Thirty representative surface (0-15 cm) soil samples were collected from cultivated farmer's field of each taluka of Gir Somnath district viz., Talala, Veraval, Sutrapada, Kodinar, Gir Gadhada and Una during 2014. The chemical analysis of 180 surface samples indicates that soil were deficient with respect to available N and P2O5, whereas medium in available S and high in available K2O status. Among the DTPA extractable micronutrients, Mn and Cu were found sufficient, whereas the soils were medium in Fe and Zn. The nutrient index values were low for available N (1.20) and P2O5 (1.27), medium for available S (1.74), Fe (2.24) and Zn (2.17) and high for available K2O (2.64), Mn (2.79) and Cu (3.00) in the soils of Gir Somnath district.

Abstract


Thirty representative surface (0-15 cm) soil samples were collected from cultivated farmer's field of each taluka of Gir Somnath district viz., Talala, Veraval, Sutrapada, Kodinar, Gir Gadhada and Una during 2014. The chemical analysis of 180 surface samples indicates that soil were deficient with respect to available N and P2O5, whereas medium in available S and high in available K2O status. Among the DTPA extractable micronutrients, Mn and Cu were found sufficient, whereas the soils were medium in Fe and Zn. The nutrient index values were low for available N (1.20) and P2O5 (1.27), medium for available S (1.74), Fe (2.24) and Zn (2.17) and high for available K2O (2.64), Mn (2.79) and Cu (3.00) in the soils of Gir Somnath district.
