Abstract

The study was conducted to assess the fertility potential of cotton soils
in Côte d’Ivoire. A total of 500 plots of cotton farmers in 5 regions of the
cotton basin was selected for soil sampling in the horizon 0-20 cm. The
chemical analyzes of soil samples in the laboratory were performed on the
following parameters: particle size, pHwater, organic matter, total N, available
P, K, Ca, Mg and Cation Exchange Capacity (CEC) of soil. The physical
characterization revealed that the studied soils are mainly sandy texture in the
surface horizon. This gives them a very low retention capacity. The chemical
characterization of soils showed that they have reactions ranging from slightly
acid to neutral (6.4 <pH<7). These soils have very low levels of total organic
matter, total nitrogen, available phosphorus (in northern, south-central and
western regions), calcium, potassium, and low values of cation exchange
capacity.
