Mouldboard ploughing could help lift yields in sandy soils.. Trials in WA show mechanical soil inversion could reduce soil constraints and herbicide-resistant weeds in sandy soils By Nicole Baxter Key points Researchers say inverting sandplain soils using a mouldboard plough or rotary spader once every 10 to 15 years could help manage 'hostile' subsoils, non-wetting sands and herbicide-resistant weeds... Dr Davies says deep-ripping to remove compaction resulted in similar increases in productivity, but the added benefits of mouldboard ploughing include improved weed control, reduced soil water repellence and an opportunity to increase soil pH through lime incorporation...

Strategic cultivation shows on-farm profit potential.. When the Hamiltons - Rodney and his son Sam - started hosting the trials on their 4046-hectare property in 2012, they were sceptical that ploughing the soil would not undermine the long-term benefits of no-till, which have seen increased yields and a lift in overall profitability... A recent survey of 55 growers and advisers in the northern grain-growing region showed that no-till systems have higher weed and disease pressure than farming systems where tillage is used...

Twelve years of monitoring 30 commercial cropping paddocks containing herbicide-resistant annual ryegrass ( Lolium rigidum ) has convinced Australian Herbicide Resistance Initiative communications manager Peter Newman that an integrated weed management approach is the only way to get on top of herbicide resistance... "Put simply, growers should use a combination of herbicide and non-herbicide weed control for long-term success," he said... Mr Newman said that when growers focused on holistically managing herbicide-resistant annual ryegrass, they achieved a 98 per cent reduction in ryegrass numbers over 12 years...

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...

New GRDC research tackles return to tillage.. Dr Yash Dang, Department of Science, Information Technology, Innovation and the Arts (DSITIA) says many grain growers are resorting to cultivation to manage problem grass weeds... Chemical: soil carbon status (including fractionating soil carbon into pools with differing lability), profile mineral nitrogen and potentially mineralisable nitrogen in labile organic fractions, phosphorus, potassium and zinc, and crop nitrogen and phosphorus uptake...

The impact of tillage varies with the tillage implement used: inversion tillage using a mouldboard plough, as pictured results in greater impacts than using a chisel or disc plough... The approach enabled eight treatments and 32 plots derived from the original trial, which is allowing researchers to assess the impacts of strategic tillage... More research is required to understand the impact of strategic tillage practices on beneficial root zone microbes and the effect of soil disease suppression...
