Çay Tarımı Yapılan Topraklara Yönelik Faktör Analizi ve Jeoistatistik Uygulamaları: Rize İli Örneği

Abstract

Five factors related with physical and chemical soil properties in tea cultivated areas of Rize province were determined some physical and chemical soil properties were evaluated with factor analysis in this study. These factors explained about 75.63 % of total variables in soil properties of the area. Determined new variables were called as basic cations, microelement, texture, mineralization and fertilization. Basic cations that explained 18.31 % of total variables is the most important variable in new variables wheras, it was found that fertilizer variables is the lowest explain for total variables. Spatial distribution maps of the determined variables in the study area was prepared using geostastistic methods. Kriging maps show that the highest values of the basic cations and microelements were located in high and steep sloped lands whereas, it was found that the highest values of other factors distributed in near the coast area. Especially, high values of the fertilizer distibuted on flat-delta area showed under more human activites.
