Solubility of ground phosphate rock was increased resulting from co-composting with organic substances, which meant that bioavailability of phosphorus increased. All the tested composts were characterized by a higher ratio of ammonium citrate soluble phosphorus to total phosphorus than non-composted GPR.

Rock phosphate RP addition in cow-dung waste-paper mixtures at rates above 2 P has been reported to increase the rate of bio-transformation and humification of organic waste mixtures during vermicomposting to produce organic fertilizer for organic farming. However, the optimization of RP for vermicomposting was not established. The objective of this study was to determine the optimal.

The phosphate rock mining industry is concentrated in a few countries and is subject to geopolitical dynamics. The phosphate derived from the rock is a key ingredient in chemical fertilizers used in industrial agriculture. Therefore the industry claims that securing a reliable supply of phosphate rocks is essential to food security.
