Abstract

As a result of expansion of oil palm plantings into marginal soils such as peat and sandy soils the occurance of Cu deficiency has become prominent on these soils. The main characteristics of Cu deficiency are chlorosis necrosis and desiccation of pinnae tips. Affected fronds are shorter and palms show a flat top and stunted appearance. Cu deficient palms have low leaf Cu concentration and high leaf ash and leaf P . The soils tend extremely high organic. C in peat with high C/N ratio and available P apart from the low soil Cu content. The critical leaf Cu concentration is below 2 mg kg and critical soil Cu is below 3 mg kg. Four methods namely foliar spray with 0.025 Cu-EDTA or 0.05 CuSO4 soil application of 75g CuSO4 in planting hole and 100g CuSO4 on soil surface for the first 3 to 5 years root infusion with 15 mg CuSO4 in 50ml water and Cu mudball consisting of 1 kg clay and 100g CuSO4 are recommended.
