• Abstract: Fertilizer production in Brazil faces significant challenges, such as raw material scarcity and high dependence on mineral fertilizers, especially potash fertilizers, which are mostly imported from countries like Russia. The extensive use of these fertilizers depletes the soil, reducing its productivity and causing harmful effects like acidification and structural deterioration. Among essential macronutrients, phosphorus and potassium are non-renewable resources, with phosphorus being especially critical due to its geological limitation. In this context, organomineral fertilizers emerge as an alternative. By combining organic and mineral matter, they provide essential nutrients and improve soil structure, enhancing water retention and biological activity. Studies show that these fertilizers reduce costs, promote greater independence from external markets, and address environmental issues, such as the use of urban and rural waste. With slow-release properties, they prevent nutrient losses and are particularly beneficial for sandy soils. The aim of this study was to present a current overview of the advantages of using organomineral fertilizers, considering the Brazilian scenario that requires new fertilization technologies for crops.
