The work was conducted in the north of Cote d’Ivoire, central pivot cotton production savannah area, to make the diagnosis of soil fertility for cotton cropping. Cotton cropping, the mainstay of the savannah's economy, suffered from low productivity in relation to the soils chemical properties. Prior cultivation, soils samples were collected at a depth of 0 to 30 cm, collecting 32 simple samples to generate a complete sample. The samples were sent to the soil laboratory to measure the pH unities, CEC, nitrogen, phosphorus, potassium, calcium, magnesium, sodium, iron, zinc, copper and manganese contents. In order to facilitate the interpretation of analysis results, the nutrients critical level recommended for optimum production of cotton were used. Results showed that soils had pH ranging from 4.4 to 6.4. On the other hand, the need to add nitrogen, magnesium and phosphorus to the soils and to augment the low carbon, calcium and potassium content. There is the need to search for fertilizer formulations with nitrogen, magnesium phosphorus and calcium for the Cote d'Ivoire cotton belt.

En Côte d’Ivoire, la pauvreté des sols est une contrainte pour la productivité agricole. L’objectif de cette étude était de produire un compost à base de rafles de palmier afin d’améliorer les propriétés physicochimiques des sols pauvres en matières organiques. Quatre traitements T0 (720 kg de rafles + 0 kg de fientes de volaille), T1 (720 kg de rafles + 200 kg de fientes de volaille), T2 (720 kg de rafles + 400 kg de fientes de volaille) et T3 (720 kg de rafles + 600 kg de fientes de volaille), ont été compostés durant 6 mois. Les teneurs en nutriments et éléments traces métalliques (ETM) dans chacun des traitements ont été évaluées et comparées les unes par rapport aux autres. Le traitement T3 a révélé des teneurs élevées en N (14840 mg.kg-1), P (6327,5 mg.kg-1), K (19930 mg.kg-1), Mg (14160 mg.kg-1) et Ca (4140 mg.kg-1) et des concentrations en ETM en deçà des seuils de toxicité avec Pb : 88,5 mg.kg-1, Zn : 167,5 mg.kg-1et Cr : 58 mg.kg-1). Ce compost pourrait donc être utilisé comme amendement pour ces ferralsols marginaux dans le Sud-Ouest de la Côte d’Ivoire. © 2020 International Formulae Group. All rights reserved.

The aim of this study is to produce compost based on palm stalks to improve the physico-chemical properties of sandy soils with low organic matter content. Four treatments T0 (720 kg of empty fruit bunch + 0 kg of chicken manure), T1 (720 kg of empty fruit bunch + 200 kg of chicken manure), T2 (720 kg of empty fruit bunch + 400 kg of chicken manure) and T3 (720 kg of empty fruit bunch + 600 kg of chicken manure) of mixed various quantities of palm empty fruit bunch and chicken manure were up in field for 6 months. The levels of nutrients and heavy metal contents in each treatment were evaluated and compared against each other. Treatment T3 highlights high levels of N (14840 mg.kg-1), P (6327.5 mg.kg-1), K (19930 mg.kg-1), Mg (14160 mg.kg-1) and Ca (4140 mg.kg-1) and heavy metal content below the toxicity thresholds (Pb: 88.5 mg.kg-1, Zn: 167.5 mg.kg-1 and Cr: 58 mg.kg-1). This compost could therefore be used as sandy soil amendment in the South West of Côte d’Ivoire. © 2020 International Formulae Group. All rights reserved.

This study examined the distribution of Escherichia coli (E. coli) resistant to eleven antibiotics and possible relationships among physico-chemical parameters and these resistances. It was carried out over two years during four climatic seasons in five lakes of the Yamoussoukro lake system in Côte d'Ivoire. The physicochemical parameters of the lakes studied are temperature, pH, dissolved oxygen (DO), dissolved organic carbon (DOC), turbidity, nitrates, orthophosphates and ammoniacal nitrogen. A total of 744 water samples were collected from five (5) lakes belonging to the lake system, over a two-year period, during four dry and four wet seasons. Escherichia coli loadings were evaluated after isolation on specific chromogenic medium COMPASS ECC Agar and the susceptibility to antibiotics by the agar diffusion method. Physico-chemical parameters were evaluated according to international standards. The physico-chemical results showed that the nutrient contents evolved generally from upstream to downstream of the lake system, independently of the sources of pollution of five lakes of system. However, the lake B, in upstream of the lake system, showed levels of nitrate, orthophosphate and ammoniacal nitrogen often similar to the downstream lakes. This demonstrates a source of chemical pollution in this lake, which flows to lakes D and E, which are themselves subject to other pollution. Bacterial loads and bacterial resistance to antibiotics have strictly evolved from upstream to downstream of the system. Most isolates were resistant to ampicillin (16.46%), tetracycline (12.87%), ciprofloxacin (12.86%) and sulfamethoxazole (10.14%). Antibiotic resistance patterns of E. coli isolates were similar in both years studied, but higher during rainy seasons (GRS and SRS). The spearman rank correlations and the principal component analysis (PCA) revealed significant correlations between bacterial resistance to antibiotics in lakes and water physico-chemical parameters. Turbidity and DOC can help to determine the main resistances in the lake D. Orthophosphates can help to understand the resistance of chloramphenicol and the nitrates can help to understand the resistance of ampicillin in the lake B. Resistance in the lakes A, B and C can be influenced by dissolved oxygen. Overall, this study provided baseline information on bacterial resistance in the lakes of Yamoussoukro in Côte d'Ivoire, showing that these lakes could be reservoirs of antibiotic resistance, potentially dangerous to public health.
