An investigation was carried out to study the soil physico-chemical properties of the sweet orange orchards in YSR district of Andhra Pradesh. To prosecute this investigation, fifty sweet orange orchards aged between 12 to 13 years were selected and soil samples were collected from these orchards at 0-30 cm and 30-60 cm depth. Soil reaction of study area varied widely. Majority of the surface soils samples (72%) were mildly alkaline, but at 30-60 cm depth 48% were strongly alkaline, 38% were moderately alkaline and 14% were mildly alkaline in pH. All the orchards were non-saline in nature. The study area soils were low in organic carbon at surface and sub-surface and decreased with increasing depth. About 70% of surface samples were moderately calcareous, 24% were non-calcareous and 6% were strongly calcareous, but in sub-surface, 74% were strongly calcareous, 24% were moderately calcareous and 6% were non-calcareous. The cation exchange capacity of the surface soils ranged from 24.02 to 64.74 cmol(p+)kg-1, with a mean value of 43.84 cmol(p+)kg-1 and the sub-surface soils varied from 8.74 to 57.69 cmol(p+)kg-1, with a mean value of 38.59 cmol(p+)kg-1.
