Research interests

Mark's research focuses on understanding and manipulating crop and environmental interactions to deliver improved resource use efficiency, crop productivity and quality of fresh produce. Understanding how crops respond and adapt to, and recover from, short- and longer-term abiotic stresses is fundamental to improving crop productivity in changeable environments. New water and fertiliser-saving irrigation strategies, derived from a detailed understanding of plant response to soil water stress and nutrient deficiency are being developed for several sectors, including soft and tree fruit. Enhancing yield and quality attributes such as flavour volatiles, bioactive content and shelf-life potential using novel deficit irrigation techniques is a key component of this work. The potential to use stress preconditioning to improve crop resilience to abiotic and biotic stresses is also being tested.

A major focus of his research is the development and integration of precision irrigation and fertigation systems into commercial production to help improve on-farm resource use efficiency, plant productivity and consistency of produce quality. In tandem, innovative imaging and sensor systems are being developed to ease the integration of these low-input approaches into commercial practice, so that consistency of cropping, plant productivity, and crop responses to abiotic and biotic stresses can be monitored and measured in real time to inform and improve on-farm decision making.
