Bu çalışmada, Orta Anadoluda yan kurak iklim bölgesinde yer alan Çankın-Kızılırmak ovasında tanımlanan beş tipik Kuatemer toprak profilinin fiziksel, kimyasal ve morfolojik özellikleri araştırılmıştır. Çalışılan topraklar Kızılırmak Nehri'nin Kuaterner'de depoladığı genç aluviyal ana materyaller üzerinde oluşmuştur. Farklı yörelerden taşınıp getirilen aluviyal toprakların karmaşık fiziksel, kimyasal ve mineralojik bileşim içerdiği gözlenmiştir. Çukur topografyalarda yer alan bazı topraklarda tuzlulaşma ve aUcalileşme proplemi görülmektedir. Toprak profilinde tuz akumulasyonunu gösteren yoğun tuz kristalleri gözlenmiştir. Çalışılan beş toprak profili Toprak Taksonomisi' ne göre Vertisol, Entisol ve Aridisol olarak sıruflandınlmıştır.

In this study; chemical, physical and morphological properties of five typical quaternary soil pedons, collected from Çankın-Kızılırmak Plain, a semiarid region in Mid-Anatolia, were studied These soils pedons developed on young alluvial deposits carried and accumulated by Kızılırmak River in Quaternary. It was observed that the alluvial materials carried and deposited from different directions bear complex physical, chemical and mineralogical contents. Salinity and alkalization problems are observed in some quaternary soils, that is under the influence of ground water, that belong to cave topography. In the soil profiles, salt crystals were observed intensively, indicating salt accumulation. The accumulation of salt in the two soil pedons is at such a rate that develops the Salic horizon formation. No problem of salinity and alkalization occurred in the other pedons. Formation of soil in lands on old river terraces is in a further level, and a Cambic B definition horizon is developed. Metamorphosis of horizon in soils which formed on young alluvial deposits is not clearly identified. The five soil pedons have been classified with respect to Soil Taxonomy as Vertisol, Aridisol and Entisol.
