Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

To manage the issues, Andrew and Gina Kenny and Andrew's parents Mike and Sara are using a range of short-term mitigation and longer-term amelioration strategies... Andrew says clay incorporation is the most effective amelioration remedy, producing significant crop yield increases where it has been used on about 300ha... "The paired-row seeder effectively has 50 per cent more seeding row, which increases the chances of seed landing in wet soil, and the wings means it potentially grades the water-repellent soil out of the wider furrow better," Andrew says...

Mullewa grower Andrew Messina is trialling a new deep-ripper that can slice 80 centimetres into the soil to crack hard pans and help overcome compaction issues... Andrew says in 12m-wide and 200m-long paddock strip trials on an area that had been mouldboard ploughed in 2011, the deep-rippers produced wheat yields of 2.7 tonnes per hectare, compared with 2t/ha from the nil-treated area and 2.3 to 2.4t/ha from a conventional deep plough (tilling to a depth of 30cm)... Andrew says the main drawback of ripping to depths below 30cm is having to use a much smaller machine - the Heliripper is about 6m wide, travels at a speed of 7 to 8 kilometres per hour and treats about 5ha/hour...

Crop roots push deeper after lime.. Tony White and his family have increased their wheat yields by applying 2.5 to 3.0 tonnes per hectare of lime and then hiring spading and mouldboard ploughing contractors to push the ameliorant into acidic subsoils on their farm near Miling, Western Australia... For the past two seasons, Tony has harvested more grain by doubling his usual rate of lime and using spading and mouldboard ploughing to really drive the ameliorant into the subsoil...

" 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...

Mouldboard plough outperformed spader for weed suppression.. When the weed population was checked in March 2010 after a wet summer, Andrew says the results showed mouldboard ploughing had outperformed spading... The paddocks nominated for mouldboard ploughing are scheduled for the end of the sowing program, the delay allowing time for the opening rains to have thoroughly wet the soil down to 300mm...

Mouldboard ploughing is one option being trialled as an amelioration tactic for overcoming the symptoms of non-wetting soil: poor water-holding capacity, water repellence and acidity... Department of Agriculture and Food, WA (DAFWA) senior research officer David Hall says research is showing mouldboard ploughing can significantly boost yields, and the benefits so far are persisting for several seasons... Owners: Michael (Mic) and Marnie Fels Location: Wittenoom Hills, Western Australia Farm size: 6000 hectares (arable) Enterprise: cropping Rainfall (average annual): 450 millimetres Soil types: transitional mallee and duplex Crops grown 2013: wheat (2000ha), canola (2000ha), barley (2000ha)..

The aim of the study was to determine how mouldboard ploughing (soil inversion), rotary spading and banded wetting agent affect the availability of soil nutrients... Soil moisture and pH were measured on a 5 x 5 cm grid and root maps were taken by marking each root intersection with the pit face on a transparent film... Our results from the first year of the study show that the method used to manage soil water repellence had little impact on soil nutrient supply with the exception of phosphorus...

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...
