AI in agriculture: hybrid machine learning models for nitrogen simulation. Agricultural simulation models are used to guide nitrogen management to reduce nitrogen loss and its environmental impact, but they were developed using constrained datasets, which restricts them to site- or regional-specific simulations. This project adopts a novel approach to addressing these problems by applying machine learning-based data analytics.

Agricultural simulation models are used to guide nitrogen management to reduce nitrogen loss and its environmental impact, but they were developed using constrained datasets, which restricts them to site- or regional-specific simulations. This project adopts a novel approach to addressing these problems by applying machine learning-based data analytics. The project will refine the linkages between nitrogen losses and their key drivers, and improve the existing agroecosystem models through data imputation, parameter optimisation and module enhancement. The outcomes of this project will lead to an accurate prediction of nitrogen losses from agriculture, advancement in agroecosystem models and their adaptability to a global context.Read moreRead less

Plasma driven electrochemical synthesis of urea. Urea is the most used nitrogen fertilizer in the world, with more urea manufactured by mass than any other organic chemical. However, the world is experiencing a major shortage of the compound, impacting our food costs and security along with dependent products such as AdBlue (diesel exhaust fluid). Commercial urea production relies on a complex reaction between ammonia and carbon dioxide at high temperatures, which consumes more than 2% of the w ....Plasma driven electrochemical synthesis of urea. Urea is the most used nitrogen fertilizer in the world, with more urea manufactured by mass than any other organic chemical. However, the world is experiencing a major shortage of the compound, impacting our food costs and security along with dependent products such as AdBlue (diesel exhaust fluid). Commercial urea production relies on a complex reaction between ammonia and carbon dioxide at high temperatures, which consumes more than 2% of the world’s energy. This project aims to produce more sustainable urea driven by electricity and using air and captured CO2, through the use of a plasma-driven electrochemical technology, providing farmers with a low-cost fertilizer under a decentralized and secure supply.

Engineered clay-polysaccharide composites for efficient nutrient delivery. Nitrogen (N) nutrient use efficiency of most arable crops in Australian soils is low, leading to excessive application of this nutrient. The low N use efficiency is attributed to its loss through leaching and gaseous emission, which contributes to both economic burden of the farming community and also results in environmental degradation.
