Faktör Analizi ile Minimum Veri Setinin Oluşturulması ve Haritalanması: Samsun İli Örneği

Abstract

The main objective of this study is to create minimum data base and mapping using factor analysis. 889 soil samples were collected from Samsun province and 17 physico-chemical properties of them were evaluated. In this study, 0.5 was obtained as the lowest factor value for variables. To increase success of factor analysis, electrical conductivity, lime content, extractable calcium and extractable cupper that was not assigned to any factor as variable were not incorporated in factor analysis. After factor analysis, 5 variables were selected and these variables were called as availability of micro nutrients, texture, sedimentation, organic matter and risk of alkalinity were called. Whereas selected 5 factors explain about 72.36% of total variables belonging to physicochemical properties, availability of micro element factor explain about 20.07% that was found the highest ratio in variables of soil properties. Spatial distribution maps was prepared using kriging methods for factors. It was seen that these maps showed about strong and weak zones of factors for Samsun’ soils.
