Abstract


The study of soil resources of Mayo-Danay, located in the tropical zone of Cameroon, shows a diversity of soils characterized by specific properties. Indeed, this study area is generally a plain landscape whose average relative altitude (300 m). However, it indicates a vegetation of savanna type, very dominant. Hydrologically, Logone River, Maga Lake and tributary streams of the Mandara Mountains regularly flood the study area. The sharing of these parameters leads to soil’s genesis, which have a sandy texture for floodplain soils and a very dominant clay texture for lacustrine soils. Otherwise, the geochemistry of these soils shows SiO2 contents globally 70% in the different soils studied; Al2O3 contents are less than 10% in lacustrine soils and less than 5% in floodplain soils; while the major elements data of soils such as Fe2O3, CaO and MgO indicate relatively low contents (≤2%) on soils studied. In addition, the mineralogy index of alteration expresses a moderate alteration of these soils. Thus, the distribution of these major elements of soil reveals its susceptibility to zonation, which is a consequence of intrinsic and extrinsic parameters to formation and differentiation of soils of the study area.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
