Dtpa extractable zinc copper iron and manganese and their uptake by wheat as influenced by varying levels of elemental sulfur



Dtpa extractable zinc copper iron and manganese and their uptake by wheat as influenced by varying levels of elemental sulfur



PKV Research Journal 13(2): 96-99



Incubation study of medium black clayey calcareous soil (Vertic Ustochrept) with the application of elemental sulphur at various levels showed that the addition of elemental sulphur significantly increased the availability of Cu, Fe and Mn and reduced the soil pH from 7.4 to 6.7. The increase in time of incubation also increased the availability of Cu and Fe and reduced the soil pH. The concentration of Zn, Cu, Fe and Mn was increased in wheat plant with the application of various levels of sulphur. However at higher levels there was an adverse effect on the concentration of Zn, Cu and Mn. A significant negative relationship was observed between soil pH and DTPA extractable micronutrients and positive relationship between concentration of micronutrients in wheat plant and DTPA extractable micronutrients.
