In this study, the effect of phosphates flotation wastes (PFW) and phosphogypsum (PPG) on organic biomass degradation, compost quality, and plant growth was examined. Our results showed that PFW and PPG improve composting mechanisms, accelerate organic substance degradation, and increase fertilizing elements (P₂O₅, K₂O, MgO, CaO). The low level of C/N ratio in the finished composts reflects the good quality of the prepared composts. The effect of PFW and PPG additives on plant growth was evaluated using chickpea plants. Addition of PFW and PPG enhanced significantly chickpea plant growth and development, compared to the control, especially when added simultaneously. These results indicate that PFW and PPG can be utilized in compost formulations, and as fertilizers in agricultural practices to improve chickpea plant growth and development, while at the same time reducing the environmental and health risks associated with their disposal.

在这项研究中，研究了磷酸盐浮选废物（PFW）和磷石膏（PPG）对有机生物量降解，堆肥质量和植物生长的影响。我们的结果表明，PFW和PPG改善了堆肥机理，加速了有机物质的降解，并增加了施肥元素（P ₂ O ₅，K ₂O，MgO，CaO）。制成的堆肥中较低的C / N比值反映了制成的堆肥的良好质量。使用鹰嘴豆植物评估了PFW和PPG添加剂对植物生长的影响。与对照相比，PFW和PPG的添加显着增强了鹰嘴豆植物的生长发育，尤其是同时添加时。这些结果表明，PFW和PPG可以用于堆肥配方，并且可以用作农业实践中的肥料，以改善鹰嘴豆植物的生长和发育，同时减少与其处置相关的环境和健康风险。
