Unlocking Phosphorus Availability Using Biostimulants and Struvite
- Beschreibung
This project focuses on exploring innovative approaches to sustainable nutrient management in agriculture, with a particular emphasis on combining phosphorus-recycled fertilisers, especially struvite, with biostimulants.
Struvite (MgNH₄PO₄·6H₂O) is a slow-release phosphorus source recovered from wastewater streams and is increasingly considered a sustainable alternative to conventional phosphorus fertilisers. However, its effectiveness in soil is largely dependent on its solubility and the physicochemical and biological conditions of the rhizosphere.
In contrast, biostimulants—comprising beneficial microorganisms and bioactive compounds—can enhance nutrient availability through mechanisms such as organic acid exudation, increased enzymatic activity, and improved root development.
The aim of this project is to investigate the interaction between struvite and biostimulants in the rhizosphere and to evaluate their combined effects on phosphorus availability and plant uptake. To achieve this, greenhouse and soil-based experiments will be conducted to compare different treatments (struvite, biostimulant, and their combination).
Students involved in this project will gain hands-on experience in laboratory and greenhouse techniques related to plant nutrition and soil chemistry and will participate in the analysis of plant growth and nutrient dynamics.
This project lies at the interface of soil science, plant physiology, and sustainable agriculture, and contributes to the development of strategies aimed at reducing reliance on conventional fertilisers while improving phosphorus use efficiency.
