Growers in WA are using powerful deep-ripper implements to break through hardpans and allow plant roots and nutrients to reach deeper, more productive depths.. Trials were undertaken at three sites using various types of rippers and configurations for depth and spacing, including machinery depths to 20, 30 and 40 centimetres and tyne spacings of 30 and 60cm... "The results reinforce the importance of doing small plot trials before applying extreme treatments across paddocks, as well as knowing the characteristics of the subsoil and using an experienced machinery operator - to minimise the risks of negative impacts such as bringing too much clay or rock to the surface," she says...

Research explores forest gravel water repellence.. Forest gravel soils often have a high percentage of gravel in the topsoil and a sandy or loamy matrix.. With GRDC funding, Department of Agriculture and Food, Western Australia (DAFWA) researchers are investigating the most suitable short-term mitigation and longer-term amelioration tactics to manage water repellence, improve crop nutrition - especially phosphorus availability - and lift the productivity of these forest gravels...

" Managing nutrition on soils that have been treated for water repellence by cultivation.. A comparison of N uptake at 10 N and 50 N showed significant increases in N uptake in the nil and banded wetter though not in mouldboard and spading... The results suggest that soil nitrogen is more available in the mouldboard and spading treatments than in the nil and banded wetter...

A range of one-year trials investigating non-wetting soils are underway in the western part of the Kwinana port zone after receiving funding from the GRDC. Image: A crop planted in non-wetting soil... "The networks were established under the Rural Cropping Solutions (RCS) initiative, which is part of a renewed effort by the GRDC to reduce the time it takes for new varieties, practices and technologies to be adopted, with the ultimate aim being to increase the profitability of the Australian grains industry," he says... Mr Roberts says the trials resulted from the Kwinana west RCSN calling for expressions of interest from groups or individuals to apply for funding through the GRDC...

The project will link and integrate with another project on non-wetting soils 'Delivering agronomic strategies for water repellent soils in Western Australia' led by Dr Stephen Davies at DAFWA... The main focus of this project "Novel solutions for managing non-wetting soils", is to explore managements that promote water infiltration into non-wetting soils and increase crop production and profitability... At the beginning of the project a review will be done of current knowledge on strategies to manage non-wetting soils, including published research reports, grower knowledge and unpublished DAFWA reports...

Five, one-year trials investigating non-wetting soils, and management tools to address them, are taking place in the western part of the Kwinana port zone after receiving funding from the GRDC... "The networks were established under the Rural Cropping Solutions (RCS) initiative, which is part of a renewed effort by the GRDC to reduce the time it takes for new varieties, practices and technologies to be adopted, with the ultimate aim being to increase the profitability of the Australian grains industry," he said... Mr Roberts said the WA RCSNs had applied to the GRDC for funding for other small projects addressing local agronomic priorities, and decisions on a number of these applications were pending...

On-row sowing may significantly benefit crop emergence during drier seeding conditions, although yield benefits have not been measured in Western Australian field trials... Canola emergence from on-row sowing, left, compared with inter-row sowing, right, during a previous season on the farm of Steve Waters, Calingiri, pictured centre with staff from CSIRO Agriculture... On-row sowing is when crops are sown immediately alongside or within the previous crop row, compared with inter-row sowing in which crops are sown in between the old crop rows...
