Sensitivity of the CENTURY Model in Predicting Change of Soil Carbon with Different Agricultural Practices
A. Kravchenko, X. Hao *
The CENTURY model has been widely applied to predict change of soil organic matter in agricultural systems. We studied the sensitivity of the CENTURY model to several factors, including soil texture, size of soil carbon pools, precipitation, and temperature. Four management practices, differing in tillage and fertilizer input, were applied. Then statistic method was used to study the interrelationships among these factors.
