Amending litter with acidified biochar may minimize these problems by decreasing litter pH and by retaining litter-derived P, respectively. This study evaluated the effect of acidified biochars from pine chips (PC) and peanut hulls (PH) on NH3 losses and inorganic N and P released from surface-applied or incorporated PL. Poultry litter with or without acidified biochars was surface-applied or incorporated into the soil and incubated for 21 d. Volatilized NH3 was determined by trapping it in acid. Inorganic N and P were determined by leaching the soil with 0.01 M of CaCl2 during the study and by extracting it with 1 M KCl after incubation. Acidified biochars reduced NH3 losses by 58 to 63% with surface-applied PL, and by 56 to 60% with incorporated PL. Except for PH biochar, which caused a small increase in leached NH4+-N with incorporated PL, acidified biochars had no effect on leached or KCl-extractable inorganic N and P from surface-applied or incorporated PL. These results suggest that acidified biochars may decrease NH3 losses from PL but may not reduce the potential for P loss in surface runoff from soils receiving PL.<\/jats:p>","DOI":"10.3390\/ijerph8051491","type":"journal-article","created":{"date-parts":[[2011,5,11]],"date-time":"2011-05-11T11:10:03Z","timestamp":1305112203000},"page":"1491-1502","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":56,"title":["Release of Nitrogen and Phosphorus from Poultry Litter Amended with Acidified Biochar"],"prefix":"10.3390","volume":"8","author":[{"given":"Sarah A.","family":"Doydora","sequence":"first","affiliation":[{"name":"Department of Crop and Soil Sciences, The University of Georgia, 3111 Miller Plant Sciences Building, Athens, GA 30602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel L.","family":"Cabrera","sequence":"additional","affiliation":[{"name":"Department of Crop and Soil Sciences, The University of Georgia, 3111 Miller Plant Sciences Building, Athens, GA 30602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keshav C.","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Biological and Agricultural Engineering, Driftmier Engineering Center, The University of Georgia, Athens, GA 30602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia W.","family":"Gaskin","sequence":"additional","affiliation":[{"name":"Department of Biological and Agricultural Engineering, Driftmier Engineering Center, The University of Georgia, Athens, GA 30602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leticia S.","family":"Sonon","sequence":"additional","affiliation":[{"name":"Soil, Plant, and Water Laboratory, 2400 College Station Road, Athens, GA 30602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William P.","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Crop and Soil Sciences, The University of Georgia, 3111 Miller Plant Sciences Building, Athens, GA 30602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2011,5,11]]},"reference":[{"key":"ref_1","unstructured":"Available online: http:\/\/www.nass.usda.gov\/ga\/ (accessed on 30 April 2010)."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"287","DOI":"10.1023\/A:1009760832696","article-title":"Nutrient losses in surface and subsurface flow from pasture applied poultry litter and composted poultry litter","volume":"50","author":"Vervoort","year":"1998","journal-title":"Nutr.
