Abstract:
Purpose This paper investigates the composting recovery of different bio-wastes and the use of the composts produced as soil fertilizer and organic amendment.Method A composting process was carried out for ۱۱۱ days using different organic wastes (fruits, vegetables, olive pomace, poultry, and cattle manure). The physicochemical properties of the generated compost were determined. The quality of the compost produced was evaluated by measuring pH, carbon/nitrogen (C/N), dry matter, and organic matter. A phytotoxicity test (germination test) was conducted to complete the analysis.Results The results of the physicochemical properties complied with AFNOR standards. The pH ranged between ۷.۳ and ۸.۷. The C/N ratio was between ۱۰.۰۵ and ۱۸.۴۶, and organic matter content varied between ۳۳.۶ and ۷۲.۷%. The phytotoxicity test showed that the safety of compost as a soil amendment is related to the applied dose and the type of crop.Conclusion The physicochemical parameters and phytotoxicity test showed that the compost obtained can be used as organic fertilizer due to its organic matter content and mineral elements.
