Abstract :This study was carried out to determine assessment of soil quality for olive groves areas of Akçaköy, Çatalca, Efemçukuru, Görece and Yeniköy villages in Menderes district of Izmir-Turkey. The surface soil samples insert ignore into journalissuearticles values(0-20 cm); were taken from 19 olive groves areas of Menderes District. Soil physical and chemical quality indicators were analyzed and classified in 4 suitability classes for olive production. In olive groves areas, soil reaction insert ignore into journalissuearticles values(pH); gave positive correlations with clay, exch. Ca, CaCO3 contents, and significant negative correlations with sand, available Fe, Mn and Zn contents. Soil organic matter insert ignore into journalissuearticles values(OM); content showed significant positive correlations with EC, P, exch. Ca and a significant negative correlation with bulk density. Electrical conductivity insert ignore into journalissuearticles values(EC); values gave significant positive correlations with clay, OM, exch. Ca contents. Soil quality index values for the olive groves areas ranged between 0.44 and 0.77 with a mean of 0.60. The olive groves areas at Akçaköy and Çatalca villages of Menderes District were generally suitable for olive production. According to the soil quality index insert ignore into journalissuearticles values(SQI); values, only one of the 19 olive groves areas was found in very suitable insert ignore into journalissuearticles values(S1:1.00-0.75); class, the other areas were classified as 8 in suitable insert ignore into journalissuearticles values(S2:0.75-060);, 6 in marginal suitable insert ignore into journalissuearticles values(S3:0.60-0.50); and 4 in non-suitable insert ignore into journalissuearticles values(N:<0.50); for olive growth. The most restricting soil factors for olive growth generally became low OM, low nutrient contents and high clay and sand contents than that of suggested levels. The SQI values had significant positive relations with silt content of the soils while they gave negative correlations with clay and sand contents. It indicates that moderate or loamy soil textural classes are important for high olive production. The SQI values also gave a significant positive correlation with olive yields. Evaluation of soil physical and chemical properties with a SQI value is important for assessment of olive groves areas in sustainable soil management system.
