Among micronutrients the deficiency of Zn is widespread in Aquic Ustifluvents and Udifluvents of Bihar followed by B. Available Zn, Cu, Fe, Mn and B are significantly and negatively correlated with pH and positively with organic carllon. The step-down multiple regression equation indicate that the availability of Zn and Cu is predominantly controlled by pH and organic carbon whereas Fe and Mn by pH, organic carbon, available P2O5 and K2O, and that of B by pH, organic carbon and EC of the soils.
