This study was carried out to determine the suitable classification of soil quality forvineyard fields of Akçaköy, Çatalca, Efemçukuru, Görece and Yeniköy villages in Menderesdistrict of Izmir-Turkey. In vineyard fields, soil pH gave a positive relation with Ca andsignificant negative relations with P, Fe, Mn and Zn contents. Soil organic matter (OM)content had significant positive relations with EC, P, Fe, Mn and Zn and significantnegative relations with bulk density and CaCO3 content. Soil quality index values for thevineyard fields varied between 0.38 and 0.85 with a mean of 0.57. Only one of the 28 soilsamples taken from different vineyard fields was found in very suitable (S1:1.00-0.75)class, 8 in suitable (S2:0.75-060), 12 in marginal suitable (S3:0.60-0.50) and 7 in nonsuitable (N:<0.50) class according to the soil quality index (SQI). Restricting soil factors forvine growth in the fields classified in S2 and S3 classes generally became low pH, loworganic matter (OM), P, Fe, Mn, Cu, Mg and K contents than that of suggested levels. Inaddition to restring factors in S2 and S3 classes, physical properties in soils classified in Nclass were lower than suggested levels. The SQI values showed significant positiverelations with grape yield, soil OM, P, K, Fe, Cu, Mn, Zn contents and significant negativerelations with soil pH, exch. Ca and CaCO3 contents. The grape yields had also positiverelations with soil OM, Fe, Mn, Zn contents and negative correlations with soil pH andCaCO3 content. Soil quality in a vineyard field should be assessed to reach successfulsustainable and precision agricultural practices for high crop production.
