Description
Summary: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 (P 2 O 5 , K 2 O, 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.
