Growers need monitoring tools that directly measure soil biology (or provide a reasonable surrogate measure) so they know they are heading in the right direction with their systems and practices... As part of the www.soilquality.org.au monitoring program growers can access regionally specific data on soil biological, chemical and physical constraints to production... The soil quality data on the web site is supported with information fact sheets and calculators which enable 'what if' scenarios to be tested so as to highlight favourable soil quality management decisions...

Soil quality is currently being measured in grain-producing areas across Australia... A selection of the biological, chemical and physical indicators of soil quality measured as part of the Monitoring Program, are shown in Table 1, which also lists how each indicator can be related to soil quality and production... The information on the website is provided in a number of formats including a 'traffic light' snap shot where each measure of soil quality is partitioned into ranges that are assigned green, amber and red status...

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)...

Check up on soil health with a quick click The health and quality of South Australian cropping soils is being benchmarked through an innovative online resource... The website, www.soilquality.org.au , enables growers to compare the condition of their soils with that of their regional farming counterparts... In officially launching the SA node of the website, Dr Murray Unkovich, from the University of Adelaide's School of Agriculture Food and Wine, said development of the online tool had been strongly supported by the GRDC which recognised the importance of comparative data in informing growers about the status of their soils.

Living organisms play a vital role in soil management and should be encouraged.. Bacteria, fungi, nematodes and worms are just a handful of the soil organisms that, when managed correctly, contribute to healthier crops, a leading Canadian rhizosphere ecologist has explained to WA growers... [Photo (left) by Brendon Cant: Canadian rhizosphere ecologist Dr Jill Clapperton.] "Soil microbial life is necessary to improve soil structure, soil softness or tilth and productivity, and plants can better use nutrients from biological processes than chemical fertilisers," Dr Clapperton said...

Increasing the soil organic matter content of soils takes time and requires higher levels of carbon inputs and reduced levels of carbon outputs... The research undertaken by Clive Kirkby (CSIRO) and farmer demonstration projects are investigating management practices which can result in an increase in the humus fraction of the total SOM pool... Soil with Carbon increase of 0.8% had the lowest increase for lowest probability at approximately 4000kg/ha...

Gross margins achieved on-farm for wheat in 2011 may have been lower than shown in Table 2... The gross margin calculations depicted in Figure 5 assumed that canola yielded 50 % of wheat at that site in that year... In comparing while many farm decisions are made intuitive versus logical analytical under the influence of a DSS which provide learning reasoning he suggests the either/or approach to on a topic, they are not necessarily used every time the dichotomies is destructive and goes on to say a decision is made...
