A laboratory incubation study was conducted to study the influence of liming on extractable boron (B) in acidic soil. Six soils, three each from the Inceptisols and Alfisols, were incubated for 30days with combinations of lime and B. The soils were acutely deficient in plant-available B (0.09-0.21mgkg(-1)). Only <50 percent of applied B was recovered from the soils in available form. Such recovery was lower in Alfisols than that in Inceptisols due to adsorption of a greater amount of added B with iron (Fe-) and aluminium (Al-) oxides in the former soil group. Required dose of lime showed an increase in availability of native soil B, particularly in Inceptisols (26 percent), and a net decrease in recovery of added B (32.5 percent) as compared to no lime control (41.6 percent). The results thus suggest that liming to acidic soils increases extractable B.
