Abstract

 

A study of the macro- and micro-nutrients of some soils of Senapati district, Manipur (India) was carried out to study the soil fertility and micro- nutrient status and their relationship with each other. Surface soil (0 to 30 cm) was investigated for diethylene-triaminepentaacetate (DTPA)- extractable Zn, Cu, Mn, Fe and hot water extractable B in relation to some chemical properties in 20 representative soils. The mean values for DTPA-extractable Zn, Cu, Mn, Fe and hot water extractable B were 2.36, 1.52, 113.93, 766.03 and 0.10 mg kg-1, respectively. The mean values of available N, P2O, K2O and SO4-S were 382.04, 38.31, 208.86 and 22.65 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 in Senapati district.
