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.

尽管对作物磷营养构成了重大挑战，但碱性土壤在澳大利亚广泛存在，其农业用途占全国作物生产的很大一部分。在这些土壤中，流体肥料比传统颗粒产品的好处已得到农艺学证明。通过了解发生的基本机制和反应，了解这些产品的行为，对提高作物生产力至关重要。本项目旨在利用先进的光谱和同位素技术研究流体和颗粒肥料在土壤中的反应，为改进配方和有效性提供科学依据。
