At a Merredin Research Station field day, DAFWA researchers Dr Abul Hashem (left) and Mohammad Amjad explain the effects of lime on reducing annual ryegrass in a wheat/lupin/barley/barley rotation, four years after application of limesand... Western Australian research is showing that lime application not only helps to overcome soil constraints, but can also diminish weed burdens in low pH wheatbelt soils... The trials found the use of lime to achieve (even small) increases in pH significantly reduced the density of annual ryegrass, barley grass and wild radish in that timeframe...

Bencubbin grain grower Tony Sachse (left) is trialling lime incorporation with a Grizzly offset disc plough to help ameliorate subsoil acidity and aluminium toxicity, assisted by Precision SoilTech research officer Wes Lefroy... Bencubbin grain grower Tony Sachse is trialling aggressive tillage methods to fast-track the movement of lime into acidic and aluminium-toxic subsoils that make up parts of his 9700-hectare property... For most of the 40 years that he has run the family operation with wife Margo - and now son Ben - he has been topdressing lime at a rate of 1 to 1.5 tonnes/ha on these areas every summer...

" Date: 18.01.2016 pH maps cut the cost of tackling soil acidity.. Victorian grower Evan Lewis expects to reduce his expenditure on lime by almost 70 per cent this year through the use of variable-rate technology... Compared with a blanket lime rate of 2.5 tonnes per hectare applied across the Lewis family's property for 13 years, pH mapping will enable Evan to tackle the acidic and sodic imbalance in his soils with lime rates ranging from just 1.2 to 2.1t/ha in 2016...

But scientists such as the Department of Agriculture and Food's (DAFWA) Chris Gazey say that despite these big steps in the right direction, 2.5 million tonnes annually is needed over the next ten years to treat existing and ongoing soil acidity, which costs WA agriculture more than $500 million per year in lost productivity... Mr Gazey, who recently completed a Caring for our Country soil acidity research project, says WA soils are continuing to acidify, with mapping of the State's agricultural soils highlighting the severity and extent of soil acidity, including subsurface acidity... Mr Gazey says other evidence supporting the need for sustained efforts to address soil acidity includes re-evaluation of a 1994 trial site in a Mingenew paddock showing that lime rates previously considered adequate do not ameliorate soil pH at depth...
