The diverse nature of NPSI investments is shown in two final reports which have just been completed. One concerns research into use of oxygation as a technique on various Queensland crops, while the other has an extension focus for WA vegetable growers.
Optimising delivery and benefits of aerated irrigation water
(Professor David Midmore and Dr Surya Bhattarai, University of Central Queensland).
The work undertaken in this project has added to the scientific understanding of how aerated water can make a positive difference to water, soil and plant root interactions. There have also been field experiments which have improved air-injection techniques that have incorporated practical experiences of primary producers. Download report.
Up-skilling water managers on expert irrigation systems
(vegetablesWA Policy and Program Manager John Shannon and extension officers).
Funding of this project has allowed extension of the Vegetable Irrigation Scheduling System through case studies and information sharing. The system combines readily available information (e.g. weather forecasts that can be downloaded), as well as local measurements of such things as temperature, evaporation, wind speed, soil moisture, moisture distribution patterns and crop growth stages.
