  abstract = {{T}he productivity levels of two arenosol ({A}r40) and fluvisol ({FL}40) fields that had been cultivated for over 40 years were compared to that of fields with the same soils located nearby but never previously cultivated, i.e. {A}r0 and {FL}0, respectively. {A}pplication of poultry manure ({PM}) and sewage sludge ({SS}) were compared to a mineral fertilizer ({T}100), corresponding to 100 kg/ha of nitrogen, over three lettuce ({L}actuca sativa {L}.) crop cycles. {PM} and {SS} were applied at 50 and 150 kg/ha nitrogen equivalent fertilizer doses. {B}iomass production levels in the organic and mineral treatments were similar, except for the {SS}-50 for {FL}0 and the {PM}-150 for {A}r40, {FL}40 and {FL}0. {B}iomass production levels of {A}r40 were higher than those of {A}r0 for the first cycle. {I}n the initial state, the soil {P} content in {A}r40 was higher than that of the {A}r0 soil. {W}ith the treatment repetition, {A}r0 showed the same production level as {A}r40. {F}or the fluvisols, biomass production levels of {FL}40 were lower than those of {FL}0 for the first cycle. {I}ndeed, the initial nitrate content in {FL}40 was lower than in {FL}0. {T}he biomass production levels of {FL}40 were higher than those of {FL}0 for the following cycles.},
