AB  - Improving plant nutrition is key for higher crop yields and could be achieved with environmentally-friendly fertilizers. Phosphorus (P) is especially limiting to plant development, yet, conventional P fertilizers have been increasingly associated with eutrophication of freshwater systems. Struvite (St) is an alternative source for P, recycled from urban wastewaters. Its low water solubility reduces environmental impacts; however, efficiency can be considerably low in granular form for field application. Therefore, fertilizer design plays a critical role that should be addressed. In the present work we prepared slow-release fertilizers based on St fine dispersion in a biodegradable matrix of thermoplastic starch (TPS). Herein, we unveiled P dissolution patterns of St-TPS composites and their effect on maize growth. The results showed the potential of St-TPS to achieve a desirable agronomic efficiency for maize while also reducing P runoff losses in highly permeable or acidic soils.
