Abstract

Abstract:

【Objective】 The effects of long-term fertilization on the distribution of organic carbon (OC) and total nitrogen (TN_OIC) of organo-mineral complexes in red paddy soil were studied, so as to provide a basis for long-term management and cultivation of soil fertility in red paddy soil. 【Method】 The red paddy soils in long-term fertilization experiment were studied (Since 1984), which included four treatments: no fertilization (CK), inorganic P and K fertilizers (PK), inorganic N, P and K fertilizers (NPK), and NPK plus manure (NPKM, 70%NPK plus 30% manure). Soil samples of 0-20 cm soil layer were collected, and the distribution of organo-mineral complexes at each particle level (<2 μm, 2-10 μm, 10-20 μm, 20-50 μm, and 50-250 μm) was analyzed. The effects of fertilization on the content, storage of organic carbon and total nitrogen as well as the carbon-nitrogen ratio (C/N) were discussed. The effects of OC and TN_OIC contents in organo-mineral complex on contribution rate of SOC and TN contents in red paddy soil were investigated too.【Result】 Compared with the CK treatment, the fertilization treatment significantly increased the particle size ratio of 20-50 μm and decreased the particle size ratio of <10 μm. Compared with other fertilization treatments, NPKM treatment increased the proportion of 50-250 μm grain size complex more significantly. Different fertilization treatments had different effects on the content of OC and TN_OIC in grain size. Compared with PK, the content of OC and TN_OIC in grain size from 50 μm to 250 μm under NPK treatment increased 36.3% and 80.6%, respectively. Compared with NPK, the content of OC and TN_OIC in 50-250 μm granular complex increased by 35.4% and 19.5% under NPKM treatment, respectively. The OC and TN_OIC storage of the organic and inorganic complexes were mainly distributed at the 10-20 μm particle level. And fertilization significantly reduced the storage of <2 μm particle-level complex OC and TN_OIC, but increased the storage of OC and TN_OIC at 20-50 μm particle-level. Compared with PK treatment, the OC storages of <2 μm and 50-250 μm particle-level complexes treated by NPK increased by 18.5% and 31.2%, respectively, and the storages of TN_OIC increased by 18.8% and 73.7%, respectively. Compared with NPK, the NPKM treatment reduced the OC and TN_OIC storages of the <2 μm particle-level complex by 25.6% and 27.4%, respectively, while OC and TN_OIC storages of 50-250 μm particle-level complex increased by 56.3% and 38.6%, respectively. Fertilization significantly influenced the C/N ratio of 50-250 μm particles. Compared with PK, the C/N ratio of 50-250 μm fraction treated with NPK decreased by 24.6%; compared with NPK, the C/N ratio of 50-250 μm fraction treated with NPKM was increased by 13.4%. Fertilization significantly affected the contribution rate of organo-mineral complexes of each particle size to SOC and TN content. Compared with PK, the contribution rate of NPK treatment 50-250 μm particle-level complex to SOC and TN increased by 17.4% and 47.4%, respectively. Compared with NPK, the contribution rate of NPKM treatment 50-250 μm particle to SOC and TN were reduced by 39.5% and 32.8%, respectively.【Conclusion】 In red paddy soil, the long-term fertilization promoted the formation of large-grain organo-mineral complexes. The nitrogen input in the chemical fertilizers significantly increased the grain-level organic carbon, total nitrogen content and storage of the granular grade of 50-250 μm. The organo-mineral combined application was conducive to increasing the soil organic carbon content and the proportion of large-grain organo-mineral complexes, which was helping to preserve the inorganic nitrogen fertilizer application. Therefore, organic and inorganic compound application was an effective measure for long-term fertilization management of red paddy soils.

Key words: long-term fertilization, red paddy soil, organo-mineral complex, organic carbon, total nitrogen
