Tjoa et al. 2023 - Nickel acquisition affected by root density of mono- and mixed-cropping peanut and choy sum
This experiment measured nickel acquisition in peanut and choy sum shoots grown in limonitic laterite soil under mono- and mixed-cropping conditions.
Key numbers
Source units are mg/kg.
- Limonitic laterite soil Ni concentration: 7.884.
- Monocropped peanut shoots: 20, 90, and 120 in small, medium, and big pots.
- Monocropped choy sum shoots: 51, 67, and 95 in small, medium, and big pots.
- Mixed-cropped peanut shoots: 33, 50, and 51 in small, medium, and big pots.
- Mixed-cropped choy sum shoots: 15, 52, and 63 in small, medium, and big pots.
Methods
The study grew peanut and choy sum in pots containing 0.5, 1.0, and 1.5 kg of limonitic laterite soil and analyzed Ni in shoots.
Implications
This is experimental plant-uptake context rather than market-basket occurrence. It is still useful for nickel-contamination mechanism notes in vegetables grown on ultramafic/lateritic soils.

Verification notes
- Source identity checked against DOI 10.24259/jpkwallacea.v12i1.26615 and the downloaded PDF.
- The PDF states the limonitic laterite soil contained 7.884 mg kg-1 Ni; this value is preserved as printed in the source.
- The source reports shoot concentrations, not finished edible retail samples; route with experimental context preserved.
