Determination of soil fertility status of orange grown gardens in Manavgat district of Antalya province

F.O. Asri
This study aimed to investigate the nutritional status of orange orchards in the Manavgat region in Antalya. The soil and leaf samples were collected from 25 different orange orchards. The analyses were made to determine pH, electrical conductivity (EC), lime (CaCO3), texture, organic matter, total nitrogen (N), available phosphorus (P), available potassium (K), calcium (Ca), magnesium (Mg), available iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) in soil samples and total N, P, K, Ca, Mg, Fe, Zn, Mn and Cu in leaf samples. The critical levels for the nutrients of the leaf and soil samples were compared and the nutritional status of each orange orchard was determined against the findings. Results indicated that most of the soils were loam, slightly alkaline and alkaline, highly calcareous, and poor in organic matter, without any salinity problem. Soil total N, available P, exchangeable Ca and Mg, and available Fe, Mn, and Cu concentrations were found to be sufficient. In terms of the concentrations of leaf N, P, K, Mg, Zn, and Mn were insufficient respectively 76, 40, 52, 40, 96, and 92%. The concentrations of leaf Ca, Fe and Cu was generally sufficient.
