The present study aims to determine the optimal dose of ox dung and sowing density that optimize yield seed cotton in region BERE North-West Côte d'Ivoire. Six fertilizer doses (T0, T1, T2, T3, T4 T5) were tested. Among these six doses, T3 are composed a mixture NPK mineral fertilizer, T0 is T5 only cattle dung. These tested on plants through 4 seeding densities : low (LowD 50 cm x 80 with 2 pl...

Novel organo-Eu(III) luminophores, Eu(hfa)x(CPO)y and Eu(hfa)x(TCPO)y (hfa: hexafluoroacetylacetonate, CPO: 4-carboxyphenyl diphenyl phosphine oxide, TCPO: 4,4',4″-tricarboxyphenyl phosphine oxide), were synthesized by the complexation of Eu(III) ions with hfa moieties and CPO or TCPO ligands. The thermal and luminescent stabilities of the luminophores are extremely high. The decomposition temp...

The sorption affinity of iodide on organo-bentonite, modified with hexadecyl pyridinium (HDPy), was investigated the iodine–starch method coupled UV/Vis absorption spectroscopy. complex optimized in terms reaction time and sample compositions, based absorbance. batch experiment for organo-bentonites, using two different loading amounts HDPy, conducted to analyze influence equilibrium time, liqu...

Soil quality is one of the main factors that affect growth and tea (Camellia sinensis L.) plantations. The formation organo-mineral complex critical influence evolution soil fertility. This study used chemical analyses spectroscopy to effects inorganic organic fertilizer on nutrients in garden soil. SR-FTIR analysis revealed clay minerals were connected as nuclei with capacity bind carbon, this...
