In this study, a controlled-release inhibitor-enhanced nitrogen fertilizer (CYRF) was developed by integrating a polyurethane controlled-release membrane with a 3,4-dimethylpyrazole phosphate (DMPP) nitrification-inhibitor layer. Its structural characteristics, nutrient release behavior, and nitrogen-regulating performance were evaluated using scanning electron microscopy, energy-dispersive X-ray spectroscopy, static water incubation, soil incubation at different temperatures and field nitrogen-15 (\u00b9\u2075N) tracing. Morphological and elemental analyses confirmed that CYRF possessed a distinct multilayer structure consisting of an outer controlled-release membrane and an inner DMPP-containing inhibitor layer, providing a structural basis for the coordinated release of urea nitrogen and DMPP. Under static water incubation at 25 \u00b0C, the cumulative release of urea nitrogen increased from 0.40% at 7 d to 87.50% at 98 d, while DMPP release increased from 0.70% to 79.00% over the same period. DMPP was released slightly earlier than urea nitrogen during the 21\u201349 d incubation period, and their cumulative release rates were strongly positively correlated (r = 0.975, P &amp;lt; 0.001). Soil incubation showed that CYRF consistently enhanced ammonium nitrogen retention while suppressing nitrate nitrogen accumulation across different temperatures. Compared with the controlled-release fertilizer (CRF), CYRF increased ammonium nitrogen retention by 37.3% and reduced nitrate nitrogen accumulation by 16.4% at 15 \u00b0C. At 25 \u00b0C, CYRF reduced nitrate nitrogen accumulation by 97.0\u201398.7% during the 50\u201390 d incubation period, while at 35 \u00b0C it decreased nitrate nitrogen accumulation by 42.0%. Field \u00b9\u2075N tracing further showed that, compared with CRF(\n                    <jats:sup>15<\/jats:sup>\n                    N), CYRF(\n                    <jats:sup>15<\/jats:sup>\n                    N) significantly increased\n                    <jats:sup>15<\/jats:sup>\n                    N utilization rates by 14.60 and 5.30 percentage points and reduced nitrogen loss rates by 11.45 and 11.11 percentage points in winter wheat and summer maize, respectively. Overall, CYRF effectively synchronized controlled nitrogen release with nitrification inhibition, providing a promising strategy for improving nitrogen use efficiency and reducing nitrogen losses in agricultural production.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1901755","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T05:31:16Z","timestamp":1786339876000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Preparation, characterization, and performance evaluation of a controlled-release inhibitor-enhanced nitrogen fertilizer"],"prefix":"10.3389","volume":"17","author":[{"given":"Fengru","family":"Gao","sequence":"first","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]},{"name":"College of Agronomy, Heilongjiang Bayi Agricultural University","place":["Daqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhizhuang","family":"An","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingwei","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Life Science and Technology, Heilongjiang Bayi Agricultural University","place":["Daqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiwen","family":"Qiu","sequence":"additional","affiliation":[{"name":"New Zealand Institute for Bioeconomy Science Limited","place":["Hamilton, New Zealand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiyou","family":"Sun","sequence":"additional","affiliation":[{"name":"Institute of Agricultural Resources and Environment, Hebei Academy of Agriculture and Forestry Sciences","place":["Shijiazhuang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haize","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Agronomy, Heilongjiang Bayi Agricultural University","place":["Daqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yishan","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingxuan","family":"Pan","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]},{"name":"College of Life Science and Technology, Heilongjiang Bayi Agricultural University","place":["Daqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Dong","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]},{"name":"College of Agronomy, Heilongjiang Bayi Agricultural University","place":["Daqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangyang","family":"Xie","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]},{"name":"College of Life Science and Technology, Heilongjiang Bayi Agricultural University","place":["Daqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinling","family":"Lv","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Henan Academy of Agricultural Sciences","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Xiao","sequence":"additional","affiliation":[{"name":"Institute of Plant Nutrition, Resources and Environment, Beijing Academy of Agriculture and Forestry Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,10]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"36","DOI":"10.1016\/j.agee.2016.02.003","article-title":"Rainfall amount and distribution regulate DMPP effects on nitrous oxide emissions under semiarid Mediterranean conditions","volume":"238","author":"Abalos","year":"2017","journal-title":"Agric.
