| Abstract | Irrigation control strategies that consider infield spatial variability can lead to improved crop productivity and water use efficiencies. The irrigation control approach that optimises crop and water productivity is expected to depend on the variability of irrigation infiltration and soil and plant properties within specific fields. Field data collected in 2013/14 was combined with a simulation study to determine the spatial and temporal data requirements for site-specific irrigation, relative to the amount of infield variability. This paper presents an exploration of the number of data points/furrows to monitor irrigation application, soil moisture, plant growth and fruit load to control irrigation application and optimise productivity. |
