Oil palm plantation research. Workers carrying out research at an oil palm (Elaeis guineensis) plantation, in Sumatra, Indonesia. A radioactive marker (rubidium) solution is placed in contact with the trees' roots and the movement of the marker through the plants tissues is then tracked to assess the efficiency of the root system. The fruit of the oil palm contains oils that are used in many food products and non-food household products. It is also potentially useful for the production of biodiesel. Though native to West Africa, this species of palm has been successfully introduced to many tropical regions. In Indonesia, the cultivation of oil palms has led to a significant loss of rainforest and decrease in biodiversity, however this plantation is.
