A study was carried out in both the laboratory and in the field to determine the effects of POME (palm oil mill effluents) application on soil chemical properties important for plant growth. The samples under treatment were analysed after 2, 4 and 6 months. The results of the laboratory study showed that POME increased organic matter content, pH and negative charge and lowered pH and aluminium saturation. On the other hand, the field study did not show any significant difference between the treated soils and the control. Irreversible drying was suggested to be the cause. A suitable method of land application which may improve its effectiveness is suggested.
