Changes in soil P pools during legume residue decomposition

► Legume residues with varying P concentrations were added to a sandy loam soil. ► P dynamics over 56 days were dependant on residue P concentration and plant part. ► Differences among residues on soil P pools were greatest in the first 14 days. ► Roots and shoots had opposite effects on P transformations. ► Part of mineralised P was converted into stable P within 14 days.
