• Abstract: The growing demand for sustainable agricultural practices has driven the development of technologies that reconcile productivity with environmental responsibility. In this context, organomineral fertilizers have emerged as a strategic alternative to conventional fertilization by promoting the reuse of organic waste and diversifying nutrient sources. This article presents a systematic review of the scientific literature on the use of organomineral fertilizers in Brazilian agriculture, focusing on their composition, application, agronomic efficiency, and environmental implications. Studies published between 2005 and early 2025 were analyzed, with an emphasis on experiments conducted on economically important crops such as maize, soybean, common bean, and lettuce. The results highlight significant agronomic benefits, including increased productivity, improved soil health, and reduced nutrient leaching. The most commonly used organic residues were cattle manure, poultry litter, and filter cake, predominantly applied to Oxisols. However, gaps remain regarding effectiveness in diversified systems and the standardization of these products. It is concluded that organomineral fertilizers are promising tools for Brazil’s agroecological transition, especially when aligned with public policies, technological advancements, and environmental regulations. Their use contributes to impact mitigation, strengthens the circular economy, and supports the achievement of sustainability goals in the agricultural sector.
