Chemical properties and available zinc status in soils coming under paddy land use cover of Bhadra command, Karnataka

Abstract

A study was conducted to assess the available zinc status in soils under paddy land use cover of Bhadra command, Karnataka. One hundred and forty-five soil samples were collected from seven different taluks coming under paddy land use cover of Bhadra command and analyzed for physical and chemical properties and available zinc status. Considering 0.60 mg kg-1 as the critical limit of DTPA zinc in soils, 70.34 and 29.66 per cent samples were found to be sufficient and deficient in available zinc, respectively. Sufficiency in available zinc status attributed to regular addition of ZnSO4 to soils for every season of paddy. Further, it is also influenced by pH, organic carbon and CaCO3 content of the soils.
