The acquired data was used to 1) calculate reference values for the CEC and its components in different soil types, 2) develop pedotransfer functions for predicting the CEC and its components from soil organic C (SOC) and clay contents, pH, and Ca2+, Mg2+, and K+ extracted in standard agronomic soil testing, and 3) develop pedotransfer functions for soil clay and FINES content using the above-mentioned characteristics as explanatory variables.	cache/afs-111107.pdf	txt/afs-111107.txt
