A study of the cationic micronutrient status of soils of district Kishtwar was made at five different cropping systems (Maize –oats, Rice – mustard, Moong –Berseem, Agri - horti system and Vegetable). The DTPA-extractable micronutrient cations and their relationship with different soil properties were studied in different cropping system of Kishtwar district (J&K). Soil samples were collected at a depth of 0-15cm and analyzed for DTPA- extractable iron, copper, zinc, manganese. The DTPA extractable Iron, Copper, Zinc and Manganese ranged from 5.37-23.36, 0.59-4.38, 0.74-2.08 and 4.59-21.08 mg kg-1. Soil DTPA-extractable micro-nutrients, Zn, Cu, Mn, and Fe ranged from 1.24 to 5.55, 1.20 to 2.97, 13.26 to 47.56 and 7.17 to 17.17 mg kg-1 (mean value of 2.34, 2.10, 22.35 and 10.65 mg kg-1), respectively. Correlation between the soil physico-chemical properties and nutrient concentrations showed a significant and positive relationship between CEC and clay content (r=0.827**). Soil pH of the surface layer had a significant and negative correlation with Cu, Mn and Fe (r=-0.281**, r=-0.455**, r=-0.367**). Soil organic carbon showed a significant positive relationship with the available nitrogen, and copper (r= 0.846**, r= 0.256*).
