中国華北平原の冬小麦試験で、フミン酸尿素（HAU）が従来尿素より収量を7.0〜23.3%、農家利益を8.8〜29.8%高めることを示した。HAU製造時のGHGは増えるが、圃場でのガス状窒素損失削減によりライフサイクル全体でGHGを1.9〜14.4%低減。180kgN/haのHAUは225kgN/haの従来尿素と同等の収量・利益を保ちつつ排出を14.4%削減した。
English
A winter wheat trial in the North China Plain shows humic acid urea (HAU) raised grain yield by 7.0–23.3% and farmer profits by 8.8–29.8% versus conventional urea. Though HAU production emits slightly more GHG, field N-loss reduction cuts whole-lifecycle emissions by 1.9–14.4%. HAU at 180 kg N/ha matched conventional urea at 225 kg N/ha while cutting emissions 14.4%.

📄 Abstract（原文）
Enhancing crop yield and reducing active nitrogen (N) loss are crucial for the efficient utilization of N fertilizer and the decrease of agricultural greenhouse gas (GHG) emissions. Humic acid urea (HAU), an efficient N fertilizer produced via in-situ incorporating small amounts of humic acid into urea production, has reached to 1 Tg of physical quantity of annual production in China for its efficiency enhanced via the comprehensive regulation on fertilizer-crop-soil systems. Therefore, we hypothesized that HAU would increase yield and reduce the carbon footprint relative to CU, and tested it in a winter wheat experiment at two N rates (225 and 180 kg ha⁻ 1 ) in the North China Plain. The results showed that the application of HAU resulted in a significantly higher grain yield by 7.0–23.3% than CU, and thus significantly increased farmer’s profits by 8.8–29.8%. HAU production resulted in more GHG emission than CU production by 6.9 kg CO 2 -eq Mg −1 ; however, the GHG emission from the field was significantly reduced (10.1–23.3%) by reducing gaseous N loss. In the whole life cycle, HAU resulted in lower GHG emissions (1.9–14.4%) in the winter wheat agroecosystem. HAU application also contributed to higher C fixation and ecosystem economic benefit. HAU at 180 kg ha −1 achieved a comparable yield and farmer’s profit with CU at 225 kg N ha −1 , while reduced GHG emission by 14.4%. Applicating HAU is an advantageous N management strategy for maintaining wheat yield with the lowest C footprint.
