Stabilization of OM occurred more rapidly in mixtures with slaughter-house wastes, it was progressive in mixture with household refuses while tree leaves compost remained unstable. Carbon mineralization from compost samples was positively correlated to water soluble and hemicellulose-like organic fractions. Mixtures containing large proportions of household refuses reached the highest stability and total N but available N remained weak. Slaughter-house wastes in the initial mixtures made possible to reach good OM stabilization and the largest N availability. The nature of initial mixing influenced composting parameters, OM stabilization and N availability. it is suggested mixing household refuses and slaughter-house wastes with tree leaves to reach better amending and fertilizer qualities of composts. specialized Solid urban wastes Composting Stabilization Inorganic nitrogen Sub-Saharan Africa 068 076 101 3 1002-1013 2010 0960-8524 https://www.documentation.ird.fr/hor/fdi:010048390 10.1016/j.biortech.2009.08.101 0960-8524 [F B010048390] https://www.documentation.ird.fr/hor/fdi:010048390 https://www.documentation.ird.fr/intranet/publi/2009/12/010048390.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-12-21 2017-08-23 fdi:010048390 fre
