soil biology symposium

Catalogue: GRDC Research Summaries
Grain growers, advisers and researchers are invited to attend a free national symposium in May to learn about the latest soil biology research... Ground Cover Radio 116: Start digging for inoculant success check up.. Growers are being encouraged to grab their shovels and look below the soil surface to check if legume inoculants are working...

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..

Data presented showed that farm practices that have a positive impact on soil biology include no-till, effective crop sequencing (rotations), lime applications and building up soil carbon... Soil microbiologist Dr Lori Phillips of the Victorian Department of Environment and Primary Industries (DEPI) says there are direct links between the microbes that release nitrogen from crop residues and soil sources, and the microbes that convert fertiliser nitrogen to crop-available nitrogen... In related research, the University of Western Australia's Professor Dan Murphy said his work had shown that organic molecules released from plant roots had more influence on the microbes that can retain (immobilise) nitrogen than soil organic carbon levels...

" Supporting a global program to establish soil metagenomic databases for iconic grain production trials.. Soil Biota mediate several processes that grain production systems rely upon for sustainable profitability... The nascent BASE (Biome of Australian Soil Environments) project, builds on recent efforts in metagenomics, microbiology, invertebrate and plant ecology to create a coherent database of the genetic diversity present in Australian soils; while the construction of this database will reveal many insights into the functional relationships underpinning soil health, the primary aim is to generate a publically available reference dataset that will act as a baseline for studies of ecosystem change for the decades to come...

The proposed work capitalises on new knowledge demonstrating the highly significant role played by beneficial symbiotic arbuscular mycorrhizal (AM) fungi in supplying P to cereals... The new findings show that there is a switch from direct root uptake to AM fungal uptake in AM cereals and that the fungal symbionts have the potential to make a major contribution to the biological capacity of soils to deliver P to the crop plants and contribute to P cycling...
