the release of fixed P in a range of soils across the grain growing regions of Australia... If the outcomes of this proposed project demonstrate the potential for growers to unlock 1% of the P bank annually by rotation management this would be equivalent to release of $50-100 million worth of fertiliser P (about 10% of the current annual investment of $1.4 billion in P application to grains in Australia)...

On the eve of World Soil Day (December 5), Grains Research and Development Corporation (GRDC) Managing Director John Harvey says it is timely to acknowledge the grains industry's efforts in ensuring the long-term fertility of soils, necessary for essential food production... "We don't fully understand the biological composition of our soils and how they function and contribute to grain production, so there is enormous scope for developing some new thinking about how we should treat and manage our soils and the practices we can put in place to drive productivity and profitability.".. Scientists involved in the Soil Biology Initiative agree that the program is making considerable progress in understanding the composition of the living fraction of soils which support crop production, and how growers can best manage soils to maximise nutrient capture and defend against crop disease...

Soils that are able to withstand or reduce the extent of crop damage from a soil-borne disease incursion are referred to as disease suppressive soils... While the soils have been identified in all grain production regions little is known about the soil bioogy that confers disease suppressive qualities on a soil... The development of new tools to monitor disease suppressive soils will ultimately benefit farmers by allowing management practices to be linked to transferring or improving disease suppressiveness in soils...
