Abstract: In this paper, salinization of greenhouse soils in Antalya region was investigated by evaluating findings obtained from three separate studies. Soil samples collected from 105 randomly chosen tomato greenhouses from 9 different locations (Kaş, Kale, Manavgat, Finike, Kumluca, Merkez, Alanya, Gazipaşa and Serik), 35 green pepper and 30 eggplant greenhouses from Kumluca and Kale were analyzed. EC values measured at depths of 0-20 cm and 20-40 cm were classified and evaluated. According to the data obtained the ratio of soils showing different level of salinity (slight, moderate or high level) in tomato greenhouses was 92.9%, in green pepper greenhouses 87.1% and in eggplant greenhouses 66.6%. The highest ratio of moderate and high level saline soils was found in green pepper greenhouses (50.0%) whereas the lowest ratio was in eggplant greenhouses (16.6%). These results suggest that greenhouses being used for, especially, green pepper production are under a potential treat of heavy salinization. Additionally, in this paper, possible solutions for this problem were discussed.
