The contributing factors to soil acidification under the current farming systems are well understood, as are the best practice management systems... For such change in practice to be achieved a whole of industry approach is required and this project will combine a reference committee, on-going education, extension and training of key private and government advisors/consultants who will then support growers into the future... The group will be asked to revisit the major barriers to adoption of liming by growers and propose solutions to overcome them while at the same time consider additional challenges posed by the desired doubling of lime use...

The reliability and economics of deep-ripping with lime incorporation are being studied by the West Midlands Group... Long-term WA research has consistently shown that lime most effectively arrests subsurface acidity (low pH) and lifts crop yields when applied to a depth of at least 30 centimetres and strictly adheres to soil test data... Mechanically incorporating lime deeper into the soil profile will dissolve the lime more rapidly when it contacts the acid soil layer "Larger slots behind the deep-ripping tynes will hold the slot open for longer and deliberately direct the flow of loose limed topsoil into the slot," he says...

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...

Subsoil acidity is becoming a real problem on many scrub soils and may be constraining plant growth... Toxicities of aluminium and/or manganese can reduce plant growth in acid soils... The rates of acidification in any soil type can be minimised by replacing the basic nutrients removed in crop produce (e.g. calcium, magnesium and potassium) as part of a fertiliser program, and by minimising the losses of soil nitrate by leaching via appropriate rotations of legume and cereal grain crops...

The calculator allows growers to either enter their own costs and predictions of yield loss with no lime, or use suggested values from yield response curves to calculate the profitability of undertaking a liming program The calculator also estimates the quantity of lime required to recover soil pH to target levels and the maintenance lime required to counter ongoing acidification due to product removal, fertiliser use and nitrogen leaching... Data from trials near Moora and Kellerberrin with various rates of top-dressed lime (three replicates) are discussed... We have estimated that 2.5 million tonnes of lime is required each year for the next ten years to recover soil pH and address ongoing soil acidification...

Soil acidity remains a major constraint to productivity in the WA wheatbelt... The use of agricultural lime is increasing but, overall, application remains well below the amount required to achieve recommended targets for soil pH... We have estimated that 2.5 million tonnes of lime is required each year for the next ten years to recover soil pH and address ongoing soil acidification...
