However, under the background of phosphorus (P) risk management, the mechanism by which amino acid-enhanced phosphate fertilizers affect the transformation characteristics of soil P remains unclear. This study aimed to explore the effects of amino acid addition on soil P pools, crop yield, and phosphate fertilizer utilization through a soil column experiment. Five treatments were set up: (1) no fertilizer control (CK), (2) no phosphate fertilizer control (NK), (3) application of diammonium phosphate (P), (4) application of 0.5% amino acid-enriched diammonium phosphate (AP0.5), and (5) application of 5% amino acid-enriched diammonium phosphate (AP5), with six replicates for each treatment. The results showed that amino acid-enriched phosphate fertilizers promoted the absorption and utilization of P by wheat, and improved the yield and PUE, with the most significant effect in the AP0.5 treatment. Compared with the P treatment, the soil Olsen-P and Labile-P in the AP0.5 and AP5 treatments increased by 29.76% - 33.45% and 4.49% - 5.11%, respectively, with significant differences. However, there were no significant differences in the above indicators among treatments with different amino acid addition amounts. Path analysis between different P fractions and Olsen-P showed that H\n                    <jats:sub>2<\/jats:sub>\n                    O-P, NaHCO\n                    <jats:sub>3<\/jats:sub>\n                    -P\n                    <jats:sub>i<\/jats:sub>\n                    and NaOH-P\n                    <jats:sub>i<\/jats:sub>\n                    had the greatest direct effects on Olsen-P; while NaHCO\n                    <jats:sub>3<\/jats:sub>\n                    -Po and NaOH-Po may contribute indirectly to Olsen-P through their mineralization to NaHCO\n                    <jats:sub>3<\/jats:sub>\n                    -P\n                    <jats:sub>i<\/jats:sub>\n                    and NaOH-P\n                    <jats:sub>i<\/jats:sub>\n                    , respectively. The research results indicated that amino acid-enriched phosphate fertilizers can not only increase the yield but also do not increase the risk of P leaching, and have good environmental benefits compared with ordinary phosphate fertilizers. The addition of amino acids will promote the transformation of soil organic P to inorganic P to maintain the soil Olsen-P level. This study deepens the understanding of the effects of amino acid-enriched phosphate fertilizers on soil P pool characteristics, thus providing a basis for the development of new phosphate fertilizers.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1910255","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T05:33:37Z","timestamp":1785994417000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Amino acid enhanced phosphorus fertilizers enhance wheat yield and efficiency by optimizing soil phosphorus pools in wheat fields for soil phosphorus risk management"],"prefix":"10.3389","volume":"17","author":[{"given":"Lin","family":"Cheng","sequence":"first","affiliation":[{"name":"Department of Hydraulic Engineering, Wanjiang University of Technology","place":["Maanshan, Anhui, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linchuan","family":"Zhan","sequence":"additional","affiliation":[{"name":"Anhui Provincial Key Laboratory of Nutrient Cycling and Arable Land Conservation, Soil and Fertilizer Institute, Anhui Academy of Agricultural Sciences","place":["Hefei, Anhui, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zongya","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Hydraulic Engineering, Wanjiang University of Technology","place":["Maanshan, Anhui, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ximei","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Hydraulic Engineering, Wanjiang University of Technology","place":["Maanshan, Anhui, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tingting","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Hydraulic Engineering, Wanjiang University of Technology","place":["Maanshan, Anhui, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Hydraulic Engineering, Wanjiang University of Technology","place":["Maanshan, Anhui, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/j.geoderma.2022.115992","article-title":"Long-term (nearly a century) effects of fertilizer, lime and rice straw compost application on active aluminum and iron and available phosphorus in paddy fields","volume":"424","author":"Ando","year":"2022","journal-title":"Geoderma"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecolind.2022.109432","article-title":"Response of soil phosphorus fractions to land use change in the subalpine ecosystems of southeast margin of Qinghai-Tibet plateau, southwest China","volume":"144","author":"Azene","year":"2022","journal-title":"Ecol.
