- Title
Phosphorus characterization of manure composts and combined organic fertilizers by a sequential-fractionation method.
- Authors
Takahashi, Shigeru
- Abstract
Characterization of the forms of phosphorus (P) in organic soil amendments was conducted by sequential P fractionation. More than 60% of total P was inorganic P (Pi). The major Pi forms in the cattle-manure composts were NaHCO3- and HCl-extractable P fractions. HCl-extractable Pi was the predominant P form and a considerable proportion of the total P was present in the HCl-extractable organic P fraction in the poultry manure composts and combined organic fertilizers.
