Litter bag method was conducted to investigate the decomposition characteristics of rice straw (6000 kg ha-1) and its associated microbial community under different nitrogen (N) addition rates (0, 90, 180 270 N double-rice rotation. Generally, mass reduction nutrient release were faster in early stage (0-14 days after decomposition), when easily-utilized carbohydrates amines preferential substrates for involved decomposers. Straw-associated N-acetyl-glucosamidase L-leucine aminopeptidase...
Abstract Considering the close connection between soil microorganisms with carbon (C) cycling, aim of this study was to identify specific bacterial and fungal microbes that assimilate 13 C from incorporated rice straw explore their dynamics characteristics during decomposition in paddy soil. Soil microcosms based on 12/13 C‐labeled were incubated determination CO 2 production at 1, 3, 7, 14, 28, 56 90 days after incorporation. Meanwhile, targeted communities characterized using a DNA‐based...
Abstract Despite the vast carbon (C) stock of crop root residues in arable ecosystems, microbial assimilation mechanism derived‐C is poorly understood. In this study, a DNA‐based stable isotope probing (DNA‐SIP) approach was used to explore and characterize diversity soil bacterial community assimilating C derived from 13 C‐labelled rice during 90‐day incubation. Overall, C‐assimilating groups with various characteristics were identified occurrence strong priming effects on native C....
Abstract To elucidate the identity and mechanisms by which specific bacterial members drive efficient decomposition utilisation of straw, succession co‐occurrence patterns 13 C‐labelled bacteria were analysed using DNA‐stable isotope probing (SIP) techniques. Microcosms with maize straw incorporated into soils subjected to no nitrogen (N) fertiliser (CK), chemical (NPK) return (NPKS) treatments for 8 years incubated 360 days. The results showed that fertilisation regimes changed groups...
Knowledge of the spatial-temporal variations soil organic carbon (SOC) quantity and quality its microbial regulation mechanisms is essential for long-term SOC sequestration in agroecosystems; nevertheless, this information lacking process walnut plantations. Here, we used modified Walkley-Black method, phospholipid fatty acid analysis, micro-plate enzyme technique to analyze evolution stocks quality/lability as well communities activities at different depths plantations with a chronosequence...
Quantifying greenhouse gas intensity (GHGI) and soil carbon sequestration is a method to assess the mitigation potential of agricultural activities. However, effects different fertilizer amendments on net GHGI in rice-wheat cropping system are poorly understood. Here, treatments including PK (P K fertilizers); NPK (N, P fertilizers), + OM (NPK plus manure), SR straw returning), CR controlled-release fertilizer) with equal N input were conducted gain insight into change organic (SOC) derived...
Organic-inorganic fertilizer combination plays a vital role in improving soil quality and decreasing dependency on mineral fertilizers. However, existing research predominantly focuses short-term effects, leaving the mechanisms of long-term impacts substituting chemical nitrogen with straw organic fertilizers fluvo-aquic remains unclear, particularly regarding contributions biological abiotic quality. This study systematically investigates changes physicochemical properties, aggregates,...
As the largest organic carbon input in agroecosystems, crop residues can increase soil sequestration and production greenhouse vegetable fields (GVFs). However, microbiological mechanisms driving straw decomposition GVFs under different incubation temperatures fertilization treatments are not clear. Thus, samples were collected from a long-term field experiment included chemical fertilizer application alone (CF), 2/4 N+2/4 N (CM), N+1/4 (CMS), (CS), incubated with
