- Abstract
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.
