" WA surveys in 2012 by the Department of Agriculture and Food (DAFWA), Liebe Group and Farmanco indicate that current lime application falls well below that needed to maintain soil pH levels at the critical minimum levels of 5.5 in the soil surface (0-10cm) or 4.8 in the sub-surface (10-30cm)," he said... Mr Roberts said the soil acidity investment, outlined in the GRDC 2013-14 Investment Plan , aimed to increase grower and adviser confidence in diagnosing acidity limitations to crop growth, as well as increasing lime use... Mr Roberts said all projects in the plan required results to be extended to growers and other stakeholders...

Subsurface acidity is a major constraint to crop and pasture productivity across Western Australia's grainbelt and is estimated to erode potential crop yields by 9 to 12 per cent, worth $500 million annually... About 14.25 million hectares of WA grainbelt soils are acidic or at risk of becoming acidic to the point of restricting crop yields, and lime use has increased in recent years to address acidic soils with low pH levels... Region West < Keep browsing 0 Responses to New resource delves into soil acidity and lime..

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...

Coordinating the improved management of soil acidity in Western Australia and the GRDCSouthern Region... The project will coordinate a national effort to effect a step change in the management of soil acidity in the Western and Southern GRDC regions... Existing and new information including data from lime trials, publications and recommendations will be used to develop or improve a collection of simple calculators which will enable growers to make informed decisions to ensure that they are confident about the management decisions they make including an understanding of the likely outcomes if the levels of soil acidity on their farms is not managed appropriately...
