摘　　要：Applying organic waste and inorganic additives during composting can be an effective and easy-to-control strategy for optimizing humification,maturation,and the availability of essential mineral elements in compost.In this respect,this study aims to evaluate the effect of organic(olive-mill waste and horse manure)and inorganic(phosphogypsum)additives on the evolution of maturity indices,aromatic compounds,and nutrient availability during composting.Four mixtures[horse manure+green waste(M1),olive-mill+green waste(M2),sewage-sludge+phos-phogypsum+green waste(M3),and green waste(M4)]were carried out.Physicochemical(temperature,pH,phosphorus,nitrogen,and carbon-to-nitrogen(C/N)ratio),infrared-spectroscopic,and phytotoxicity were monitored.The results showed that(in)organic additives have a positive effect on maturity and humification indices,pH stability,and the phosphorus and nitrogen availability in the composts produced.The horse manure additive reduced the carbon and increased the nitrogen,reducing the C/N ratio.Phosphogypsum and olive-mill reduced phytotoxicity,boosting the nitrogen and phosphorus availability of in composts.Fourier transform infrared spectroscopy(FT-IR)analysis revealed that phosphogypsum and olive-mill addition improved the aromatic compounds and reduced the aliphatic ones in M3 and M4 com-posts.These results suggest new approaches to promoting maturity and stability,as well as phosphorus and nitrogen availability in composts,through better use of organic waste and inorganic additives in composting.
