BACKGROUND This paper details the results of solubilization of phosphates in spent mushroom substrate ( SMS ). As a substrate for the process, bones as a source of phosphates and SMS as medium were used. RESULTS The process was conducted for 9 months and at the end of the process the substrate obtained was characterized as having a two times higher amount of available phosphorus (express as P 2 O 5 ), which was confirmed by FTIR and SEM‐EDX analysis. A decrease in pH was observed. Strong correlation was found between temperature and the effectiveness of the process ( P =0.000, r = 0.772). Solubilization combined with the degradation process lowered the C/N ratio from 13.6:1 to 11.7:1. The utilitarian properties of the substrate obtained were evaluated in germination tests. CONCLUSION The substrate obtained was characterized as having two times more available phosphorus and can serve as a biofertilizer for the cultivation of plants. © 2016 Society of Chemical Industry
