Monitoring of soil fertility and crop productivity in long-term application of fertilizers is necessary to use fertilizers efficiently. This study was conducted to investigate effects of continuous application of lime for rice cultivation from 1969 to 2014. The treatments were no lime treatments (N, NPK, NPKC, and NPKS) and lime treatments (N+L, NPK+L, NPKC+L, and NPKS+L). The application of lime in addition to N, NPK, and NPKC tended to increase pH, exchangeable Ca, and available SiO2. The input of mean annual 1,170 Mg ha<SUP>-1</SUP> yr<SUP>-1</SUP> of lime increased pH 0.0042 yr<SUP>-1</SUP>, 0.0062 yr<SUP>-1</SUP>, 0.0127 yr<SUP>-1</SUP>, and 0.0041 yr<SUP>-1</SUP> in lime treatments (N+L, NPK+L, NPKS+L, and NPKC+L) compared with no treatments (N, NPK, NPKS, and NPKC), respectively. The mean annual Ca field balance varied from 169 to 561 kg ha<SUP>-1</SUP> yr<SUP>-1</SUP> in no treatments, from 871 to 1,263 kg ha<SUP>-1</SUP> yr<SUP>-1</SUP> in lime treatments, indicating that Ca was accumulated in the soils. The mean annual Ca field balance in silicate fertilizer treatments (NPKS, NPKS+L) were higher than that of other treatments because silicate fertilizer included Ca component. Grain yield of rice had no significant differences between no lime treatments and lime treatments. Thus the application of lime led to changes in soil chemical properties but had no impact on the production of rice.
