This study investigated the effect of liming on B adsorption in different soils from Paraná State, and to correlate these values with some physical and chemical properties of the soils.
Surface samples (0–0.2 m) of nine soils with different parent material and physicochemical properties were used.
Samples with or without lime application were incubated for 60 days.
Boron adsorption was accomplished by shaking 4.0g soil, for 24 h, with 20 mL of 0.01 mol L–1 CaCl2 solution containing different concentrations of B (0, 1, 2, 4, 8 and 16 mg L–1).
Sorption was tted to non-linear form of the Langmuir adsorption isotherm. Boron adsorption increased as concentration increased.
Maximum adsorption capacity (MAC) of B ranged from 2.3 to 42.9 mg kg–1 (without lime) and 22.7 to 109.9 mg kg–1 (with lime).
The two Arenic Hapludalf have had the highest B adsorption capa...
