Catalogue: GRDC 2014 Research Summaries
New stream, assay system to be developed, screening and characterisation of isolates and field trials, with decision points in Dec 2014 after initial glasshouse assays and March 2017 to engage commercial partner... The major foci of this project are to screen and identify elite disease-suppressive microbes for cereals and nodulation-enhancing beneficial microbes for legumes... The Program will consult and work with potential commercial partners, eg Novozymes Biologicals, Becker Underwood, New-Edge Microbials, ALOSCA Technologies, thereby providing mechanisms to ensure communication of research outcomes and successful commercialisation of inoculant products...

Application of nitrogen to most crops will affect grain yield, grain protein or both, depending on the available nitrogen supply relative to crop demand... Soil analysis conducted recently have indicated that EC, sodicity and chloride content have increase in the root zone of some soils due to capillary rise arising from the extended dry period... Environment mean yield (t/ha) d) Reduced tillering Several years ago I proposed that the incidence of haying-off could be reduced by increasing the storage of stem sugars by several means...

In 1993, Ralph Valler, from Chinchilla, Queensland, was one of the first grain growers to use the N-Jector, a device that enabled him to apply anhydrous ammonia with seeds.".. If you put anhydrous ammonia near the seed it will kill it... In the search for other ways to improve his soil, Mr Valler started trialling microbes...

Recent research has found that plants react defensively to both classes of microbes, raising new questions about conventional approaches to managing soil microbes for crop health... Researchers such as Canadian-born Dr Jonathan Plett have established that even beneficial rhizobial microbes that form root nodules and provide plant with nitrogen are actually acting a lot like plant diseases... "Rhizobia are able to fool the plant to some degree, taking over control of some biological functions so the plant can't fight off the invading microbes," Dr Plett says...

Lastly the strain is selected for its ability to survive in the soil between seasons... Let's consider if there is a need for inoculation of the crop with free-living N2-fixing organisms... The production of cluster roots and release of organic acids is extremely energy expensive; the plants strategy is to acquire P at any cost (Lynch and Ho 2005)...

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...
