Application of soil amendments is a viable strategy to decrease soluble P in surface soils. Since soluble P is reduced through different mechanisms that are amendment\u2010specific, blended amendments could be a better approach than single amendment applications; however, very little information is available on blended amendment effects in reducing P loss from soils.

Treated soils were saturated and incubated for 2 weeks and analyzed for WEP (an indicator of risk of P loss) and Mehlich\u20103 P (plant\u2010available P) concentrations. All amendments significantly reduced the WEP concentrations compared to control in both soils. The blended amendments, particularly gypsum\u2013alum blends, performed better than unblended amendments in reducing the potential risk of P loss. Mehlich\u20103 P concentration was not influenced by amended treatments, suggesting no significant decrease in plant\u2010available P with amendments in both soils.\n                  <\/jats:p>","DOI":"10.1002\/jeq2.20673","type":"journal-article","created":{"date-parts":[[2025,1,14]],"date-time":"2025-01-14T03:11:12Z","timestamp":1736824272000},"page":"410-419","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Blended soil amendments: A viable strategy to reduce soluble phosphorus in soils"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7613-0667","authenticated-orcid":false,"given":"Darshani","family":"Kumaragamage","sequence":"first","affiliation":[{"name":"Department of Environmental Studies and Sciences The University of Winnipeg  Winnipeg Manitoba Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4711-5714","authenticated-orcid":false,"given":"Haven","family":"Soto","sequence":"additional","affiliation":[{"name":"Department of Environmental Studies and Sciences The University of Winnipeg  Winnipeg Manitoba Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Van","sequence":"additional","affiliation":[{"name":"Department of Environmental Studies and Sciences The University of Winnipeg  Winnipeg Manitoba Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4352-1813","authenticated-orcid":false,"given":"Douglas","family":"Goltz","sequence":"additional","affiliation":[{"name":"Department of Chemistry The University of Winnipeg  Winnipeg Manitoba Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7099-9110","authenticated-orcid":false,"given":"Inoka","family":"Amarakoon","sequence":"additional","affiliation":[{"name":"Department of Environmental Studies and Sciences The University of Winnipeg  Winnipeg Manitoba Canada"},{"name":"Department of Soil Science University of Manitoba  Winnipeg Manitoba Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,14]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11104\u2010005\u20105929\u20106"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2014.10.0457"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0925\u20108574(99)00026\u20109"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/jeq2.20319"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.est.2c01185"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1139\/cjss\u20102017\u20100076"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jglr.2018.04.001"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1071\/CP13435"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/07011784.2015.1131629"},{"key":"e_1_2_9_11_1","volume-title":"The Canadian system of soil classification","author":"Canadian Agricultural Services Coordinating Committee","year":"1998"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2000.00472425002900060027x"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/jeq2.20179"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11270\u2010023\u201006388\u20104"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1306\/74D729D2\u20102B21\u201011D7\u20108648000102C1865D"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2019.02.0091"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2018.08.0308"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.2136\/sssaj2011.0223"},{"key":"e_1_2_9_19_1","doi-asserted-by":"crossref","first-page":"383","DOI":"10.2136\/sssabookser5.1.2ed.c15","volume-title":"Methods of soil analysis","author":"Gee G.
