 Abstract      The relations between the structure variations of a ferrisol and
             those of sugarcane plant parasitic nematode communities were
             studied along three transects. These transects, about 20 m long,
             start in horizon A and end in a levelled area where horizon C
             appears. Results were analysed with the co-inertia analysis method,
              which allowed us to study simultaneously the soil and nematode
             data. Progressive variations of the content of some
             physico-chemical soil elements (organic matter, phosphorus, pH)
             appear linked to progressive variations of the abundance of some
             nematode species (Hemicriconemoides and Pratylenchus). This
             analysis also shows relations that do not vary according to a
             gradient along the transects. For instance, the abundance of
             Helicotylenchus can be paralleled with the existence of high
             calcium grades.
