The Effect of Physiographical Change on Profile Development and Soil Properties

Abstract

The transformation of rocks and organic inputs into parent material and soil is a dynamic process controlled by physical, chemical and biological factors. In this process, the parent material, climate, topography, organism and time are known as formation factors. The differences in physiography cause variability in soil properties with the effect of other formation factors. In this study; It is aimed to reveal how the physiographic variability is reflected in the profile morphology and the statistical effects of this reflection on soil properties. Morphological descriptions of four soil profiles (PI, PII, PIII, PIV) were made in the north-south direction to represent the varying physiographic units (shoulder, toeslope, backslope) and some physical and chemical properties of soil samples taken on the basis of the horizon were determined. In addition, the variables in soil properties were evaluated with some statistical parameters. As a result of the study, all profiles were classified as Lithic Xerorthent / Petrocalcic Leptosol. While the profiles on the upper and lower skirts have similar characteristics, it has been determined that the profile in the low plain differs in terms of horizon depth and thickness, soil color, lime content, texture and water characteristics. With this study, it has been revealed that the relationship can be explained more clearly as a result of the evaluation of the change in soil properties with statistical approaches.
