Ultramafic outcrops could represent up to 3% or more of the terrestrial surface and their
unusual geochemistry makes them a global hotspot for biodiversity. Ultramafic soils are a …

The presence of higher-than-normal quantities of nickel is one of the most general features
of ultramafic soils and is often suspected as the reason for their infertility. This study on the …

Ultramafic soils are in equal parts fascinating and dangerous. Developed on rocks derived
predominately from the Earth's mantle and metamorphosed at the ocean floors, ultramafic …

Ultramafic derived soils are characterized by low nutrient soils, a low Ca: Mg ratio, and high
metal contents such as Ni, Co and Cr. The vegetation growing on these soils is highly …

Ultramafic soils are typically enriched in nickel (Ni), chromium (Cr), and cobalt (Co) and
deficient in essential nutrients, making them unattractive for traditional agriculture …

Background and aims Ultramafic soils constitute an extreme environment for plants because
of specific physico-chemical properties and the presence of Ni, Cr, and Co. We …

Ultramafic soils are originated from ultramafic rocks such as peridotite and serpentinite and
are highly enriched in metals (eg, Ni, Cr, and Co) and depleted in plant nutrients (eg, P, K …

Aerial deposition of Ni from a refinery in Port Colborne, Ontario, Canada has resulted in the
enrichment of 29km2 of land with Ni concentrations exceeding the Canadian Ministry of the …

This study aimed at relating the variability of Ni biogeochemistry along the ultramafic
toposequence to pedogenesis and soil mineralogy. Hypereutric Cambisols dominate …

Abstract Background Nickel (Ni) phytomining operations cultivate hyperaccumulator plants
('metal crops') on Ni-rich (ultramafic) soils, followed by harvesting and incineration of the …
