Abstract:
In certain cases, it is important to determine empirical relationships among some soil physical and chemical properties. In soil science, such relationships are named pedotransfer functions. For instance, soil total nitrogen (TN) is often determined using cumbersome laboratory tests, but it may be more suitable and economical to develop a pedotransfer function, which uses easily available soil properties. In this study, a pedotransfer function for predicting soil TN from soil organic carbon (OC) was suggested and soil TN was estimated as a function of soil OC. The statistical results of the study indicated that in order to predict soil TN based on soil OC the pedotransfer function TN = 0.026 + 0.067 OC with R2 = 0.83 can be recommended.
