Soil testing with rake and boot.. Research is updating 'critical soil test values' which is improving interpretation of soil test results and helping Western Australian grain growers make better fertiliser decisions... Findings from crop nutrition research and guidelines to help growers conduct soil testing and apply fertiliser effectively are outlined in a Soil Testing for Crop Nutrition Fact Sheet and More Profit from Crop Nutrition Ground Cover Supplement...

The work will characterise PUE of a diverse range of wheat and barley varieties in the field to identify germplasm with consistently high PUE... The aim of the project is to assess the level of genetic variation in response to phosphorus fertiliser in wheat and barley and to provide plant breeders with the information and genetic tools to improve phosphorus use efficiency of cereals... There are three outputs from this project: (i) it will characterise the response to phosphorus among a large number of varieties of wheat and barley; (ii) it will provide detailed analysis of the reasons why varieties show different response to phosphorus fertiliser and how this relates to their phosphorus use effciency and (iii) through genetic studies it will aim to provide plant breeders with tools to make the selection for phosphorus use effciency easier...

The new age of soil phosphorus testing is.. Extensive testing over recent years and trial analysis this year have demonstrated that the DGT test offers considerable improvement in predicting soil available P levels on many cropping soils in south-eastern Australia... Dr Mason says the DGT test is a plastic device that uses an iron oxide gel as a P sink, which attracts available P through a membrane...

New national initiative to help grain growers adapt to climate change.. Through the Australian Government's climate change initiative, Australia's Farming Future - Climate Change Research Program (CCRP), the Department of Agriculture, Fisheries and Forestry (DAFF) and the Grains Research and Development Corporation (GRDC) have commenced a demonstration program called the National Adaptation and Mitigation Initiative (NAMI)... GRDC Managing Director Peter Reading says the initiative will play an important role in equipping primary producers with tools to adapt and adjust to the impact of climate change and to manage their emissions...

Over the next year, new research will provide Western Australian growers with information to compare the cost effectiveness of purchasing different information layers for variable rate technology (VRT) zone application maps... In addition to a comprehensive literature review, knowledge and experiences from growers, agronomists and precision agriculture practitioners about the benefits and drawbacks of each information layer will be incorporated into the study... "With seeding well underway in the west, decision making about the cost effectiveness of purchasing different map layers for variable rate technology (VRT) zone application will be top of mind for many growers," Mr White said...

For grain growers who thought they were already shovelling out the nitrogen every year, 's a sobering thought... Dr Angus says the rate of decrease appears to be linear over 10 to 30 years but after about 50 years, turns out to be curved and soil N eventually flat-lines... Dr Angus says it is likely that gross margins underestimate the profitability of the mixed pasture-crop system by not accounting for other synergies between pastures and crops...

Studies funded by the Grains Research and Development Corporation (GRDC) are investigating whether crop stubbles offer useful amounts of phosphorus (P) to plants during the growing season... The research is being conducted by the University of Adelaide which plans to develop a better understanding of how P is released from stubble and then taken up by subsequent crops... ENDS Caption: University of Adelaide research student Sarah Noack is involved in a study which plans to develop a better understanding of how P is released from stubble and then taken up by subsequent crops...

The Better Fertiliser Decisions for Crop Nutrition Fact Sheet states that inefficient or incorrect use of fertiliser can be a substantial, but somewhat hidden cost, in the cropping operation... The new fact sheets have been distributed to growers with the November-December issue of GRDC's Ground Cover magazine and can also be viewed and downloaded via www.grdc.com.au/GRDC-FS-BFDCN and www.grdc.com.au/GRDC-FS-CropNutrition-Micronutrients ... Caption: The Grains Research and Development Corporation (GRDC) has released two new fact sheets to enhance grain growers' understanding of crop nutrition...

Soil testing the key to fertiliser savings.. According to the Crop Nutrition Fact Sheet published recently by the Grains Research and Development Corporation (GRDC), results from more than 100,000 recent soil tests in the south-west of WA showed that most growers are operating at or above the soil P levels required... If the tests show that soil P status is sufficient, there may be an opportunity for growers to save money on P fertiliser by cutting back to a maintenance rate...

Photo: GRDC Northern Panellists inspect GRDC-funded winter crop trials in northern NSW... The checklist gives growers a comprehensive 'to do list' that will help growers maximise the potential that each year offers so they will be satisfied when harvest rolls around and yield and protein levels come in... Rotations - top of the list is the selection of crops and varieties as rotations, summer and winter, have become essential to our farming system in terms of controlling weeds and diseases...
