In this study, the assimilation, partition and accumulation of carbon (C) and nitrogen (N), as well as the relationship between C and N accumulation of rice, were studied from typical paddy ecosystems under long-term fertilizer applications with equal N inputs in subtropical China. The results showed that chemical fertilizer plus low organic manure (LOM) could promote effectively the distribution of C in the rice plant. The N content in the stem-leaf and grain of rice under organic-inorganic fertilization was 8.

- Soil samples from Hunan Province were analyzed to understand the effects of different fertilization practices on soil organic carbon and total nitrogen over time.
- Results indicated that soil organic carbon and total nitrogen decreased slightly with no fertilization, remained stable with chemical fertilizers (NPK), and increased significantly with a combination of organic manure and chemical fertilizers.
- Both organic carbon and nitrogen showed a strong positive correlation, suggesting that using organic manure along with chemical fertilizers can enhance soil quality and the interaction between these two components in paddy ecosystems.
