    Abstract: Nutrient management is the key to success in oil palm plantation 
  management, hence in this study soil and plant samples were analyzed to ascertain 
  the nutrient status of some fields in an oil palm plantation in South-South 
  Nigeria for fertilizer application. The results showed that pH values ranged 
  from 4.58-5.85 indicating that the soil samples are slightly acidic, organic 
  matter content ranged from 0.64-2.98%, nitrogen ranged from 0.008-0.143%, p 
  ranged from 1.86-17.50 mg kg<SUP>-1</SUP> while Mg content ranged from 0.08-1.28 
  cmol kg<SUP>-1</SUP>. Statistical analysis showed significant difference in 
  nutrient content of leaf samples analyzed from the critical levels. The results 
  obtained revealed that the nutrient levels in the soil samples were low and 
  application of inorganic fertilizer for faster and better availability of soil 
  nutrients will be required.
