Australian research is beginning to reveal the impact of farming practices on soil microbiology and how this affects the supply of yield-boosting nutrients to crops... Dr Phillips said research was exploring whether previous crops influenced microbial community functioning in subsequent cropping years; whether differences in the amount and quality of residue/stubble impacted microbial communities responsible for transforming organic and mineral N to plant-available N; and whether agronomic practices such as tillage and depth of fertiliser placement could be strategically used to manipulate N-cycling microbial communities... Caption: Soil microbiologist Lori Phillips says current research is aimed at determining the make-up of microbial communities in the soil, their role in nutrient cycling and how farming practices influence microbial activity...

The innovative website, www.soilquality.org.au , will enable growers to compare the condition of their soils with that of their regional farming counterparts... The SA node of the interactive website will be launched later this month at a soil quality workshop at Clare where growers, consultants and advisers will gather to put Mid North soils under the microscope... Program (SCaRP) which is managed by CSIRO and funded by GRDC and the Department of Agriculture, Fisheries and Forestry (DAFF), more than 100 SA farm soils (half of which were in the Mid North) have been sampled and analysed for carbon stocks, as well as a range of other chemical, physical and biological indicators of soil health...

Managing microbes to manage nitrogen.. Research into soil microbes may identify ways to keep more nitrogen in the soil and available to crops... By studying how nitrogen is processed in soil systems and which microbes are responsible, Dr Phillips can explore how agronomic practices influence those microbial communities and improve nitrogen uptake...

Specific management practices alter the abundance and activity of microbes capable of processing both organic and mineral-N... Once we better understand the soil biological and chemical factors governing N-transformations in our agricultural systems, we can determine how agronomic practices can be used to synchronise N supply, from both fertiliser and soil sources, with crop demand... A primary goal of this project was to develop and use molecular tools to detect these N-cycling communities in Australian agricultural systems...

The workshop, supported by the Grains Research and Development Corporation (GRDC), will enable local grain growers to receive expert commentary on the quality of their soils... To be held on August 28 at the Ramblers Football Club, Cummins, the workshop will introduce growers and consultants to the National Soil Quality Monitoring Program, which is funded by the GRDC through its Soil Biology Initiative II (SBI II)... The SBI II program has been able to link with sites being assessed for soil carbon as part of the Soil Carbon Research Program (SCaRP) which is managed by CSIRO and funded by GRDC and the Department of Agriculture, Fisheries and Forestry (DAFF)...

Check up on soil health with a quick click The health and quality of South Australian cropping soils is being benchmarked through an innovative online resource... The website, www.soilquality.org.au , enables growers to compare the condition of their soils with that of their regional farming counterparts... In officially launching the SA node of the website, Dr Murray Unkovich, from the University of Adelaide's School of Agriculture Food and Wine, said development of the online tool had been strongly supported by the GRDC which recognised the importance of comparative data in informing growers about the status of their soils.
