Influence des caractéristiques du sol sur l'incidence de la Maladie de Panama

En sols acides, le pH et le Ca échangeable sont significativement supérieur là oú la maladie de Panama est absente (horizons moyen et profond). De même, en horizon superficiel, oú le Mg é-changeable est également supérieur. Pas de relation avec K, Na échangeables et P2O5 assimilable. En sols alcalins, la teneur plus élevée en matière organique et la faible densité apparente semblent se recontrer en l'absence de la maladie, de méme que les teneurs les plus élevées en zone assimilable.
