Objective: To evaluate the spatial variability of some chemical properties of a Cambisol soil, in order to establish specific agronomic management zones for cocoa cultivation. Methodology: A sampling of 42 georeferenced points equidistant at 40 m was carried out. Geostatistical variability maps were made with the results of the chemical analysis of the soil properties, using the ordinary Kriging interpolation technique. Results: It was found that the percentage of saturation of acidity (PSA), acidity and H+ showed high variability; P-Olsen and interchangeable K, Ca and Mg displayed medium variability, and pH, MO, CIC and Al presented low variability. Soil properties pH, PSA; Exchangeable P-Olsen, Ca and Mg showed high spatial dependence (25%) and OM, exchangeable K and CIC moderate spatial dependence (25-75%). Study limitations/Implications: The generated maps allowed the identification of partial areas with different variability, as well as the direction of greatest variability of the property as a function of distance. Conclusions: With the maps, it was possible to make recommendations for agronomic management depending on each specific management area.
