Metals sorption on solid phase from solution is one of the most important chemical processes controlling their bioavailability in soils. Nickel (Ni) sorption characteristics in 20 calcareous soils of Iran were investigated in a range from 5.87 to 751.23 mgL-1 Ni concentration in solution using sorption isotherms. Ni sorption isotherm exhibited strong nonlinear behavior for all soils. The results revealed that Ferundlich, Langmuir and Ridlich-Pterson isotherms well described Ni sorption on soils (r2= 0.92-1.00, r2= 0.94-0.99 and r2= 0.94-1.00 for Freundlich, Langmuir and Ridlich-Pterson models respectively). The maximum Ni adsorption (qmax) ranged from 1369 to 5378 mg kg-1 which positively correlated with organic matter (r2=0.50, p
