A one-day workshop, with 58 participants (Appendix) and sponsored by the New Zealand Society of Soil Science, was held at Lincoln on Thursday 1st March 2012. The aims of the workshop were: To current research and opportunities for future soils research with respect to irrigation in Canterbury To bring soils researchers and industry representatives with irrigation expertise together to enable networking discussions. During the day there were 27 presentations, each of 5 minutes duration,

Do we understand the soil processes to allow sustainable land management under irrigation? The large number of presentations highlighted that there is a good level of active soil research related to irrigation, across a range of organisations. There is also breadth in this research, ranging from landscape-scale analyses of irrigation schemes, to paddock-scale management technologies, down to processes driving nitrogen and microbe leaching. Following each presentation theme there was a discussion forum to identify the general state of knowledge, with topics assigned to one of three categories: agreed, debated, and gaps. All results are presented in this report. Overall participants agreed most about the current knowledge status in themes two and three, with considerably less agreement about current knowledge at the landscape scale (theme one). Greatest debate took place within themes one & two, with a lot of research gaps identified across all three themes. Some of the knowledge gaps that were repeatedly identified included: There is still a need to better understand the fate of both water and nutrients in the environment. Our current knowledge of shallow and stony soils commonly was considered inadequate. There is a need for improved understanding of soil physical changes under irrigated conditions. Systems modeling was seen as important and a [...]
