The present report addresses a novel theme regarding the mapping of potassium (K) in the Jacaraú-PB region. For this purpose, cartography and geoprocessing techniques were employed, as they play a crucial role in agronomy, contributing to enhancing agricultural production and natural resource management. For data management, Microsoft Excel was utilized to analyze, organize, and calculate the data, and the Quantum Geographic Information System (QGIS) was used to import, visualize, and analyze soil data, assisting in the mapping of exchangeable potassium (K). The results of the exchangeable K mapping displayed values ranging from low to very high. Low values were observed in the Tabuleiros region, while moderate to high values were found in the Depressão Sublitorânea region, where the soils derive from crystalline rocks in a semi-arid environment.
