A modified Hedley fractionation procedure was used to assess P forms in these sludge\u2010borne materials and in a biosolids compost (BSC) prepared from the same FBS. Each biosolids material exhibited a unique pattern of P distribution among fractions. The most available P forms, namely: (i) water\u2010soluble P (WSP); (ii) membrane\u2010P; and (iii) NaHCO<jats:sub>3<\/jats:sub>\u2013P, were stabilized by small rates of each of the chemicals; but the P transformation into more stable forms depended on the type of chemical added. The stabilized P forms were enhanced by high rates of CaO and FeSul, but were reduced by high rates of alum. The organic P (P<jats:sub>o<\/jats:sub>) in the first three fractions of the FeSul\u2010 and alum\u2010stabilized biosolids was enhanced by the chemical addition, and P<jats:sub>o<\/jats:sub> transformation from NaOH\u2010P<jats:sub>o<\/jats:sub> into NaHCO<jats:sub>3<\/jats:sub>\u2013P<jats:sub>o<\/jats:sub> was found in calcium\u2010stabilized biosolids. A positive relationship was found between NaHCO<jats:sub>3<\/jats:sub>\u2013P<jats:sub>o<\/jats:sub> and the NaHCO<jats:sub>3<\/jats:sub>\u2013extracted organic C in all chemically stabilized biosolids. One\u2010step extraction by NaHCO<jats:sub>3<\/jats:sub> or NaOH underestimated P extraction compared to the stepwise extraction. The reported results are consistent with solid\u2010state P speciation reported earlier and contribute important information for optimizing biosolids stabilization to reduce P loss after incorporation in soils and for maximizing soil capacity to safely store pre\u2010stabilized biosolids.<\/jats:p>","DOI":"10.2134\/jeq2007.0220","type":"journal-article","created":{"date-parts":[[2008,8,8]],"date-time":"2008-08-08T21:25:01Z","timestamp":1218230701000},"page":"1949-1958","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Chemical Fractionation of Phosphorus in Stabilized Biosolids"],"prefix":"10.1002","volume":"37","author":[{"given":"Xiao\u2010Lan","family":"Huang","sequence":"first","affiliation":[{"name":"Dep. of Soil and Water Sciences, Faculty of Agricultural, Food and Environmental Quality Sciences The Hebrew Univ. of Jerusalem Rehovot 76\u2010100 Israel"},{"name":"Cooperative Inst. for Marine and Atmospheric Studies, Rosenstiel School of Marine and Atmospheric Sciences, Univ. of Miami 4600 Rickenbacker Causeway Miami FL 33149"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yona","family":"Chen","sequence":"additional","affiliation":[{"name":"Dep. of Soil and Water Sciences, Faculty of Agricultural, Food and Environmental Quality Sciences The Hebrew Univ. of Jerusalem Rehovot 76\u2010100 Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moshe","family":"Shenker","sequence":"additional","affiliation":[{"name":"Dep. of Soil and Water Sciences, Faculty of Agricultural, Food and Environmental Quality Sciences The Hebrew Univ. of Jerusalem Rehovot 76\u2010100 Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,9]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2004.1062"},{"key":"e_1_2_7_3_1","doi-asserted-by":"crossref","first-page":"179","DOI":"10.2166\/wst.2000.0201","article-title":"Phosphorus losses from sewage sludge disposed on a field: Evidence from storm event simulations","volume":"42","author":"Bossche V.H.","year":"2000","journal-title":"Water Sci.
