The Bourke region has experienced a dramatic expansion of irrigated agriculture, especially cotton production, over the last decade. For sustainable agricultural production, quantitative soil information is required for effective land management and environmental planning. There is therefore the need for updating the soil resource information of the region. Soil sodicity and structural stability are two soil quality indicators specifically investigated in this study. The study is aimed to assess the current levels of soil sodicity and aggregate stability in order to predict spatial patterns of these soil attributes with the view of identifying the risk zones. The effect of land use on the soil quality indicators is examined.
