| 英文摘要 | Integrated crop-livestock systems and organic manure application are vital strategies for sustainable agriculture. Understanding carbon (C) and nitrogen (N) cycling from crops, through animal digestion to manure, and subsequently to soil is essential. However, studies on these processes remain scarce due to high costs and technical complexities associated with preparing dual-labeled (C-13 and N-15) manure, which deter researchers from conducting such experiments. Our study pioneers dual-labeled manure preparation and provides a methodological framework for simultaneously tracing C and N cycling from feedstuffs to manure in long-term nutrient cycling research. Key findings include the distribution of C-13 and N-15 across different maize components (kernel, cob, leaves, stalk, and root), and goat manure, and compost. The study revealed the transformation and recovery of C and N from maize to manure. For instance, 31.7% of manure C and 27.3% of manure N originated from maize feed, with 11.8% of feed C-13 and 28.6% of feed N-15 recovered in manure, and 16.5% and 25.8% recovered in compost, respectively. Composting enhanced C retention and stabilized N, improving nutrient cycling efficiency. While no correlation between C-13 and N-15 was observed in maize tissues, a strong linear relationship (R-2 = 0.9908, p < 0.001) was identified in goat manure during a 10-day feeding period. These findings provide a foundation for future studies tracing C and N cycling from manure compost, invaluable for refining C and N cycling models. Future studies should extend the tracing period across diverse crop-livestock systems to validate these findings. |
