“The mapping of soil attributes of volcanic ash soils is very important for land use and agricultural practices. An extensive survey was conducted in the soils formed on parent materials erupted from the Erciyes strato volcano, using a systematic sampling strategy with a sampling density of total 192 sampling points. Following the determination of soil variability with geographical information system (GIS), soil maps and geologic maps, soil samples were taken from three different depths (0-30 cm, 30-60 cm and 60-90 cm soil depths) for each sampling location. The maps of soil attributes (Organic matter, pH, calcium carbonate content, cation exchange capacity, exchangeable cations, clay content, silt content and sand content) were produced based on GIS and remote sensing (RS) technologies. A significant spatial relationship was found between soil attributes and soil parent materials using GIS and RS-based analysis.”
