Abstract Common organic composite fertilizers lack several bio-chemical and physical traits desirable in other fertilizers. This study aimed at investigating the role of Bomet red rock, BRR powder in improving green composite fertilizers from Tithonia diversifolia leaves and Musa acuminata stalks. The composite fertilizer without BRR powder was prepared by mixing the crude extracts of the two plants before addition of BRR powder (10% wt.) The composite fertilizer with and without the powder were analyzed for physical–chemicals, functional groups, surface, morphology, particle size, crystallinity and chemical composition. BRR powder was proven to boost the fertilizers pH, conductivity and solubility in water while reducing its loss on ignition value. Carboxylic and amide groups were sequestered while imprinting silica and ferric groups onto the fertilizer surface. BRR agglomerated the composite fertilizer particles, in the process smoothening the edges while reducing the particle sizes. The structure of the fertilizers changed from monoclinic to hexagonal with the dominant potassium alumino-silicate phase being replaced by silica upon addition of BRR. BRR powder was therefore found to positively affect the green composite fertilizer and should thus be used in preparation of quality and durable green compound fertilizers.

摘要 常见的有机复合肥缺乏其他肥料所具有的多种生化和物理特性。本研究旨在研究 Bomet 红岩、BRR 粉在改良 Tithonia diversifolia 叶和 Musa acuminata 茎绿色复合肥中的作用。不含 BRR 粉末的复合肥料是通过在添加 BRR 粉末（10% wt.）之前混合两种植物的粗提物制备的。分析了含有和不含 BRR 粉末的复合肥料的理化、官能团、表面、形态、粒度、结晶度和化学成分。事实证明，BRR 粉末可提高肥料的 pH 值、电导率和水中溶解度，同时降低其烧失值。羧基和酰胺基团被隔离，同时将二氧化硅和三价铁基团压印到肥料表面。BRR 将复合肥颗粒团聚，在此过程中使边缘平滑，同时减小颗粒尺寸。肥料的结构从单斜变为六边形，在添加 BRR 后，主要的铝硅酸钾相被二氧化硅取代。因此发现 BRR 粉对绿色复合肥产生积极影响，因此应用于制备优质耐用的绿色复合肥。肥料的结构从单斜变为六边形，在添加 BRR 后，主要的铝硅酸钾相被二氧化硅取代。因此发现 BRR 粉对绿色复合肥产生积极影响，因此应用于制备优质耐用的绿色复合肥。肥料的结构从单斜变为六边形，在添加 BRR 后，主要的铝硅酸钾相被二氧化硅取代。因此发现 BRR 粉对绿色复合肥产生积极影响，因此应用于制备优质耐用的绿色复合肥。
