Abstract With increasing livestock breeding, methane (CH4) emissions from manure management will increasingly contribute more to atmospheric CH4 concentration. The dynamics of methanogens and methanotrophs have not yet been studied in the environment. current study combines surface with methanogenic methanotrophic community analyses two practices, windrow composting (WCOM) solid storage (SSTO). Our results showed that there was an c. 50% reduction WCOM compared SSTO over a 50-day period. A...
Humic acid (HA) has an inhibitory effect on phytopathogenic fungi, but the structure–activity relationship remains unclear. HAs were extracted from 14 different materials, and their fungistatic activities elemental C, N, S, O contents measured. Cross-polarization magic-angle spinning 13C nuclear magnetic resonance (CPMAS NMR) was used to measure organic carbon composition. The results showed that all suppressed fungi growth, with Yunnan lignite showing highest inhibition (85.3%) against...
Nitrogen (N) deep placement has been found to reduce N leaching and increase use efficiency in paddy fields. However, relatively little is known how bacterial consortia, especially abundant rare taxa, respond placement, which critical for understanding the biodiversity function of agricultural ecosystem. In this study, Illumina sequencing ecological models were conducted examine diversity patterns underlying assembly mechanisms taxa rice rhizosphere soil under different fertilization regimes...
Fungistatic activity is a newly identified ecological function for soil humic acids. However, the relation between fungistatic activities of acids and their chemical structures still unclear. In addition, how fertilizer application affects unknown. We sampled paddy soils with different long‐term schemes, namely: unfertilized control (CK), mineral applied (NPK) plus straw return (NPKRS). Soil were extracted against 14 phytopathogenic fungi investigated to evaluate functions. The from NPK...
With the depletion of global phosphorous (P) reserves, finding alternatives to P fertilizers has been gaining more and attention. This study was conducted identify whether biochar application could improve availability in a P-deficient alkaline alluvial soil. Unground contained high level 692 mg kg−1 extractable P, over 100 times than that Extractable content increased significantly with decrease particle size. There significant positive correlation between soil available rates. The pot...
Elucidation of the inhibitory effects humic substances (HSs) on phytopathogenic fungi and underlying molecular mechanisms are highly important for improved biocontrol. In this study, we investigated growth suppression, morphological characteristics, transcriptomic sequence, radical signals Rhizoctonia solani following HS addition (50 mg/L). Through mycelial cultured experiment, mycelia R. had been suppressed with addition, inhibition rate was 24.88 ± 0.11% compared to control. Field...
Abstract BACKGROUND Humic‐like substances (HULIS) for use in controlling soil‐borne diseases have been a research focus, but obtaining HULIS with high fungistatic activity via different extraction solvents has challenging. In this work, three were selected to extract from weathered coal. Inhibition rates against phytopathogens used evaluate the activities of HULIS. Element contents (C, N, S, and O) carbon‐13‐cross polarization magic‐angle spinning nuclear magnetic resonance ( 13 C‐CP‐MAS...
To select optimal fertilization management for soil productivity and fertilizer-nitrogen use efficiency (NUE) improvement in rice fields, we conducted a microplot experiment by growing soils from different long-term fertilizations with the same inorganic fertilizers. The NUE was accurately evaluated using 15N labeled urea. variations of chemical compositions organic carbon (SOC) under were investigated three-dimensional fluorescence measurement. results indicated that treatments containing...
