Put science behind decisions for farm profitability.. Proficient and timely agronomic management is one of the key drivers of crop profitability and there are a myriad of tools available to help growers make informed choices on crop and varietal selection, crop rotation, plant available water capacity and soil/plant nutrition while managing the risks of pests and diseases... The practical tools are complemented by a wealth of statistical data which is continuously gathered, analysed and interpreted through projects like the Statistics for the Australian Grain Industry (SAGI) project supported by the Grains Research and Development Corporation (GRDC)...

Large group of people standing in line gazing into a crop field.. Growers inspecting Crown Rot Analytical trials at Bellata... A PreDicta B test can be arranged by contacting commercial testing service, Crown Analytical Services, which provides northern growers and advisors with bags, soil corers, protocols and procedures for sampling as well as an interpretation of results once tests are completed by the South Australian Research and Development Institute (SARDI) in Adelaide...

Results from technology that measures soil moisture across the Western Australian grainbelt indicates that nitrogen fertiliser 'top-ups' applied in coming weeks could have variable yield benefits, depending on location... "Analysis of sites hosting new soil moisture probes suggests that potential benefits range from nil to more than 0.5 tonnes per hectare," Precision Agronomics Australia's Frank D'Emden said... " the modelling suggested that responses to top-up nitrogen ranged from nil at the Beacon, Bonnie Rock, Southern Cross and Merredin sites - where soil moisture is marginal - to at least 0.5t/ha at the Coomberdale, Bindi Bindi, Dowerin, Lake Grace and Jerramungup sites - where soil moisture levels are reasonable," he said...

The aim of the following study was to acquire a unique, long-term (> 1 year) data set of N 2O emissions from a rainfed, cropped soil in a semi arid region and to investigate the relationship between N 2O emissions and other soil and environmental parameters... Some ability to make in-season tactical decisions when to graze or continue through to harvest would be valuable... The commodity prices are an important aspect of any decision to graze a cereal crop...

How wet is your soil: Tools for working out plant available water capacity.. "If growers understand how rainfall is captured and stored for future crop production, know their soil characteristics and moisture levels at key times like planting, as well as what tools to use for monitoring it can assist in the decision making... PAWC or size of the soil bucket is determined by the soil type - the proportions of sand, silt and clay, the soil depth and the crop which is being grown...

The target area for this project is located in the N/NE wheatbelt of Western Australia and builds on some of the findings from GRDC project CSP00015 and collaborations with farming groups established as part of that project... The project is designed to impact on different levels within the farming system: the crop, the crop system, and issues at the whole farm level that impinge on crop management decisions... Incorporating a balance of short and long term research questions, this project will improve grower understanding of water use efficiency and the range of management decisions that can alter water use efficiency and productivity in this environment...
