Abstract:
The study was conducted to assess the soil fertility status of Godavari delta region of Andhra Pradesh. Soil samples were drawn from four hundred and thirty nine locations of the study area and analysed for physical, physico-chemical, chemical and biological. The results revealed that overall study area was dominant in clay texture with bulk density lower at surface than subsurface. The water holding capacity followed the reverse trend with higher mean values at subsurface than surface with more values recorded in fine textured soils than coarse textured soils. The soils of the study area were found to be slightly acidic to moderately alkaline in nature, normal to critical for germination in electrical conductivity with medium in organic carbon content. Further the area was low in available N, high in available phosphorus in surface and medium in sub-surface soils. Available potassium, calcium, magnesium and micronutrients (Fe, Cu, Mn, Zn) in the soils were high in both surface and sub-surface soil samples.
