A new report outlines actions taken by the Grains Research and Development Corporation (GRDC) in response to local priority issues identified by Western Australian grain growers... The GRDC's 2014-15 Regional Cropping Solutions Networks (RCSNs) Annual Report provides a summary of recent activities initiated by WA's five RCSNs, and an overview of the GRDC's investment planning process for grains research, development and extension (RD&E)... High priority issues identified in 2014-15 by WA RCSNs include profitable rotations; subsoil constraints; acidity; herbicide resistance; nematodes and soil-borne diseases; canola and the need for better agronomic packages for this crop; frost; non-wetting soils; management of seasonal and soil variability; and business management...

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...

" Over The Fence West: Weeds and non-wetting soils issues of the past for Candeloros 04 April 2014 Weeds and non-wetting soils are fast becoming issues of the past for the Candeloro family at Toodyay in Western Australia thanks to a "fluke" decision to try moulboard ploughing five years ago... The family, made up of Joe and wife Maria and their three sons and partners, first tried the technique on their farm due to its low cost -- the results have exceeded their expectations...

Clay and spading helps rebuild non-wetting soils.. On 19 July 2010, after about 78mm of rain, the nil treatment (Figure 1) had a lower plant density and went on to yield 0.66t/ha, while the 260t/ha of clay incorporated by spading plot (Figure 2) had a high plant density and went on to yield 1.41t/ha... In 2010 Trevor had electromagnetic surveys (EM38), gamma-ray spectrometry (radiometrics) and deep soil analysis done for measuring and mapping the depth to clay and he used these maps in 2011 to strictly apply clay only where it was needed...

He estimates 90 per cent of the 2400 hectares he uses for cropping on his farm does not wet-up on the surface (0 to 10-centimetre layer) during the growing season unless there is a major rain event... Benefits of claying "On the treated areas, we have probably doubled our crop yields in favourable seasons - although seasonal variation makes it hard to gauge what the actual gains have been," Clint says... Clint says a major benefit of claying is that weeds germinate in a tighter period in the first year, allowing an effective first knockdown herbicide application...

Yields climb as clay lessons learned.. Using a tracked tractor for added traction, John and Stewart hope to treat at least 50ha a year, but they are aware they may need to hire a contractor to incorporate the clay with a spader... "Adding clay to the topsoil by spreading or delving is really helping to improve the structure of our soils," John says...

Primary Industries and Regions South Australia (PIRSA) soil and land management consultant David Davenport, from the department's Rural Solutions SA division, says there are at least one million hectares of land in SA alone that would benefit from amelioration of sandy soils... "Sandy soils have several known constraints including water repellence, compaction, low fertility and low water-holding capacity," he says... Mr Davenport says there are a range of different amelioration options that growers can use to overcome one or more of these constraints including spading, deep nutrition, incorporation of organic matter and the addition of clay...
