Soil phosphorus can be taken up by wheat roots directly or through beneficial arbuscular mycorrhizal fungi (AMF)... Professor Andrew Smith and his team, which includes Professor Sally Smith, Dr Maria Manjarrez-Martinez and Dr Ann McNeill from the University of Adelaide, are using this technique to demonstrate how important the contribution of mycorrhizas is to phosphorus nutrition and whether break crops can be used to maximise AMF populations... The research team established a field experiment at the beginning of this crop season to follow up and quantify the amount of phosphorus transferred by AMF. Results can also be used to measure the contribution of phosphorus uptake by wheat with different fertiliser applications and to inform new breeding strategies...

Fertiliser decisions by grain growers start with and rely on knowing the status of paddocks... Develop National and regional soil test - nutrient response calibrations for assessing the nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) status of soils used for cereal, pulse and oilseed production... BFDC is seeking to improve the confidence of grain growers and advisors using soil testing as a tool for making more accurate fertiliser decisions on farm...

A significant, but preliminary, finding of research carried out as part of this project at the research station Wongan Hills in 2012 found a history of lime application significantly increased soil pH, phosphorus uptake by crops and grain yields... Through the GRDC-funded 'More Profit from Crop Nutrition Initiative' program, Department of Agriculture and Food, Western Australia (DAFWA), researchers found a strong grain yield response to past lime applications and phosphorus uptake in year one of the trials... Researchers found that wheat plant biomass increased and ryegrass biomass dropped in plots where lime had been previously applied and phosphorus rates of five, 10 and 20kg/ha were used...

" Agribusiness Trial Extension Network.. Trial results have been mixed and there has been little investigation regarding the most efficient form of liquid P in cropping systems... There has also been little investigation of the influence of the water application volume used to apply P on the efficiency of P use in NSW. Work by Landmarks Product Development Group in South Australia, Victoria and Southern NSW has shown that the use of higher water rates to deliver liquid P results.....

In mixed farming systems grazing of the pasture phase can be used to minimise weed burdens but for continuous croppers, or within the cropping phase of mixed farming, some tillage might be needed for integrated weed management... From an overall systems perspective, limited and strategically timed tillage could form part of a productive, sustainable system... A central question emerges : How much damage is done to soil by occasional tillage, strategically applied, in an otherwise no-till system We seek to investigate this question based on the hypothesis: That the agronomic and economic benefits of a strategic tillage operation exceed any agronomic costs due to damage to soil structure...

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..
