Abstract:

Vertical distribution of DTPA-extractable micronutrient cations (Zn, Cu, Fe and Mn) and their relationship with various soil properties were studied in thirty profiles of paddy field of Imphal east and west district of Manipur. The content of DTPA-extractable Zn, Cu, Fe and Mn were higher in surface (0 – 20 cm) horizons and decreased with depth in most of the profiles and ranged from 0.14 to 2.48, 0.26 to 1.26, 1.96 to 21.46 and 2.00 to 24.20 mg Kg-1, respectively. DTPA-extractable Zn was found deficient in 75.56 per cent and sufficient in 22.44 per cent in the soil samples, Cu was found in 81.11 per cent sufficient and 18.89 in deficient and Mn 86.67 per cent was found sufficient and 13.33 per cent in deficient category, While Fe content in the surface soils were well sufficient in all the profile except one profile. Distribution of Zn, Cu, Mn and Fe were influenced positively by OC, CEC, EC, Ca, Mg and N content in the soil. Multiple regression co-efficient analysis showed that DTPA-extractable Zn, Cu, Fe and Mn were influenced by OC, K and N to the level of 44, 40, 21 and 40 per cent, respectively. However, only OC, K and N contributed significantly towards these nutrient cations content in the soils.
