The state of Rio Grande do Sul, a critical node in Brazil's agricultural output, is executing a strategy to drastically cut its near-total reliance on imported nitrogen fertilizer by pivoting to domestic green hydrogen production. The move, centered on transforming renewable energy into green ammonia and urea—essential nitrogen inputs—signals Brazil's intention to improve farm-level economics and meet rising global demand for lower-carbon grain exports. Currently, the state imports about 90% of its nitrogen fertilizers, leaving its massive soybean and corn crops vulnerable to geopolitical shocks and the high cost of a U.S. dollar that today trades at R$5.1247.
