Kamafugite is a group of ultrapotassic igneous minerals, composed of leucitite, olivine, leucite, kalsilite and melilite. Based on its composition, it would be an alternative source of potassium, phosphorus and other important nutrients in agriculture. This research analyzed the physical properties of the material and its potential as an alternative fertilizer. Samples of the Kamafugite powder in natura were enriched adding MAP, Elementary S, Ulexite, and the resulting powder was granulated (fertilizer). The materials were analyzed by SEM, EDS, TG/DTA, XRD, Raman spectroscopy and profilometer. Therefore, the results show the importance of Kamafugite grain to be used as a local and more affordable fertilizer, considering the lack of potassium and phosphorus resources in Brazil.
