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. |
