The researchers studied how using nano-synergism fertilizer on winter wheat affects its yield and quality. They found that using this fertilizer increased wheat yield by 12.34%-19.76%, decreased protein content by 7.52%, and increased fat content by 33%. Using low amount nano-synergism fertilizer saved 10 kg of fertilizer per 667 m2 compared to high amount urea fertilizer, while also saving labor by reducing the number of topdressing processes needed. This research provides a foundation for understanding how nanometer materials can improve fertilizer application.
