Economic Implications of Soil on Crop Production in Chandel District of Manipur, India

Kangjam Sonamani Singh and Haribhushan Athokpam


For the analysis of the physico-chemical parameters of the soil of Chandel district, Manipur (India), a study was carried out at 26 villages. Collection of surface soil samples (0 to 30 cm) was done and studied for diethylene-triaminepentaacetate (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 26 representative soils was calculated. The mean values for DTPA-extractable Zn, Cu, Mn, Fe, and hot water extractable B were found to be 0.23, 0.55, 8.87, 22.93 and 0.48 mg kg-1, respectively. The mean values of available N, P2O5, K2O and SO4-S were observed to be 495.7, 15.6, 241.3 and 1.7 kg ha-1, respectively. It was seen that distribution of Zn, Cu, Mn, Fe and B were influenced positively by pH, EC, and organic carbon content of the soil. From the results of the study, it was found that the micro- nutrient cations were significantly correlated with each other suggesting a dynamic equilibrium among them. All the soil samples were sufficient in available micro- nutrient cations, except for zinc.
