The ERP evaluated the single-laboratory validation results and recommended the method for First Action Official Method status and provided recommendations for achieving Final Action. Validation materials ranging from 4.4 to 52.4% P2O5 (1.7\u201322.7% P) and 3\u201362% K2O (2.5\u201351.1% K) were used for the validation. Recoveries from validation materials for citrate-soluble P and K ranged from 99.3 to 124.9% P and from 98.4 to 100.7% K. Recoveries from validation materials for acid-soluble \u201ctotal\u201d P and K ranged from 95.53 to 99.40% P and from 98.36 to 107.28% K. Values of r for citrate-soluble P and K, expressed as RSD, ranged from 0.28 to 1.30% for P and from 0.41 to 1.52% for K. Values of r for total P and K, expressed as RSD, ranged from 0.71 to 1.13% for P and from 0.39 to 1.18% for K. Based on the validation data, the ERP recommended the method (with alternatives for the citrate-soluble and the acid-soluble extractions) for First Action Official Method status and provided recommendations for achieving Final Action status.<\/jats:p>","DOI":"10.5740\/jaoacint.16-0050","type":"journal-article","created":{"date-parts":[[2016,6,15]],"date-time":"2016-06-15T15:17:09Z","timestamp":1466003829000},"page":"914-922","source":"Crossref","is-referenced-by-count":6,"title":["Determination of Phosphorus and Potassium in Commercial Inorganic Fertilizers by Inductively Coupled Plasma\u2013Optical Emission Spectrometry: Single-Laboratory Validation, First Action 2015.18"],"prefix":"10.1093","volume":"99","author":[{"given":"Nancy J","family":"Thiex","sequence":"first","affiliation":[{"name":"Thiex Laboratory Solutions, 46747 214th St, Brookings, SD 57006"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,11,27]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/99\/4\/914\/32426279\/jaoac0914.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/99\/4\/914\/32426279\/jaoac0914.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:15:15Z","timestamp":1584641715000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/99\/4\/914-922\/5658013"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,7,1]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,11,27]]},"published-print":{"date-parts":[[2016,7,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.16-0050","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2016,7,1]]},"published":{"date-parts":[[2016,7,1]]}}}
