Marginal soils were usually discounted in the past for planting of oil palm. Currently, the en-croachment into these areas is phenomenal as there is no more prime land for oil palm planting in the country. Innovations to counter such limitations have been successful for the cultiva-tion of oil palm but the cost can be high. Nevertheless, on the part of the investors, the higher cost can be offset by the higher returns from oil palm compared to those from other crops. This paper evaluates the potential of selected marginal soils, namely deep peat, tin tailings and steep lands, for the cultivation of oil palm. Specifically, the study assesses the establishment cost of an estate and to a lesser extent the investment viability.
