Abstract

A soil survey was carried out on a B29 agricultural plot in Mamlanso, located in the Aboisso Comoé region (south-east of Côte d'Ivoire) in the period from November to January. The objective of this study is to evaluate the chemical potential of the Mamlanso B29 agropastoral farm study plot. The approach consisted in the opening of a track in the N290 ° direction along which rock and soil samples are taken from soil pits. The results of the chemical and physical analyzes associated with landscape observations revealed browned soils (Cambisols) derived from the sandy-dominated volcano-sedimentary complex formations, which are low in exchangeable bases (Al3 +, Fe2 + Fe3 +, Mn2 + and Na +), strongly desaturated, very weak cation exchange capacity. They have a good rate of mineralization and low organic matter content. In addition, the skin is acidic and their content of major elements (N, P and K) is not able to increase crop yield. The description of the soils highlights clay-silty-sandy textures with a high clay content. On the other hand, the laboratory analysis shows sandy soils with a low clay content on the same site. The chemical properties have a great influence on the quality of the soils, but the predominantly polyhedric structure from H2 and
lumpy at the level of H1 and the coarse texture, seems to be the character that conditions the drainage and the work of these soils. In view of these results, it would be interesting to enhance the organic matter content of B29 soils by the practice of organic
amendment. This would help improve its physical properties and mobilize certain chemical elements needed for agricultural production.
