Abstract 【Objective】This study was aimed to explore the characteristics of the labile organic matter (LOM) and carbon pool management index (CPMI) under different fertilization in different soil layers in red soil, so as to provide a theoretical basis for carbon pool management in red soil. 【Method】Based on the long-term experiment site located at Jinxian, Jiangxi province, four typical treatments were chosen as: (1) no fertilization (CK); (2) mineral nitrogen, phosphorus, potassium (NPK); (3) NPK combined with pig manure and straw (NPKSM); (4) NPK combined with straw (NPKS). The highly LOM (HLOM), moderately LOM (MLOM), lowly LOM (LLOM), non-LOM (NLOM) and CPMI in four soil depths (i.e. 0-10 cm, 10-20 cm, 20-40 cm and 40-60 cm) were measured and analyzed. 【Result】The results showed that the soil organic matter (SOM) content under each treatment was decreased with increasing of soil depths. Compared with CK treatment, the SOM was increased under the fertilization treatments. In 0-20 cm, the SOM content was ordered as NPKSM >NPKS >NPK >CK, with the highest value as 43.47 g·kg -1(10-20 cm) and 45.09 g·kg -1(0-10 cm) under NPKSM treatment. In 20-60 cm, the SOM content under NPKSM and NPKS was significantly higher than that under CK, while there was no different between NPKSM and NPKS. The dissolved organic carbon (DOC) content was decreased with soil depth under all treatments except NPK. The DOC content under NPKSM and NPKS was significantly higher than that under NPK and CK, and the highest value was 35.93 mg·kg -1under NPKSM treatment. The HLOM, MLOM, and LLOM content were increased under fertilization treatments compared with CK treatment. The LOM content was ordered as LLOM> MLOM> HLOM under the same treatment in same soil layer. All the LOM components content was significantly higher under NPKSM and NPKS treatments in all soil layers. The HLOM and MLOM content under all treatments were trended as first increased and then decreased with increasing of soil depth. The HLOM content was reached to peak in 20-40 cm under NPKSM (5.31 g·kg -1) and NPKS (5.49 g·kg -1). The highest MLOM content appeared in 10-20 cm under NPKSM treatment with 10.62 g·kg -1. The LLOM content under all treatments was decreased with soil depth. In 0-20 cm, the LLOM content was highest under NPKSM treatment with 18.52 g·kg -1(0-10 cm) and 15.93 g·kg -1(10-20 cm), respectively. The proportion of different LOM components and CPMI were increased under the fertilizer treatments. In 0-10 cm, compared with CK, the LOM content under NPKS and NPKSM was increased by 27.9%and 29.48%, respectively, MLOM proportion was increased by 7.21% and 7.72%, respectively, HLOM proportion was increased by 5.10% and 4.96%, respectively. The CPMI under fertilization treatment was higher than 100, and which was obviously higher under NPKSM and NPKS. In 0-20 cm, the different LOM components were extremely significantly positive correlation(P≤0.01), and they were significantly positive correlated with total SOM, total nitrogen, dissolved SOM and rice yield (P≤0.05). 【Conclusion】The SOM and LLOM content under all treatments were decreased with the increasing of soil depth. The SOM and all LOM components were significantly improved under NPKSM treatment, and HLOM and CPMI under NPKSM were the highest, followed by NPKS in 0-20 cm, while, which was the highest under NPKS in 20-60 cm.
