Cotton production in Australia has traditionally been conducted using surface irrigation techniques on heavy clay soils. However, increasing pressures on water availability, the potential yield benefits of improved control of soil/water in the root zone, and the potential for reduced labour, fertiliser and pesticide costs has raised grower interest in alternative irrigation application techniques including large mobile irrigation machines. While less than 4% of the total Australian cotton crop is currently grown using large mobile irrigation machines, it seems likely that this proportion will increase due to existing and future pressure on water availability and environmental sustainability as well as economic and political factors. This document reports the findings from a survey of cotton growers irrigating with centre pivot or lateral move machines as well as equipment manufacturers and dealers of these machines. The survey included 25 face-to-face interviews and 6 telephone interviews with growers as well as interviews with the major manufacturers and dealers within the industry,
