  ABSTRACT: The study of the reference state of the physico-chemical fertility of the soils of the pilot site of the National Institute of Pedology in the commune of Kelle Gueye to test the effect of phosphocomposte on cowpea and groundnut, allowed us to better understand the aptitudes of the above-mentioned crops. The methodology used consisted of taking soil samples on a regular 25 m grid, carrying out complete physico-chemical analyses at the INP laboratory and an analysis of climatic parameters. The results obtained were used to produce thematic maps to better interpret the various parameters. The physico-chemical analyses at the 0 - 20 cm horizon show a pH (6.1 - 7.9) close to neutral and a non-saline soil (EC
