Change in a ferralsol physico-chemical properties under pineapple cropping system in southern of Benin

Abstract

Objectives:The study examines the evolution of soil properties under the main pineapple cropping system, in order to evaluate the effectiveness of this system towards maintaining sustainable productivity. Methodology and Results: The plots of different cropping durations (1.5, 3, 6, 7, 10, 15 and 16 years) were selected from the predominant pineapple cropping system. A fallow plot was identified in a neighbourhood of each selected pineapple plot. Soil profiles were installed in the selected fields and their adjacent fallows to characterize morphological and physico-chemical soil dynamics. The results showed that the values of the morphological and physical characteristics of the soil began to decrease after 10 years of pineapple cropping. The values of chemical characteristics started to decline after 7 years of pineapple cropping. Conclusions and application of findings:The main pineapple cropping system in the study region improves and maintains the morphological and physical characteristics of the soil up to 10 years of cultivation after which lower values were recorded. In general, the values of the chemical characteristics begin to decline after 7 years of pineapple cropping. It is important to study crop residue management practices that will better manager soil fertility and conservation. For a sustainable use of ferrallitic soils under pineapple, the fertilization system on the plateau of Allada should be strengthened by the addition of organic fertilizers with appropriate crop rotation. This will keep these lateritic soils under pineapple production over a longer period.

“…This also reflects the failure of their production techniques to maintain productivity, despite the use of mineral fertilizers. However, Sossa et al (2015) showed that these cropping systems affect the physical quality of the soil after 10 years and the chemical quality after 7 years of continuous use. For this shifting cultivation system, the abandonment of cultivated fields is not only due to soil fertility decline, but pathogens also harbored in the soil (Rohrbach and Johnson, 2003).…”

“…In this area, average annual rainfall is 1200 mm. The dominant soil type is a low-desaturated lateritic soil, commonly called "terre de barre" [22]. The soil physico-chemical analysis indicates that this is a soil of silty-clay-sandy texture, well drained, with an average pH of 5.6 and a C/N ratio of 11.2.…”

Détermination des doses optimales d’azote, de phosphore et de potassium pour la production de l’ananas (<i>Ananas comosus</i> (L.) Merrill, variété pain de sucre) au Sud du Bénin : comparaison de quatre modèles quadratiques

“…Malgré tous ses atouts, la production de l'ananas est limitée par la dégradation rapide de la fertilité des sols (Sossa et al, 2015 ;Atchada et al, 2021) ; ceci pourrait s'expliquer par une diversité des pratiques culturales (Agbangba et al, 2008 ;Agbangba et al, 2010). En effet, Sossa et al (2014) ont identifié cinq différents systèmes de culture d'ananas au Bénin qui se distinguent entre autres par les quantités d'engrais minéraux utilisées.…”
