This study was carried out to determine and evaluate basic soil characteristics and commonly distributed soil types of the Coruh River Basin. Soil groups commonly distributed within the basin were defined according to the USA Soil Classifications System and topographic maps were produced using the ArcGIS 9.3. The Chestnut-Colored soils (107,838 ha) commonly found in the Coruh basin are mainly used for cultivated agriculture, orchards, grassland and pasture and even for forest and shrub lands. Entisols and Inceptisols are common in irrigated and grasslands (2,990 ha); Mollisols in pasture lands (15,551 ha); Mollisols and Alfisols in dry and pasture lands (14,794 ha); Podzol characterized Alfisols and Ultisols in irrigated and dry lands, dry horticulture, pasture, shrub and forest lands (55,455 ha); Lithochromic soils in grasslands (81 ha); Aridisols in pasture lands (430 ha); transported Entisols and Inceptisols in dry lands, horticulture and grasslands (1,797 ha) and Alfisols and Mollisols in dry and pasture lands (46,527 ha). Of the total 326,220 ha of cultivated land in the basin; 290,000 ha is suitable for irrigation.
