Carbon stocks are calculated between from 0 - 100 cm depths of Adana great soil groups (GSG). Total carbon stock is 567.19 Tg in 0 - 100 cm, 168.37 Tg of which is organic carbon (OC) and 398.83 Tg of which is inorganic carbon (IC). While 77.81% of soil organic carbon consists of alluvial, brown and non-calcareous brown forest soils, 59.77% of soil inorganic carbon (SIC) consists of alluvial, colluvial and brown forest soils. Organic carbon stocks are mostly seen in non-calcareous brown forest soils (53.75 Tg or 31.92% of OC stocks, 22.61% of all area). The least stock is determined in alluvial coast soils (0.02 Tg or 0.01% of OC stocks, 0.01% of all area). Inorganic carbon stocks are mostly found in alluvial soils (165.7 Tg or 41.65% of SIC stocks, 19.88% of all area) and it is least seen in alluvial coast soils (0.12 Tg or 0.03% of SIC stocks, 0.01% of all area). While soil organic carbon amount is between 6.01 - 13.78 kg C m-2, soil inorganic carbon amount changes between 26.27-60.01 kg C m-2. Generally, it is seen that soil organic carbon amount is low in the area where intense agriculture techniques are used and it is high in meadow and forest areas which form high areas.


Key words: Adana soils, soil organic carbon amounts and stocks, soil inorganic carbon amounts and stocks.
