摘要

In this study, soil samples were taken from 32 different locations from two different soil depths (0-30 and 30-60 cm) and 16 physical and chemical soil properties were assessed through factor analysis (FA) and geographical information systems (GIS). FA revealed 5 factors for the surface soil depth (0-30 cm) explaining 79.58% of total variation in data set. These factors were entitled as factor 1 "soil water holding capacity", factor 2 "microelement availability", factor 3 "organic matter", facto
