Water infiltration

Catalogue: Broadacre Field Crops DAFF QLD
The optimum planting time for forage oats is from mid-March to June in southern Queensland, and early April to June in central Queensland... Late planting will hasten maturity and reduce the potential for multiple grazing... Starter fertiliser at sowing is recommended, but should be applied separate to the seed as the fertiliser can damage the seed and reduce its germination (e.g. DAP at 100 kg/ha will provide sufficient nitrogen (N) for establishment and phosphorus for the duration of the crop)...

SARDI's Dr Alan McKay says take-all is the disease likely to catch growers out... Inoculum levels are the highest in more than a decade and growers and advisers managing intensive cereal or cereal/pasture rotations should plan ahead to avoid yield loss later in the season... "If the paddock must be sown to a cereal, then consider barley because any yield losses will be only half that of wheat's potential losses, but inoculum levels will continue to increase."..

Variable-rate technology has enabled Kym l'Anson to both even out and lift wheat yields across a mix of soil types.. Using a blanket rate of gypsum would have wasted over 1000 tonnes of gypsum and lime," Kym says... "We need to keep monitoring the soil to assess whether we have raised the pH sufficiently or if it is acidifying under our continuous cropping program," says Kym...

Soil microrganisms also impact on the physical properties of soils including their capacity to hold water... An on-going output will be the coordination of review workshops and reporting processes to ensure that adequate resourcing, integration and consistency measures are being applied across all projects and new opportunities are identified... The major foci of this project are to screen and identify elite diseasesuppressive microbes for cereals and nodulation enhancing beneficial microbes for legumes...

" Delivering agronomic strategies for water repellent soils in WA.. Existing agronomic options are available to manage water repellent soils including furrow sowing, use of soil wetters, spreading and incorporation of clay rich subsoil and alternative land use options... 3) An extension program designed to empower growers and grower groups to identify the severity of non-wetting soils, the likely impact on grain yield, and the profitability of management strategies including an assessment of the drivers, barriers and extent of grower practice change...

Farmers see pH as a influencer of yield and test and manage soils ... Overall, farmers lack skills/confidence to have a go - and don't know a "trusted someone" to get advice from... This season he had a delver made and he now contracts himself out to farmers...

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...

The expression of water repellency under different tillage and stubble managements was evaluated to investigate anecdotal evidence that repellency disappears under zero-tillage and stubble retention... The results highlight the importance of evaluating water infiltration in the field to take into account not just the physical repellency of the soil, but to include all possible mechanisms of water entry... The results highlight the importance of evaluating water infiltration in the field and not just relying on laboratory measures of water repellency...
