001047015 520__ $$aIntensive fertilization has become necessary to supply nutrients for plant growth under current agricultural practices aimed at meeting global food demands. Macronutrients such as phosphorus and sulfur are essential for the plant growth cycle and, consequently, for improving productivity. Struvite (MgNH₄PO₄·6H₂O) is a valuable phosphorus source that can even be recycled from wastewater; however, it typically exhibits low solubility. Similarly, elemental sulfur (S⁰) offers a high-concentration source of sulfate, but its availability is constrained by the soil’s capacity to support microbial S⁰ oxidation [1]. In this study, we propose the integration of these nutrients into a composite material based on a biodegradable starch matrix. This matrix enables the encapsulation of acidifying agents, including Aspergillus niger, associated with the carbon cycle, and Acidithiobacillus thiooxidans, associated with the sulfur cycle—both of which are native soil microorganisms. This strategy effectively enhanced nutrient solubility, with the starch/S⁰/phosphorus biofertilizer composite showing promising results in soil incubation experiments. These findings contribute to the advancement of environmentally friendly fertilizers and support the development of more sustainable agricultural practices. Additionally, this approach may open new avenues for the use of low-solubility nutrient sources in future fertilizer formulations.
