Sabah, tropical 'metal farm' on ultramafic soil

A shallow ultramafic soil in Sabah: over 90% of the field has more than 2,000 µg/g of total nickel, of natural origin, with a large plant-available fraction and little calcium, potassium and phosphorus.

Phyllanthus rufuschaneyi

Nkrumah, Tisserand, Chaney, Baker, Morel and colleagues set up the first tropical nickel agromining field and studied its soil and the performance of the local candidate species, in the field and in pots.

Outcome Shoots held over 2% nickel by weight and the «bio-ore» obtained was very pure. The paper describes the start of the trial: a fertiliser regime, mass-propagation methods and biomass-processing techniques are still needed.
