Understanding reaction products of granular and fluid P fertilisers in Australian soils: a way to enhance fertiliser efficiency

尽管对作物磷营养构成了巨大的挑战，但碱性土壤在澳大利亚很普遍，其农业用途占全国作物产量的很大一部分。在这些土壤中，液体肥料比传统颗粒肥料的好处已经得到了农学上的证明。通过了解发生的基本机制和反应来了解这些产品的行为，对于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液体肥料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。

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.
