Understanding reaction products of granular and fluid P fertilisers in Australian soils: a way to enhance fertiliser efficiency. Despite posing significant challenges for crop P nutrition, alkaline soils are widespread in Australia and their agricultural use accounts for a significant fraction of the crop production nationwide.

Despite posing significant challenges for crop P nutrition, alkaline soils are widespread in Australia and their agricultural use accounts for a significant fraction of the crop production nationwide. The benefits of fluid fertilizers over conventional granular products in these soils has been agronomically demonstrated. Knowledge of the behaviour of these products, provided through an understanding of the fundamental mechanisms and reactions occurring, is critical to improve crop productivity. This project aims to study the reactions of fluid and granular fertilizers in soils using advanced spectroscopic and isotopic techniques, in order to provide a scientific basis for improving formulations and effectiveness.Read moreRead less
Aggregate structure of humic organic matter. Soil aquatic organic matter is important in plant growth, nutrient supply and water quality and in affecting pollutants and metal ions in the environment.

Australian clays as raw materials of slow-release phosphate fertiliser. Phosphorus (P) fertiliser input in Australia is a significant problem for its inefficient plant uptake, leaching to natural water bodies and stocking of insoluble P in soil.

Phosphorus (P) fertiliser input in Australia is a significant problem for its inefficient plant uptake, leaching to natural water bodies and stocking of insoluble P in soil. The project aims to develop activated clays using Australian raw clay minerals to formulate effective slow-release phosphate (P) fertilisers (SRF) and delivery material for P-solubilising bacteria. Composite of these will supply P controllably even amid environmental fluctuations but when a plant needs as it grows. Development of multifunctional, nontoxic and plant growth-driven P fertiliser would benefit improve soil fertility in a sustainable way where efficiency of P input is maximised with a minimised environmental burden.Read moreRead less
Multi-scale Process Modelling for Intelligent Control. Processing and manufacturing systems are inherently multi-scale in their behaviour. From the molecular scale to the enterprise-wide scale. This and other attributes of the individual models create difficulties in the design and control of such systems.

More efficient and effective fertilizer formulations are needed to improve nutrient use efficiency in agricultural systems globally, and for effective biofortification of staple food crops with essential micronutrients. Nitrogen may be lost from soil through leaching and gaseous losses to the atmosphere. Phosphorus, as well as copper, manganese and zinc, are prone to reactions in soils and during manufacturing which reduces their effectiveness.Read moreRead less
