Description:	TERRATIVA has several ultrapotassic igneous rocks projects in different regions of Brazil. In addition, the company is looking at areas with potential for soil conditioners such as the Acreúna project. The rocks of Acreúna project occur in large volumes and show mineral potential to be used directly or in blends with each other or syenites, as soil conditioner or K-fertilizer. Such rocks have significant K2O, CaO and MgO contents, important macronutrients, and low-crystallinity mineralogical assemblages which facilitates the release of macro- and micronutrients and causes a good residual effect for plants
