Based on the data, a number of biochars will be selected for detailed field and laboratory-based experiments to assess the different aspects of the biochar on crop nutrition and associated soil properties... The project (in collaboration with project CSO00041, Evelyn Krull CSIRO) uses a combination of fundamental and applied experiments to assess the potential fit of biochar into current and future farming systems with a particular focus on plant nutrient acquisition... 4) A web-calculator to assess the effect of biochar on crop productivity Research iIn conjunction with the DAFF national biochar initiative, the project team assembled over 80 different biochars (from different sources and produced under different temperature regimes) which have been analysed for various functions, such as C content, pH, CEC, adsorption capacity, stability, water-holding capacity, porosity and specific surface area...

As a consequence of the project UA00060, vital information has been obtained on the seedbank ecology and population dynamics of brome in response to various management strategies developed through on-farm research... Results from the survey of grower paddocks on Yorke (YP) and Eyre Peninsulas (EP) in South Australia (SA) confirmed the species of brome grass infesting cereal crops of southern Australia as Bromus diandrus and Bromus rigidus ... Several studies were undertaken at Roseworthy to investigate the germination behaviour of different populations of brome grass ( B. diandrus and B. rigidus ) collected from sites on YP and EP. Clear differences were shown between species, with populations of B. diandrus germinating at a much faster rate than its close relative, B. rigidus ...

Studies have revealed that growing crop legumes in rotation with cereals can often reduce the need for nitrogen fertiliser inputs by 40 to 80 kilograms per hectare, and improve crop productivity... Basic principles and practical management information relating to nitrogen fixation by crop legumes is contained in a new fact sheet released by the Grains Research and Development Corporation (GRDC)... The ability of legumes to form a mutually beneficial association with rhizobia and fix atmospheric nitrogen gas enables them to grow in almost any soil without nitrogen fertiliser...

A new web-based diagnostic tool to assist agronomists in identifying and managing cropping constraints was unveiled today... "CropPro delivers diagnostic and economic tools for efficient identification and management of constraints to crop productivity," Dr Pittock says... Caption: CropPro has been designed to assist agronomists to identify specific crop constraints, or short list likely constraints, based on agronomic observations...

Timeliness of farm practices has been an important consideration for Dr Hamilton over the years in his roles as agricultural consultant, grain grower and now Grains Research and Development Corporation (GRDC) northern panel member... "Research is showing that the single greatest impact on crop productivity is timing of management practices in areas like sowing, weed control, fertiliser application, pest and disease management," Dr Hamilton said... "There's also research being done which assesses the advantages of on-farm drying in summer rainfall areas to allow earlier harvest and minimise the risk of weather damaged grain; the merits of dry sowing to enable canola and cereals to be sown in the optimal window; and the impact of timely in-crop fungicide and herbicide sprays on crop productivity," Dr Hamilton said...

"By visiting the GRDC site, growers can hear first-hand about some of the research projects that are helping drive yield improvement in northern farming systems," Ms O'Keeffe said... "The GRDC will be onsite at 887 and 888 for the duration of Henty and we welcome growers to drop in to discuss any relevant research, development or production issues or attain advice on the use of GRDC's range of GrowNotes, apps or other extension initiatives.".. The boundary revision coincided with the appointment of a new northern panel which provides an effective link between growers, the research community and GRDC and plays an important advisory and strategic role in GRDC investments across the research, development and extension spectrum...
