abstract:
The fractionation of inorganic phosphorus was made in six bottom sediments of kettle holes located on areas of different agricultural use. The extractions performed allowed to isolate the following fractions: dissolved or water soluble P, reduced soluble P (bound to Fe an Mn oxides), NaOH-extractable P (bound to Al and humic acids), and HCl-extractable P (apatite phosphorus). Organic matter content and pH of the sediments were also analysed. Significant correlation were found between the tested parameters.
