Lower P solubility in litter is generally attributed to aluminum\u2010phosphate complex formation. However, recent studies suggest that alum additions to poultry litter may influence organic P mineralization. Therefore, alum\u2010treated and untreated litters were incubated for 93 d to assess organic P transformations during simulated storage. A 62\u2010d soil incubation was also conducted to determine the fate of incorporated litter organic P, which included alum\u2010treated litter, untreated litter, KH<jats:sub>2<\/jats:sub>PO<jats:sub>4<\/jats:sub> applied at 60 mg P kg<jats:sup>\u22121<\/jats:sup> of soil, and an unamended control. Liquid\u2010state <jats:sup>31<\/jats:sup>P nuclear magnetic resonance indicated that phytic acid was the only organic P compound present, accounting for 50 and 45% of the total P in untreated and alum\u2010treated litters, respectively, before incubation and declined to 9 and 37% after 93 d of storage\u2010simulating incubation. Sequential fractionation of litters showed that alum addition to litter transformed 30% of the organic P from the 1.0 mol L<jats:sup>\u22121<\/jats:sup> HCl to the 0.1 mol L<jats:sup>\u22121<\/jats:sup> NaOH extractable fraction and that both organic P fractions were more persistent in alum\u2010treated litter compared with untreated litter. The soil incubation revealed that 0.1 mol L<jats:sup>\u22121<\/jats:sup> NaOH\u2013extractable organic P was more recalcitrant after mixing than was the 1.0 mol L<jats:sup>\u22121<\/jats:sup> HCl\u2013extractable organic P. Thus, adding alum to litter inhibits organic P mineralization during storage and promotes the formation of alkaline extractable organic P that sustains lower P solubility in the soil environment.<\/jats:p>","DOI":"10.2134\/jeq2007.0239","type":"journal-article","created":{"date-parts":[[2008,2,11]],"date-time":"2008-02-11T21:40:21Z","timestamp":1202766021000},"page":"469-476","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["The Impact of Alum Addition on Organic P Transformations in Poultry Litter and Litter\u2010Amended Soil"],"prefix":"10.1002","volume":"37","author":[{"given":"Jason G.","family":"Warren","sequence":"first","affiliation":[{"name":"Animal Waste Management Research Unit USDA\u2010ARS 230 Bennett Lane Bowling Green KY 42104"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad J.","family":"Penn","sequence":"additional","affiliation":[{"name":"Dep. of Plant and Soil Sciences Oklahoma State Univ. 368 Agricultural Hall Stillwater OK 74078\u20106028"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua M.","family":"McGrath","sequence":"additional","affiliation":[{"name":"Dep. of Environmental Science and Technology Univ. of Maryland 0214 H.J.
