To study the soil fertility and micro-nutrient status and their relationship with each other, a study of the macro-and micro-nutrients of some soils of Chandel district, Manipur (India) was carried out. Investigation of 26 samples of surface soil (0 to 30 cm) was done for diethylene-triamine penta acetate (DTPA) - extractable soils. The mean values for DTPA-extractable Zn, Cu, Mn, Fe and hot water extractable B in relation to some chemical properties in the soils. The mean values for DTPA-extractable Zn, Cu, Mn, Fe and hot water extractable B were 0.23, 0.55, 8.87, 22.93 and 0.48 mg kg-1, respectively. The average values of available N, P2O5, K2O and SO4-S were found to be 495.7, 15.6, 241.3 and 1.7 kg ha-1, respectively. Distribution of Zn, Cu, Mn, Fe and B were influenced positively by pH, EC and organic carbon content of the soil. Results indicated that the micro- nutrient cations were significantly correlated with each other suggesting about the dynamic equilibrium among them. All the soil samples were sufficient in available micro- nutrient cations except zinc.
