| Abstract | Nitrate-based and ammonium-based fertilizers are widely used in agriculture, with global nitrogen fertilizer consumption reaching 108 million metric tons in 2022. Wheat, a major global crop, accounts for 18% of total fertilizer use, yet its nitrogen use efficiency is low, leading to significant nitrogen losses. These losses, occurring through ammonia volatilization, nitrate leaching, and nitrous oxide emissions, contribute to climate change, eutrophication, and soil degradation. Stabilized ammonium fertilizers have shown promise in reducing nitrogen losses and greenhouse gas emissions by keeping nitrogen in a stable ammonium form. This study was conducted over three years to assess the effectiveness of stabilized ammonium fertilization (AS) in wheat production, evaluating yield, nitrate losses, and fungal community shifts under selected nitrate and ammonium-based fertilization strategies. Stabilized ammonium fertilization combined with wheat varieties showed varying yield patterns according to the climate, with the most stable grain production in an intermediate climate year. Regardless of climate, this fertilization strategy reduced soil nitrate losses while maintaining ammonium availability and appeared to significantly increase the diversity and abundance of root-associated fungi during wheat flowering in the intermediate climate year. This study integrated agronomic performance and environmental impact assessments of AS fertilization on bread wheat, demonstrating its potential for sustainable integration into wheat production systems. |
