This study starts with the general review on some evidences being found from the soil survey data and recent studies on cation exchange capacity of the paddy soils in Taiwan. The data in table 1. is based on the study on 64 of soil profiles and 183 of soil samples which were classified according to great soil groups, sub-groups and time of sampling. The properties of cation exchange include C.E.C., exchange K, Na, Ca, Mg and H, other physico-chemical properties such as mechanical analysis, PH value, organic matter and total nitrogen are also taken into consideration. There are two main purposes of this study: 1. To discuss the relationship between C.E.C. of the paddy soils of Taiwan and the yield of rice. 2. To explain the C.E.C. in relation with other properties of the paddy soils and to understand its fertility status. The results are shown on the tables in the appendixes.
