The GRDC Soil Biology Initiative (SBI-II, 2009-2014) has partnered with research organisations throughout Australia to work towards the 10-year vision of increased profitability and sustainability of grain cropping as a result of harnessing the biological potential of soil... Timing of N fertiliser additions: Minimising or eliminating fertiliser applications at sowing will enhance microbial processing of soil organic N. Mineralisation measures: Molecular tools that measure the microbial genes associated with organic N release may be used to assess the mineralisation potential in a wide range of soils... Objectives: The project aimed to determine if populations of AM fungi (AMF) in soil are influenced by growth of different break crops, so influencing AM colonisation in the following wheat crop and delivery of soil phosphate (P) to the plants via the AMF. We use a novel method of estimating this delivery separately from direct P uptake by the roots, using radioactive P ( 33P)...

Pursuing the mystery of disease-suppressive soils.. The GRDC is funding a suite of projects to identify and harness the biological traits associated with suppressive soils.. Mechanisms of disease suppression are identified using RNA sequencing technology to examine the genes that are switched on in suppressive and non-suppressive soils prior to sowing and six to eight weeks after sowing, when young plants can be infected by R. solani ...

The GRDC is funding a suite of projects to identify and harness the biological traits associated with suppressive soils.. The project is looking to identify the key organisms involved in the suppression of root lesion nematodes and which soils might best support these organisms...

Soil secrets to suppress disease.. Associate Professor Pauline Mele from La Trobe University looks for the soil microorganisms that suppress disease in grain crops... A team of 90 researchers working on 15 projects aim to increase yields and reduce input costs in soils across the high-rainfall zone (HRZ) as part of the GRDC's Soil Biology Initiative...

A team of 90 researchers working on 15 projects aim to increase yields and reduce input costs in soils across the high-rainfall zone (HRZ) as part of the GRDC's Soil Biology Initiative... The research into disease suppressive soil focuses on the following areas: the physical, chemical and biological features of disease suppressive soils, and whether they are regionally specific; determining whether disease suppression in soils is a temporal phenomenon and whether it targets specific pathogens' potential development of a disease suppression index based on the genetic signature of a soil community; and management of the crop-soil ecosystem, including the physical and chemical environments, to increase disease suppression...

Soils that are able to withstand or reduce the extent of crop damage from a soil-borne disease incursion are referred to as disease suppressive soils... While the soils have been identified in all grain production regions little is known about the soil bioogy that confers disease suppressive qualities on a soil... The development of new tools to monitor disease suppressive soils will ultimately benefit farmers by allowing management practices to be linked to transferring or improving disease suppressiveness in soils...

SBI-II researchers from across Australia met more than 60 WA growers and advisers from Geraldton to Ravensthorpe to gain insights into the factors driving on-farm soil biology decisions and how soil biology fits into a whole-farm context... Associate Professor Pauline Mele, of the SBI-II and the Victorian Department of Environment and Primary Industries, says collaboration between scientists and growers is vital to exchange ideas, observations and concerns about soil biology... "Hot topics arising during the tour included: non-wetting soils and the role of soil biota in improvements; carbon storage and loss; and the impacts of pesticides and fertilisers on the resilience of soils," she says...

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...
