Assessment of block-wise status of micro nutrients in some soils of Shivalik hills of Himachal Pradesh

Abstract

The investigation was undertaken and micro nutrients status of the area was assessed. During February-March 2020, 50 soil sampling locations from tomato growing areas were selected at random and 100 representative surface (0-15 cm) and sub-surface (15-30 cm) soil samples were collected. Various micronutrients, i.e. DTPA-extractable Zn, Cu, Mn and Fe were examined. The soils were neutral to slightly alkaline, and the EC values of all the soil samples were within normal limits. The general state of the soil organic carbon concentration was medium to high. The DTPA- Mn, Fe, Cu and Zn in soils of the studied area were found to be in medium category. Positive correlations between the DTPA-extractable iron, copper, zinc and manganese with the organic carbon content was observed.
