To maintain this performance, it is necessary to continuously increase productivity. Therefore, the use of fertilizers that replenish the macronutrients nitrogen (N), phosphorus (P), and potassium (K) becomes indispensable to guarantee high yields and quality in agricultural production. The central problem addressed by this research is to understand how fertilization with NPK fertilizers can contribute to increased agricultural productivity in Brazil, while simultaneously promoting sustainable production. In this context, the importance of proper fertilization management is highlighted, considering factors such as soil type, crop, climatic conditions, and technical recommendations, in order to avoid waste and environmental degradation. The analysis of publications allows us to understand the main practices related to the use of NPK fertilizers, their agronomic benefits, as well as the challenges associated with the sustainability of agricultural production in the country. To this end, the study is based on a literature review with a qualitative and exploratory approach, using sources such as books, articles, and journals available in academic databases such as SciELO and Google Scholar. In general, the research shows that the proper use of NPK fertilizers is essential for strengthening Brazilian agriculture, as it allows for a combination of productivity and sustainability. Thus, it concludes that balanced and technically guided fertilization represents a fundamental strategy for the sustainable development of agriculture in Brazil.ptFertilizante NPKAdubação NPKProdutividade agrícolaFertilidade do solo.Trabalho de Conclusão de CursoCIENCIAS AGRARIAS::AGRONOMIA::CIENCIA DO SOLO::FERTILIDADE DO SOLO E ADUBACAO
