  abstract = {{S}oil type and changes in soil properties due to long-term fertilizer application are each known to alter phosphorus ({P}) availability. {O}ur aim was to determine the respective effects of soil type and fertilizer application on the available {P} content and proportion of inorganic {P} ({P}i) vs. organic {P} ({P}o). {F}ive field trials where mineral and organic fertilizers were applied for a decade along a toposequence (two andosols, one andic cambisol, one nitisol and one arenosol) were investigated. {L}egacy {P} (i.e. {P} accumulated in soil with fertilizer applications minus {P} lost by plant uptake, erosion and leaching) was used to study the effect of fertilizer application rate. {P} availability was determined by classic extractions and by the diffusive gradients in thin films technique ({P}i-{DGT}). {T}he solid-solution {P}i ({K}d) partitioning coefficient was determined to assess the soil {P}i sorption capacity. {K}d decreased from the andosol (median: 3231 {L}/kg) to the arenosol (median: 103 {L}/kg), suggesting a decrease in {P}i sorption with the soil evolution. {I}n addition, {K}d decreased with increasing p{H} for all soil types and with increasing content of organic carbon for the arenosol, showing that {P}i sorption capacity changed with the changes in soil properties induced by fertilizer application. {P}i-{DGT} (from <0.01 to 0.27 mg/{L}) and {P}i-water (from <0.1 to 40.7 mg/kg) changed with the soil type and fertilizer application rate. {O}ur study suggests that advice for {P} fertilizer management should integrate the effects of repeated fertilizer application on soil p{H} and organic carbon content, which change soil {P} availability.},
