Zinc (Zn) is an established micronutrient required for normal growth and functioning of plants. Its supply in adequate amount is considered indispensable for growth and development of plants. It is primarily taken up from soil through plant roots and translocated to other parts where it is needed to perform its specific role(s). In most cases, the soil (rooting media) have sufficient amount of total Zn, but plants still suffer from its deficiency constraints. Many factors affect and regulate the bioavailability of soil indigenous Zn as well as exogenously applied Zn enhancing bioavailability of the Zn to plants in soil matrix. Among these factors, soil microbial communities play a vital role in enhancing bioavailability of Zn to plants in soil matrix. Similarly, application of bioinoculants has been reported in the literature whose application to soil can promote Zn availability to plants. In this review, all possible strategies which can promote Zn availability to plants have been discussed comprehensively and critically.
