Investigations were conducted to examine the effects of different extractants on the amount of zinc extracted from the soils of six locations in Bangladesh. In this study, some extractants such as EDTA, HCl, ASI and CH3COONH4 were selected to use for comparative studies of their extractability to extract soil zinc. The extraction period was set to fix for 4 h for shaking of different soil samples adding with cited above proper reagent in polypropylene centrifuge tube on an end-over-end shaker. Results showed that the maximum amount of Zinc was extracted by using the extractant 0.05 M HCl in Tea, Madhupur, Farm of BAU (Bangladesh Agricultural University) and Poorly drained (Mymensingh). With the action of other reagents, the amount of extractable zinc was very little in all the supplied soil samples. Some exceptions occurred in the case of Ishurdi and Saline soils extracted by EDTA that showed the higher amount of zinc concentration than by the others. CH3COONH4 and ASI exposed to be poor reagents as to effective for the extraction of soil zinc. In the experimental results, it can be concluded that the ability of different extractants to extract soil zinc decreased in the order HCl> EDTA> CH3COONH4 > ASI. |
