Evaluation statistique et spatiale de la fertilité rizicole des sols hydromorphes (gleysols) de la région du Bélier (C te d'Ivoire)

Statistical and Spatial Evaluation of the Belier Region (Ivory Coast) Hydromorphic Soils Fertility for Paddy Field Cultivation. In the region of Belier localized in the centre of Ivory Caost, the agricultural production can be increased and diversified thanks to hydromorphic soils, but these soils are deserted most of the times by farmers. So, it appears very important to evaluate the fertility of these soils, in particular their fertility for paddy field cultivation. The method we adopted is based on parametric method of soils evaluation using GIS. The results show that 40%, 50% and 10% of the whole studied soils which covers 474,06 km2, are, respectively, not favourable, little favourable and very favourable for paddy field cultivation.
