Abstract
Availability of nickel is determined in three fractions (water deionized, DTPA and ammonium acetate), in an incubation study with a calcareous soil. It is observed along the time, a inmovilization of this element in the soil, with a 80-90 % of reduction in relation to initial available concentration of Ni. Besides it is appreciated an incidence of this element on Ca and Mg soluble, incrementing the soluble concentration of this elements proporcionally to inmovilization of Ni.
Key-words: nickel, calcium, magnesium, incubation, availability, movilization.
