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...

A high proportion of phosphorus applied to these soils can remain inaccessible to crops... Phosphorus derived from the fluid form occupies a larger volume of soil surrounding the fertiliser, which increases the likelihood that roots will come into contact with the nutrient... Shoot response of wheat to fluid fertilisers (APP and H 3 PO 4 ) compared to granular fertiliser (Triple P) and a control growing on a Vertosol collected from Minyip in the Wimmera under glasshouse conditions...

Chickpeas grown in rotation with wheat have become a valuable part of the Swaffer family's cropping program in Central Queensland.. The trial results have encouraged Brendon to increase phosphorus rates to boost yield potential... The PBA Pistol chickpeas yielded 1.6 tonnes per hectare on average, whereas the Kyabra chickpeas yielded 2.2t/ha, he says...

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...

Grower group road-tests subsoil phosphorus nutrition.. The conventional practice of applying 8.7kg/ha of phosphorus in 40kg/ha of starter fertiliser with the seed, about 5cm into the soil, provided a 47 per cent yield increase - almost half the yield benefit of deep phosphorus applications... Preliminary data from the 2014 trials also suggests that subsoil applications of phosphorus at higher rates may provide almost twice the yield benefit of phosphorus applied at low rates near the surface as starter fertiliser...

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...

Paddock records help: establish realistic target grain yield/protein levels prior to planting modify target yield/protein levels based on previous crop performance, planting soil moisture, planting time, fallow conditions, expected in-crop seasonal conditions and grain quality requirements determine appropriate fertiliser type, rate and application method compare expected with actual performance per paddock and modify fertiliser strategies to optimise future yield/protein levels... Valuable information obtainable from a soil test includes current nutrient status, acidity or alkalinity (pH), soil salinity (Electrical Conductivity (EC)) and sodicity (Exchangeable Sodium Percentage (E)), which can affect soil structure... Water volumes of 800-1 000 L/ha were commonly applied...
