Micronutrient Status of Some Soils of U. P. Hills

Total and available status of iron, manganese, copper, zinc, molybdenum and boron in the hill soils of Uttar Pradesh were determined. Of the soils, 17.3% in Fe, 20% in Mn, 20% in Cu, 74.6% in Zn, 24% in Mo and 18.6% in B were defficient on the basis of total sample analysed. A significant negative correlation between pH on one hand and available Fe, Cu and Zn indvidually on the other was obtained. Significant and positive correlations between pH and available Mn and also beween org. C and available Fe or available Mn were noticed. However, org. C correlated negatively and significantly with available copper, zinc and molybdenum. CaCO₃ had significant and negative relationship with available Fe, Cu and Zn and a significant positive correlation with Mn. Electrical conductivity gave significant and positive correlation with available Fe, Mn, Cu and B, while it had significant and negative correlation with Zn. All the available micronutrients gave significant and negative correlation with altitude.
