The high price of chemical inputs has led producers to use other sources of fertilizer such as chicken manure. However, the direct and compost-free application of these wastes as practiced by producers is a potential source of soil acidification and environmental contamination that cannot adequately restore soil fertility. The objective of the study was to evaluate the effects of composting times on the chemical fertility of the composts produced. The study was carried out at the Jean Lorougnon Guédé University in the Tazibouo district of Daloa, in the centre-west of Côte d'Ivoire. Twelve (12) piles of chicken manure were made up of 3 piles per treatment corresponding to the different composting times (T14, T21, T28, T35 days). Four treatments rated T14, T21, T28 and T35 corresponding to 14, 21, 28 and 35 days of composting of the feces were compared to a control treatment T0 (composted chicken feces). The study found that composting chicken manure has positive effects on its chemical fertility by improving the levels of most of the physical and chemical parameters of the composts produced. As a result, composting has reduced concentrations of trace metal elements, such as iron and zinc, in composted chicken droppings, which at high soil levels become toxic to plants. Composting the manure for 14 days by improving the fertility of the composts produced can therefore be recommended to growers for a better chemical quality of the compost produced.

Abstract
The high price of chemical inputs has led producers to use other sources of fertilizer such as chicken manure. However, the direct and compost-free application of these wastes as practiced by producers is a potential source of soil acidification and environmental contamination that cannot adequately restore soil fertility. The objective of the study was to evaluate the effects of composting times on the chemical fertility of the composts produced. The study was carried out at the Jean Lorougnon Guédé University in the Tazibouo district of Daloa, in the centre-west of Côte d'Ivoire. Twelve (12) piles of chicken manure were made up of 3 piles per treatment corresponding to the different composting times (T14, T21, T28, T35 days). Four treatments rated T14, T21, T28 and T35 corresponding to 14, 21, 28 and 35 days of composting of the feces were compared to a control treatment T0 (composted chicken feces). The study found that composting chicken manure has positive effects on its chemical fertility by improving the levels of most of the physical and chemical parameters of the composts produced. As a result, composting has reduced concentrations of trace metal elements, such as iron and zinc, in composted chicken droppings, which at high soil levels become toxic to plants.

Abstract: (french)
Le prix élevé des intrants chimiques ont amené les producteurs à utiliser d’autres sources de fertilisants telle que la fiente de poulets. Cependant, l’application directe et sans compostage de ces déchets telle que pratiquée par les producteurs constitue des sources potentielles d’acidification des sols et de contamination de l’environnement qui ne permettent pas de restaurer de manière suffisante la fertilité des sols. L’objectif de l’étude a été d’évaluer les effets des durées de compostage de la fiente sur la fertilité chimique des composts produits. L’étude a été réalisée au sein de l’Université Jean Lorougnon Guédé au quartier Tazibouo à Daloa, au Centre-Ouest de la Côte d'Ivoire. Douze (12) tas de fiente de poulet ont été constitués à raison de 3 tas par traitement correspondant aux différentes durées de compostage (T14, T21, T28, T35 jours). Quatre traitements notés T14, T21, T28 et T35 correspondant respectivement à des durées de 14, 21, 28 et 35 jours de compostage de la fiente ont été comparés à un traitement témoin T0 (fiente de poulet non compostée). L’étude a révélé que le compostage de la fiente de poulet induit des effets positifs sur sa fertilité chimique en améliorant les teneurs de la plupart des paramètres physiques et chimiques des composts produits. Aussi, le compostage a t-il permit de réduire dans les fientes de poulet compostées les concentrations des éléments traces métalliques, tels le fer et le zinc, qui à des fortes teneurs dans les sols deviennent toxiques pour les plantes. Le compostage de la fiente pendant 14 jours en améliorant la fertilité des composts produits peut donc être recommandé aux producteurs pour une meilleure qualité chimique du compost produit.
