microbial community

Catalogue: GRDC Media
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...

Soil microrganisms also impact on the physical properties of soils including their capacity to hold water... An on-going output will be the coordination of review workshops and reporting processes to ensure that adequate resourcing, integration and consistency measures are being applied across all projects and new opportunities are identified... The major foci of this project are to screen and identify elite diseasesuppressive microbes for cereals and nodulation enhancing beneficial microbes for legumes...

We propose to use a polyphasic approach involving (i) comparative analysis of high- and low-suppressive soils, (ii) pre-treatment or prior exposure of soils to factors that have been attributed to the development of disease suppression and (iii) amplification of target regions prior to high-throughput sequencing... The use of direct soil DNA/RNA extraction technologies will help overcome the bottlenecks associated with the culture based methods... We propose to establish close working links with other projects in SBI-Theme 3 for field sites used, consistency in methodologies and complementary research approaches...

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 potential for changes in soil microbial function for improved productivity through intensive cropping systems were evaluated in this project... A resilience test in which soils are exposed to repeated wet-dry cycles provides a suitable assay to determine changes in the stability of microbial functions... Results from the project demonstrated the likelihood of changes in microbial functions relevant for increased nutrient efficiency and productivity by altering C inputs through the use of intensive cropping systems...
