Forty soil samples from ten pedons of the Central Telangana region, Telangana were studied for the vertical distribution of DTPA extractable. Zn, Cu, Fe and Mn and their relationship with some soil properties. Soil pH, CaCO3,, organic carbon and particle-size distribution had a strong influence on the distribution of these micronutrients. The content of the micronutrient increased with the an increase in organic carbon and decreased with an increase in pH and CaCO3. There was a decreasing trend for the distribution of these micronutrients with respect to depth. As per the critical limit prescribed for Zn, and Fe, 55 and 12% of the soil could be rated as deficient in available zinc and iron, respectively. Copper and manganese were found to be adequate.
