The latest in evidence-based scientific data on cropping soils, carbon sequestration and farming systems will be presented at the upcoming Grains Research and Development Corporation (GRDC) Update being held in Goondiwindi... World renowned expert in soil systems, Professor Iain Young from the University of New England will explore soil, plant and microbe interactions in cropping soils and provide an international perspective that advisers and growers can't afford to miss... "The Update is a chance for growers and advisers to tap into the latest research, liaise with our expert local and international guest speakers and become better informed on ways to boost productivity on farm in a more sustainable manner."..

The publication has been prepared in good faith on the basis of information available at the date of publication... Products may be identified by proprietary or trade names to help readers identify particular types of products but this is not, and is not intended to be, an endorsement or recommendation of any product or manufacturer referred to... There is huge scope in the available moisture stored in the soil provided the right approaches are taken to issues such as crop nutrition, seeding systems and crop management...

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..

PEM bacteria are important as they are common, suppress multiple diseases, interact with other organisms to increase suppression and can be correlated with reduced disease in the field... Crop selection could be used to increase suppressive microbes and enhance disease suppression on-farm... In summary, the project increased our understanding of disease suppression and the organisms involved, identified potential biocontrol inoculants that can reduce disease in the field as seed coatings to provide in-season Rhizoctonia disease control, and identified a potential strategy using crop selection to increase naturally occurring disease suppression in the field to provide long-term control of soilborne fungal diseases...

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...

This project aims to develop DNA tests to quantify Free Living Nematode (FLN) groups in soil, which will be useful indicators of soil quality... Nematodes are useful biological indicators of soil health because they: occur in all soils; are readily extracted and identified; have a wide range of food sources; are ecologically and taxonomically diverse; and respond to changes in food sources, as well as soil physical and chemical properties Indices derived from nematode community analyses can be used to provide information about a soil ecosystem with respect to nutrient status, presence of pollutants, disturbance and disease suppression... The project will provide information on free-living nematode communities in key Australian cropping soils, identify groups which will be useful to assess soil biological health and link analysis to soil quality monitoring...
