Zinc (Zn) deficiency is a widespread phenomenon globally. Conventional Zn fertilizers viz zinc sulfate (ZnSO₄· 7H₂O) reported to have very low use efficiency (1–5%). Hence, technological interventions in increasing Zn use efficiency are of utmost important. Keeping this in view, a laboratory incubation study was undertaken to evaluate the effect of various Zn carriers on release kinetics of zinc and iron under Inceptisol and Alfisol. Zincated nanoclay polymer composite (ZNCPC), nano zinc oxide (n-ZnO), Zn-citrate were compared with conventional one i.e., zinc sulfate. ZNCPC attributed highest DTPA-Zn content at 45 days of incubation in Inceptisol (2.99 mg kg⁻¹) and at 60 days of incubation in Alfisol (2.36 mg kg ⁻¹). Zn citrate was found another efficient Zn carrier followed by ZNCPC but superior over n-ZnO as per as the Zn availability and control release behavior is concern. Thus, ZNCPC was found to be the most efficient Zn carrier as compared to conventional zinc sulfate and other nano Zn carriers. High aspect ratio of n-ZnO curbs its soil application.

锌（Zn）缺乏症是全球普遍存在的现象。据报道，传统的锌肥料即硫酸锌（ZnSO ₄ ·7H ₂ O）的使用效率非常低（1-5％）。因此，提高锌使用效率的技术干预至关重要。考虑到这一点，进行了一项实验室培养研究，以评估各种Zn载体对Inceptisol和Alfisol下锌和铁的释放动力学的影响。锌取代的纳米粘土的聚合物复合物（ZNCPC），纳米氧化锌（Ñ -ZnO），锌-柠檬酸盐用以往相比即硫酸锌。ZNCPC认为在Inceptisol中孵育45天时DTPA-Zn含量最高（2.99 mg kg ^-1）和在Alfisol（2.36 mg kg ^-1）中孵育60天。发现柠檬酸锌是另一种有效的锌载体，其次是ZNCPC，但考虑到锌的有效性和控制释放性能，其优于n -ZnO。因此，与常规的硫酸锌和其他纳米锌载体相比，ZNCPC被认为是最有效的锌载体。高纵横比的n- ZnO限制了其土壤应用。
