Status of available micronutrient cations in soils of Kheda district of Gujarat

Abstract

A study was undertaken to assess the status of available micronutrient cations in soils of Kheda district of Gujarat. Total 160 surface (0-15 cm) soil samples were collected from cultivated farmer’s fields of 8 talukas of Kheda district during April-May, 2016. The soil samples were analyzed for DTPA-extractable Fe, Mn, Zn and Cu. The DTPA-extractable Fe, Mn, Zn and Cu content in these soils ranged from 2.31 to 17.83, 3.93 to 18.17, 0.24 to 2.08 and 0.14 to 2.02 with their corresponding mean values of 8.02, 10.11, 1.0 and 0.95 mg kg-1, respectively. Overall, nutrient index values for available Fe, Mn, Zn and Cu were 2.02, 2.44, 2.39 and 2.88 in soils of Kheda district which medium in Fe and high fertility of Mn, Zn and Cu status.
