"In preliminary glasshouse and field trials, we have found that acacias inoculated with beneficial strains of a nitrogenfixing bacteria called Bradyrhizobium survive better and grow faster than un-inoculated acacias," Dr Thrall says... Of particular interest is the extent to which re-introduction of beneficial organisms helps plants to withstand environmental stresses like soil salinity and competition with exotic weeds...

Experimentation will focus on molecular techniques to understand the activity of soil microbial communities in releasing nutrients, coupled with detailed measures of soil nutrient cycling... Molecular techniques to understand the soil microbial communities role in nutrient release will be applied to field experiments to determine whether these soil biological processes can be manipulated through agronomic management to improve the prediction of nutrient cycling and crop productivity... Information from both outputs will be used to evaluate whether the presence and activity of these soil biological communities can be modified by different agricultural practices...

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..

The aim of my studies was to investigate how family farms are surviving in marginal areas and see what research is being done to improve their situations... In our semi-arid environment I believe that cover crops would work to improve the soil by shading and cooling it... Throughout my travels in east Europe, Slovakia, Hungary and Serbia the usual succession practice has been to split the farm up between all children equally...

Soil organic matter contributes to a range of biological, chemical and physical properties of soil and is essential for soil health... Soils rarely reach their theoretical potential for organic matter storage (see Figure 1.7)... In soils with low clay content the amount of humus and resistant soil organic matter is increasingly important to nutrient exchange because its large surface area gathers (adsorbs) cations from the soil solution, holding nutrients that would otherwise leach...
