Abstract: This review paper critically assesses the literature on soil-microbe-plant interactions influencing availability of micronutrients in the rhizosphere. The research entitled <strong>“</strong>Effect of rhizsophere hybridization on macro and micronutrient activities of soil” was conducted during the year 2013-14 in three phases. In the first phase, representative soil samples from rhizosphere of sacred <em>Ficus</em> species (<em>Ficus racemosa</em> L. i.e Umber tree, <em>Ficus benghalensis</em> L. i.e. Banyan tree and <em>Ficus religiosa</em> L. i.e. Pipal tree) and non rhizosphere soil samples were collected and pot culture experiment was carried out to test the germination of sweet orange seeds. In the second phase, pot culture experiment was carried out with nine set of replicated thrice, to study the effect of rhizosphere soil hybridization on growth of sweet orange seedling, soil macro and micro nutrients in soil The growth of sweet orange seedlings was improved in all the rhizosphere and rhizosphere hybridized soils over non rhizosphere and, Sweet orange rhizosphere soil. Amongst all sacred <em>Ficus</em> tree species <em>Ficus racemosa</em> L. rhizosphere soil was best followed by Banyan rhizosphere soil and Pipal rhizosphere soil. Sacred species rhizosphere soil was slightly acidic to neutral in pH, highest content of organic carbon and lowest level of lime. Further the Umber rhizosphere soil recorded maximum content of available N, P, K, etc.
