The simulation experiment of aerobic composting was adopted to explore the various sulphur (S) fractions change during six manure composting. The total S. various S fractions and available S concentration was markedly different among six manures because of different animal species and diets. Total S concentration decreased especially during 0-14d composting for all manures. The change trend of water-soluble S. adsorbed S and available S concentration firstly increased, then decreased during different manure composting, and the change trend of organic S concentration was opposite to above them. HCl-soluble S concentration has been increasing during composting. High concentration of water-soluble S. adsorbed S and available S was gained as an effective S fertilizer when composting was stopped at 28d. During composting, organic S and HCl-soluble S were main S fractions to affect total S change, and available S could come mainly from water-soluble S and adsorbed S. (C) 2010 Elsevier Ltd.
