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..

Activity 1: Estimation of the actual amount of N fixed: In Australia, most estimates of FL-N fixation were determined using indirect methods, e.g. N balance estimates or nitrogenase activity measurements using acetylene reduction assay... While the estimates provide an indication of N fixation potential, they do not provide direct estimates of N fixed... Estimation of the actual amount of N fixed quantify the amount of N fixed - Acombination of 15N isotope tracer methodology and biochemical methods are being standardized to quanity the amount of 15N fixed using soils from South Australia (Calcorosol, Alfisol, Vertisol) and Western Australia (Sodosol)...

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...

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)...

Disease suppression is the ability of a soil to suppress disease incidence or severity even in the presence of the pathogen, host plant and favourable environmental conditions... Soil selected for their suppressiveness tor fungal diseases from southern Australian will also be assessed for their ability to suppress root-lesion nematodes... Soil selected for their suppressiveness to fungal diseases from southern Australian will also be assessed for their ability to suppress root-lesion nematodes...
