Food security is one of the biggest challenges for the next few decades, especially with the accelerated population growth rates. Therefore, achieving a better nutrient use efficiency is crucial to enhance crop yields and productivity, which depend directly on how macronutrients are supplied. It is notably complex because fertilizers are often applied as granules instead of more soluble powdered forms. Here, we propose a new model for an all-in-one NPK fertilizer production, which allows quickly adjustable compositions in multi-nutrient granules. Thus, thermoplastic starch has been used as a biodegradable matrix binder mixed with the fertilizers in a continuous process by extrusion. Urea and KCl were considered as N and K sources, respectively. P sources with different solubilities (triple superphosphate (TSP) and Bayovar and Patos phosphate rocks) have been tested and compared. The greenhouse experiment revealed that the TSP composite promoted superior biomass production than the standard application, in addition to an overall better nutrient uptake. While Bayovar did not benefit from the all-in-one granule, Patos results were improved in this system, revealing a boost in its solubilization.

为NPK多合一颗粒肥料量身定制高效材料
粮食安全是未来几十年最大的挑战之一，特别是随着人口增长率的加快。因此，提高养分利用效率对提高作物产量和生产力至关重要，而这直接取决于大量养分的供应方式。这很复杂，因为肥料通常以颗粒形式使用，而不是更易溶解的粉末形式。在这里，我们提出了一种新型的NPK复合肥料生产模型，该模型可以在多种营养颗粒中快速调节成分。因此，热塑性淀粉已被用作通过挤出连续过程中与肥料混合的可生物降解的基质粘合剂。尿素和氯化钾分别被视为氮和钾源。已测试并比较了具有不同溶解度的P源（三重过磷酸盐（TSP）以及Bayovar和Patos磷酸盐岩石）。温室试验表明，除了总体上更好的养分吸收外，TSP复合材料还促进了比标准应用更好的生物量生产。尽管Bayovar没有从多合一颗粒中受益，但Patos在该系统中的结果有所改善，显示出其增溶作用的增强。
