Abstract

Abstract:

【Objective】Impacting of two soil amendments on the contents of active organic carbon components and soil carbon pool management index were studied from 2015 to 2018 in a sandy fluvo-aquic soil in Langfang City, Hebei Province under wheat-corn rotation. The purpose of the study was to provide a theoretical basis for the higher accumulation of organic carbon in sandy fluvo-aquic soil and for the improvement of soil quality. 【Method】 The experiment was carried out by a single factor randomized block design with four treatments: (1) chemical fertilizer only (CK), (2) CK+ organic amendment 15 t·hm^-2 (T1), (3) CK+ inorganic amendment 2.25 t·hm^-2(T2), and (4) CK+ organic amendment 15 t·hm^-2+ inorganic amendment 2.25 t·hm^-2 (T3). Soil organic matter content, total nitrogen, pH, available phosphorus and available potassium were measured to calculate soil integrated fertility index (IFI) by modified Nemero index method. Active organic carbon pools were also measured to calculate carbon pool management index (CPMI). Both IFI and CPMI were used to evaluate the soil amendments for the improvement of soil quality. 【Result】 The results showed that soil organic carbon (TOC) and IFI increased significantly under organic amendment comparing to CK, especially under the combination of organic with inorganic amendment (T3). The contents of active carbon pools increased under organic amendment, and was in the order of easily labile organic carbon (LOC)> dissolved organic carbon (DOC)>microbial biomass carbon (MBC). The ratio of active carbon pools to TOC decreased under organic amendment: the ratio of easily labile organic carbon to TOC （LOC/TOC） decreased significantly by 12.57% and 12.02% under T1 and T3, respectively; the ratio of microbial biomass carbon to TOC MBC/TOC decreased significantly by 12.84% and 12.30% under T1 and T3, respectively. Inorganic amendment (T2) had no effects on TOC and active carbon pools, therefore, the decreased ratios of active carbon pools to TOC mean that organic amendment increased stable TOC more than active carbon pools. The increase of CPMI and decrease of the ratio of soil carbon pools to TOC under organic amendment (T1 and T3) indicated that organic amendment resulted in the accumulation of organic carbon. The CPMI increased under the organic amendment. Principal component analysis showed that the organic amendment affected the composition and ratio of active carbon pools in the soil. 【Conclusion】 Continuous application of organic amendment significantly improved fertility of sandy fluvo-aquic soil, increased soil carbon pool management index and carbon storage capacity, and ultimately improved soil quality.

Key words: soil amendment, sandy fluvo-aquic soil, fertility factor, soil active organic carbon, carbon pool management index
