UPDATING SOIL CHARACTERISTICS OF CUKUROVA REGION (SOUTHERN TURKEY) USING GEOGRAPHICAL INFORMATION SYSTEMS AND ILSEN SOFTWARE

摘要

The soil map of cukurova University's (Southern Turkey) campus Adana (1802 ha) was prepared by conventional air-photo interpretation in 1974, and is updated by employing geographical information system and remote sensing techniques. Soils of the campus are developed on alluvial deposits (35%), conglomerates (33%), cakrete (25%) and old river terraces (7%). Soils having 90-120 cm depth cover 26% of the total area whereas shallow soils (10-30cm) occupy 22%. The large area (86%) of region overlay on flat (0-2%) or gently draping lands (2-6%), whereas strongly sloping lands (12-24%) cover only 14%. Four diagnostic horizons were determined as Bw; Ck; Bw-Ck and Bt-Ck with 4%, 21%, 12% and 16% distribution. Land Capability Classification (LCC) I, II and III cover 87.3% of the total geographical area whereas soils of VI and VII class only 12.7%. Soils are classified into Entisol, Inceptisol, Vertisol and Alfisol orders with 16%, 40%, 26% and 18% distribution.
