Amidst global climate change, soil greenhouse gas (GHG) emissions have become a critical research focus. Agricultural soils, influenced by human activities and extensive fertilizer applications, have emerged as significant emission sources. However, fertilizer application also plays a vital role in enhancing crop yields and economic returns. Therefore, identifying a fertilizer that is both environmentally sustainable and capable of improving crop productivity has become a pressing need. The C ammonium sulphate (CCT-AS) is a newly developed, high-value, carbon (C)-based, enhanced-efficiency fertilizer using the CCT™ technology. This study was conducted in the Breton Plots region, examining a novel fertilizer and comparing its effectiveness against conventional fertilizers. Findings reveal that, relative to conventional fertilizers, this novel fertilizer increased crop stem biomass by 1014.52 kg/ha and yield by 1111.24 kg/ha. After applying CCT-As, Wheat's efficiency in utilizing nitrogen in the soil increased by 18%. The fertilizer achieves these gains primarily through enhancing nitrogen uptake, thereby promoting biomass accumulation and yield. Furthermore, its application increases elemental absorption in grains and plants. Additionally, the study found that the novel fertilizer exhibits synergistic effects when applied in combination with biochar, which has a low carbon content. Compared with the high C content of fertilizer with biochar, the yield increased by 28.57%. This research not only elucidates the efficacy and practicality of the new fertilizer but also provides valuable insights for sustainable agricultural practices and improved farmland soil management.
