PEDOLOGICAL DEVELOPMENT ON FOUR DIFFERENT PARENT MATERIALS

摘要: The influence of parent materials on soil properties has long been recognized. Early pedologists and geographers based their concepts soils largely its presumed material. Later, material was viewed simply as a factor that influences development-an diminishes in importance with time. main objective this study is to research the four different some physical, chemical, mineralogical morphological area located Southeast Anatolia Region Turkey. Four profiles were investigated. Soil samples analyzed using standard procedures. results show basalt lime stone-marn derived have relatively deeper profiles, lower bulk density, higher clay content, organic matter, exchangeable bases, micronutrients weatherable minerals. They are also CEC base saturation percentage while available water capacity, hydraulic conductivity natural content more adequate them. around basalt, stone-marn, sand stone alluvium materials. It observed pedons formed well developed while; alluvial deposit weak pedogenesis process. Development B horizons (Bw, Bss Bk) carbonate accumulation pedogenic processes subsurface vertic orhric epipedon top surface. most abundant mineral smectite, followed by illite kaolinite. classified Entisol, Vertisol Aridisol according Taxonomy.
