Photo of blue dye seeping into soil.. Dr Roper says the trials indicate that the yield gains zero-tillage and stubble retention provid in canola, barley and wheat result from improved water infiltration in the soil... "In our experiments, crops were seeded with discs on the previous year's inter-row, which resulted in no disturbance of remnant root systems from the previous year," Dr Roper says, adding that using this approach with knife points is also unlikely to disturb remnant root systems...

Demise of wet autumns drives new farming system.. John was working in London as an accountant 18 years ago when the phone call came through from his father, a farmer from the wheatbelt at Piawaning... John has experimented with a number of solutions, with some success: "There's claying, which involves finding suitable clay in the area, digging it up, spreading and incorporating it into the surface," he says.

Trials of mouldboard ploughing to alleviate non-wetting soils near Corrigin have produced impressive initial results including high crop yields and low weed numbers in what was a poor performing paddock... The CFIG research is also investigating other options for non-wetting soils including wetting agents, winged points and in-row seeding (as opposed to inter-row seeding) and is one of five RCS non-wetting soils projects in the western part of the Kwinana port zone... Mr Wallwork said the trial results reflected findings from the northern grainbelt which showed that mouldboard ploughing effectively changed the soil type by bringing subsoil to the surface...

Many of the farmers visited during recent 'non-wetting bus tours' are featured in a new GRDC RCSN booklet Combatting non-wetting soils ... Mr Roberts said that along with frost and weeds, non-wetting soils had been identified by the western regional panel and Regional Cropping Solutions Networks (RCSNs) as one of the top three GRDC research, development and extension (RD&E) priorities in WA... Mr Roberts said the RCSNs had recognised that non-wetting was limiting yields and that it was increasing in extent and/or severity across many of the grain growing regions of WA...

GRDC panel members and staff met with growers and researchers across the country to discuss issues they face as part of annual spring panel tours in the southern, western and northern grain-growing regions... GRDC Northern Panel chair, James Clark, says the tour of growers' properties, trial sites and research facilities aimed to overcome obstacles to productivity and profitability at a grassroots level... "There are many ways the GRDC consults with growers and researchers, but standing in crops discussing local production constraints and priorities for GRDC funding gives the panel a clear picture of what needs to be tackled," Mr Clark says...
