| description | The common agricultural practice in the humid tropical forest zone of Cameroon is shifting cultivation,
which leads to a landscape mosaic system characterized by a diversity of land cover types. Our objective
was to evaluate soil properties and soil quality under these land cover types and to investigate on their
interrelationships. Topsoil samples (0–20 cm) were collected at the same time from 8 different land cover
types (bare soil with burned vegetation biomass (FR1), bare soil with unburned vegetation biomass (FR),
Chromolaena odorata fallow (JC), bush ligneous fallow (JR), secondary forest (SF), primary forest (FC),
Gilbertiodendron dewevrei forest (FG), and raffia and Uapacca forest (RA)) and analysed for routine
laboratory determinations. A soil quality index (SQI) computed based on soil chemical properties,
analysis of variance and multiple comparison tests were used to compare soils from different land cover
types. Principal component analysis (PCA) was used to select the most appropriate indicators that control
soil quality. Several soil properties showed high to very high coefficient of variation within the land cover
types. Organic matter was significantly high under forested land cover types (FC, FG, RA) and under bare
soil with burned vegetation (FR1). Soil quality differs significantly (p = 0.000) from one land cover to
another and shows the following ranking: SQI_FR1
SQI_FG > SQI_RA > SQI_FR > SQI_FC > SQI_JC >
SQI_FS > SQI_JR. Organic matter (OM), available P, calcium (Ca), and pHw combined, accounted for
88.5% of the variation of soil quality. The soil quality appeared to be highly influenced by ashes from
burned vegetation biomass which temporally enriches soils with nutrient elements and by the organic
matter supplied by forested land cover types.
