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. |
