Abstract
The DTPA-extractable micronutrient cations Zn, Fe, Cu, Mn and their relationship with different soil properties were studied in 100 surface (0-20 cm) and 100 sub-surface (20-40 cm) soil samples of Kavali revenue division of Nellore district, Andhra Pradesh, India. Zn, Fe, Cu and Mn showed a decreased trend with depth and micronutrients showed positive relationship with organic carbon but inversely correlated with soil reaction.
