Biogeochemical implications of labile phosphorus in forest soils determined by the Hedley fractionation procedure

  title={Biogeochemical implications of labile phosphorus in forest soils determined by the Hedley fractionation procedure},
  author={Arthur H. Johnson and Jaqueline Frizano and David R Vann},
Forest ecologists and biogeochemists have used a variety of extraction techniques to assess labile vs. non-labile soil P pools in chronosequences, the balance between biological vs. geochemical control of P transformations across a wide range of soil orders, the role of plants with either N-fixing or mycorrhizal symbionts in controlling soil P fractions, and to make inferences about plant-available P. Currently, variants of the sequential extraction procedure developed by M. J. Hedley and co… CONTINUE READING
