This study was carried out to investigate the effect of the annual application of organic resources on the soil environment and rice production. The experiment consisted of five treatments; NF (no-fertilization), NPK (inorganic fertilizer), NPKR (inorganic fertilizer + rice straw), NPKC (inorganic fertilizer + cow compost) and NPKS (inorganic fertilizer + swine compost). Soil organic matter content was not different for all treatments in 2021. The soil organic carbon (SOC) and soil organic carbon stock (SOC stock) were not difference for all treatments in 2021. The highest rice production was NPKR treatment in 2018 and 2021. However, the rice production was no significant difference among the other organic resource application treatments (NPKR, NPKC, NPKS) and only inorganic fertilizer treatment. The application of organic resources can improve the soil environment and increase crop production. Still, long-term studies are needed to evaluate the impact of the application of organic resources on the soil environment and crop production.
