In this study, we applied the CENTURY model to predict soil carbon distribution by incorporating observed or predicted spatial soil texture data into the model. Two tillage treatments were studied, Conventional Till and No Till. The simulations using the CENTURY model outperformed field average and multiple regression methods with smaller root mean square error. The CENTURY modeling with observed texture information achieved the best prediction while the modeling with predicted soil texture from terrain attributes showed acceptable results of soil carbon prediction.
