Abstract:
A total 125 surface soil samples (0-22.5 cm) were collected from five talukas of Narmada district using GPS. The soil samples were analyzed for DTPA extractable micronutrients (Fe, Mn, Zn and Cu). The DTPA-Fe varied from 0.65 to 36.8 mg kg^-1 with a mean value 8.45 mg kg^-1, DTPA-Mn varied from 1.06 to 139.36 mg kg^-1 with a mean value 22.24 mg kg^-1, DTPA-Zn varied from 0.07 to 4.46 mg kg^-1 with a mean value 0.77 mg kg^-1 and DTPA-Cu varied from 0.45 to 13.38 mg kg^-1 with a mean value 11.94 mg kg^-1. Out of 125 samples 50.4 percent samples were deficient in DTPA-Fe, 55.2 percent samples were medium in DTPA-Zn and 65.6 percent samples were sufficient in DTPA-Mn content whereas, 100 percent samples were sufficient in DTPA-Cu content. DTPA-Fe (-0.809^**), DTPA-Mn (-0.208^*), DTPA-Zn (-0.301^**) and DTPA-Cu (-0.688^**) showed significantly negative correlation with soil pH and DTPA-Fe (0.312^**), DTPA-Zn (0.187^*) and DTPA-Cu (0.251^**) showed significantly positive correlation with soil organic carbon.
