Challenge Crop production systems in large controlled environment facilities are traditionally high-input, resource and capital-intensive. Optimising input parameters is a major avenue for increasing yield and quality whilst reducing waste of precious resources. CO2 levels are particularly critical for crop growth and yield, but defining optimal levels in controlled environment cropping systems to manage yield is challenging. Production at sub- and supra-optimal CO2 incur crop yield, economic and environmental penalties.
Solution This project aims to determine the optimal CO₂ concentrations for tomato production in controlled environments. Through systematic trials and monitoring, the research will define CO₂ thresholds that maximise yield and quality while minimising unnecessary input use and environmental impact.
Impact The findings will enable more precise, sustainable CO₂ management in high-tech cropping systems, enhancing productivity and reducing waste. This will support growers in making data-driven decisions, leading to better economic returns and environmental outcomes in controlled environment tomato production.
