Abstract: Boron (B) is an important micronutrient in plant nutrition supply from the soil solution which is highly governed by the pools of B and their equilibrium with the soil solution. The concentration of B and their forms are widely distributed in soil horizons under different depths. The physico-chemical properties of the soil have profound effect on these different forms of Boron. An experiment was conducted to assess the response of different soil attributes to the B dynamics influencing the pattern of distribution in soil. Samples collected from the identified series of two soil orders namely Alfisol and Entisol. Results revealed that the relative proportion of various fraction of boron in soils are in the following order i.e. readily soluble B< Specifically adsorbed B < Organically bound B < Oxide bound B < Residual B. The soil attributes like pH, organic carbon, texture, CEC, extractable-Al, exchangeable-Al, CBD-Fe, CBD-Al, amorphous-Fe and Al influence the fraction of boron to a various extent.
