Abstract
Acid soils and soil acidification is a major soil constraint impacting on the productivity and sustainability of agriculture across many regions of Australia. In Western Australia one-third of the soils are acid or at high risk from acidification (pHCaCl2?≤?5). While the application of lime has been demonstrated to be an effective means of neutralising soil acidity in this environment, yield responses vary and are often not immediate, thus impacting on the cost effectiveness of treatment. We have carried out a preliminary analysis of data from lime trials conducted in the wheatbelt of WA to examine the main factors that drive the variability of the response to liming across seasons, environments and management. The analysis to date indicates the potential to move beyond the „on-average‟ responses when talking about the response of crops to liming and provide a basis for more specific recommendations to farmers.
