A crop residue to fertilize oil palm production

Picture copyright Tao et al.

Nutrient management in oil palm is important for its sustainable development. Scientists Tao et al. used for fifteen years the empty fruit bunch, an oil palm residue, to fertilize palm oil trees in an Indonesian field trial. Applying this residue maintained crop yield and temporal variability while increasing soil organic carbon. Switching from chemical fertilizer treatment to crop residue application is a sustainable practice in the palm oil agricultural management.
