Soil samples were analysed to improve the fertility of paddy soils in Yongnam district during the years from '81 to '82. It was found that available P2 O5 (113 ppm) and extractable potassium (0.25me/100g) slightly increased compared to values observed during years from '64 to '69 while the contents of O.M., extractable Ca and Mg etc slightly decreased, and the values of pH, C.E.C. and Av. SiO2 etc. were more or less unchanged
