Abstract

Soils evolve under the state factors such as the parent material, climate, topography, time and the organisms. The duration of soil formation determines soil properties and weathering rates in different ways for instance by changing the physical, chemical and mineralogical properties of soils or by forming a number of different soil horizons. The aim of this study is to determine soil pedogenesis formed on different psychographic units and similar parent materials under semi-arid climatic condition. Study area is characterized with mesic soil temperature regime and xeric moisture regime. Soil formations were highly associated with major psychographic factors and parent materials which are influenced on the morphological and physico-chemical characteristics of the soils. It was observed that soil pedons on alluvial lands were well developed while, pedons formed on eroded lands have weak pedogenesis process. Six soil profiles were classified as Entisol and Inceptisol, according to Soil Taxonomy.

Yarı Kurak İklim Koşulları Altında Farklı Fizyografya, Benzer Ana Materyal Üzerinde Yeralan Toprakların Pedogenesisleri

Abstract

Topraklar ana materyal, iklim, topografya, zaman ve organizmaların ortak etkisi altında oluşurlar. Toprak oluşumu için geçen zaman toprakların özelliklerini etkiler ve onların ayrışma oranlarını belirler. Bu etki zamanla fiziksel, kimyasal, biyolojik ve mineralojik özelliklerin değişimi veya değişik sayılarda horizon farklılaşması gibi olaylarla ortaya çıkar. Bu çalışma yarı kurak iklim koşulları altında farklı fizyografya, benzer ana materyal üzerinde yer alan toprakların pedogenesislerini incelemek amacı ile yürütülmüştür. Çalışma Konya ili Çumra ilçesinde Miyosen marn ana materyalli ve üç farklı fizyografik ünite üzerine yer alan topraklarda gerçekleştirilmiştir. Toprak oluşumları fizyografya ve ana materyalle yakın ilişki içerisindedir. Bu ilişkiler toprakların fiziko-kimyasal ve morfolojik özelliklerini etkilemektedir. Aluviyal ova tabanı ve birikinti yelpazelerde yer alan topraklarda ileri toprak gelişimi gözlenirken, aşınım yüzeyleri üzerinde yer alan topraklar zayıf pedolojik gelişim göstermektedir. Çalışma alanı mesic toprak sıcaklık ve xeric toprak nem rejimlerine sahiptir. Toprak taksonomisine göre altı profil Entisol ve Inceptisol ordolarında sınıflandırılmıştır.
