Abstract :The aim of this study was to determine how carbon insert ignore into journalissuearticles values(C); mineralization of carob insert ignore into journalissuearticles values(Ceratonia siliqua L., Fabaceae); soils are affected by different temperatures insert ignore into journalissuearticles values(23 °C and 28 °C); and humidity [field capacity insert ignore into journalissuearticles values(FC);, 80% and 60% of their field capacity] conditions in the laboratory. The carob soils were taken from Çukurova University campus in the eastern Mediterranean region of Turkey. C mineralization of all soils was determined using CO2 respiration method. The microbial activity increased together with temperature increases. The microbial activity in the soils humidified at the field capacity and 60% of it was statistically lower compared to the soils humidified with 80% of field capacity at both 23 °C and 28 °C insert ignore into journalissuearticles values(P < 0.000);. The rate insert ignore into journalissuearticles values(%); of C mineralization of 80% of field capacity at 28 °C was significantly higher than field capacity insert ignore into journalissuearticles values(P = 0.009); and 60% of field capacity insert ignore into journalissuearticles values(P = 0.006); at 23 °C and 60% of field capacity insert ignore into journalissuearticles values(P = 0.009); at 28 °C. Based on these results, it is possible to conclude that microorganisms in the carob soil show better activities at 80% of field capacity and 28 °C in 30 days.
