Abstract:
The aim of this research is to analyse the influence of mineral fertilization on the chemical characteristics of ferrallitic soil under conventional and organic pineapple cultivation in the municipalities of Allada, Tori-Bossito and Zè in South Benin. For this purpose, the chemical parameters (pHeau, pHKCl, C-organique, N-total, P-assimilable, and changeable basis) of pineapple-cultivated soils and pineapple-free fallow soils were determined. The two-factor analysis of variance (field types and communes) was performed using Statistical Analysis System version 9.2 software and the means were compared using the Student Newman-Keuls test at the 5% threshold. The results revealed that the carbon content is higher (P < 0.05) in the pineapple-cultivated ferrallitic soil in the municipality of Allada compared to the pineapple-free ferrallitic fallow soil. The water pH of ferrallitic soils under pineapple cultivation are acidic. The high values of potassium, C/N ratio and organic matter were recorded in the ferrallitic soils of the municipality of Tori-Bossito. Mineral fertilisation under pineapple cultivation influences the organic matter,water pH and phosphorus of the soil.
