In Albania, ultramafic outcrops cover 11% of the surface and the Mg-rich arable vertisols have been estimated to cover about 14,889 ha of the about 700,000 ha of total agricultural land available in the country. Albanian ultramafic landscapes have the potential to provide multiple ecosystem services, but are currently being used for low-productivity agriculture. The purpose of this paper was to characterize Ni availability in one of most Mg-rich arable vertisols of Albania, Field of Domosdova, Prrenjas. We sampled 16 soils from a Domosdova field, which was cultivated with plants that serve as food for animals and humans. Collection of both plant samples (analysis of element concentrations in aerial parts) and soil samples (analysis of total elements), DTPA-extractable Ni, Fe, helped us to evaluate the potential risk of soil elements and the tolerant and accumulator plant species in this serpentine area. Obtained results have revealed high concentration of nickel in soil of the serpentine pastures that are used for animals grazing. Ni availability (DTPA extractable Ni) in Domosdova soil varied from 55 mg kg-1 to 56 mg kg-1. The highest Ni concentrations in were found in nickel hyper accumulator plant Alyssum murale (from 3504 to 3516 mg kg-1). In conclusion, serpentine soil of Domosdova, Prrenjas is a potentially toxic contaminated source to surrounding environment due to the high content of total and available nickel.
