dc.descriptionStruvite (St) recovered from wastewaters is a sustainable option for phosphorus (P) recovery and fertilization, whose solubility is low in water and high in environments characterized by a low pH, such as acidic soils. To broaden the use of struvite in the feld, its application as granules is recommended, and thus the way of application should be optimized to control the solubility. In this study struvite slow release fertilizers were designed by dispersing St particles (25, 50, and 75 wt%) in a biodegradable and hydrophilic matrix of thermoplastic starch (TPS). It was shown that, in citric acid solution (pH= 2), TPS promoted a steadier P-release from St compared to the pure St pattern. In a pH neutral sand, P-difusion from St-TPS fertilizers was slower than from the positive control of triple superphosphate (TSP). Nevertheless, St-TPS featured comparable maize growth (i.e. plant height, leaf area, and biomass) and similar available P as TSP in sand after 42 days of cultivation. These results indicated that St-TPS slow P release could provide enough P for maize in sand,achieving a desirable agronomic efciency while also reducing P runof losses in highly permeable soils
