This project will develop a state-of-the-art precision irrigation system for optimising water use and crop yield. Specifically, a novel UAV soil moisture mapping system based on passive microwave satellite remote sensing technology at L-band will be developed for near-surface soil moisture mapping at accuracies and spatial scales currently not attainable. These soil moisture maps will then be merged with irrigation water delivery models to calibrate for spatial variation in soil properties and/or correct errors in spatial variation of rainfall and evapotranspiration inputs. Ultimately the water balance predictions will be used for implementation of variable rate irrigation control at scales hitherto unattainable.

该项目将开发最先进的精准灌溉系统，以优化用水和作物产量。具体来说，将开发一种基于L波段被动微波卫星遥感技术的新型无人机土壤湿度测绘系统，用于以目前无法达到的精度和空间尺度进行近地表土壤湿度测绘。然后，这些土壤湿度图将与灌溉水输送模型合并，以校准土壤特性的空间变化和/或纠正降雨和蒸散输入的空间变化的误差。最终，水平衡预测将用于实施迄今为止无法实现的可变流量灌溉控制。
