The quantity and quality of soil organic matter (SOM) depending on many edaphic environmental factors may change in response to agriculture-related practices. SOM humification process can be supported by the application mineral fertilizers, but production vineyards, such information is lacking. NPK fertilizer alters quality, therefore, aim this study was to: (1) assess extent dynamics different...

Urbanization has notably changed the characteristics and functions of watershed ecosystems worldwide, influencing chromophoric dissolved organic matter (CDOM) (DOM) sediments in urban streams. In this study, biogeochemical 42 water samples optical absorption excitation–emission matrix spectra (EEMs) 14 sediment collected from streams Wuhan were systematically examined. addition, five one sample...

Permafrost thaw in peatlands risks emitting vast stores of soil organic carbon (SOC) as greenhouse gases to the atmosphere, yet anoxic conditions and low peat quality may prevent rapid SOC loss. To assess differences anaerobic mineralization following vulnerability previously-frozen peat, we incubated (5° 14°C) from 15 depths ⁓6 m cores different sites including an intact permafrost plateau the...

The Little Ice Age (LIA) is a well-recognised palaeoclimatic phenomenon, although its causes, duration and severity have been matters of debate dispute. Data from wide range archives used to infer climate variability before, during after the LIA. Some published proxy-climate data peatlands imply that two particularly severe episodes within LIA may be contemporaneous between hemispheres; these e...

Forest soil biodiversity, which drives natural ecosystem multifunctionality, can be altered by incorrect forestry management practices. Pinus laricio is the most representative and widespread conifer species in Calabria, South Italy, appropriate needed to maintain forest for its great economic value. In Europe, thinning considered effective silvicultural treatment maintain/increase ecological v...

Abstract The mineralization and humification of organic matter triggered by added exogenous carbon are relevant to soil (SOM) turnover stability. Biochar (BC) artificial humic substance (A‐HS), two typical materials, have not been jointly applied seek improve the pool, which is contributed development A‐HS has yet used on a large‐scale. We surmise that dynamic interactions occurring in combined...

Aerobic composting is widely used worldwide as a natural process for handling human waste. Such waste often contains pharmaceutical residues from consumption, yet their impact on has not been studied. The aim of this study to investigate the antihistamine cimetidine (10 mg/kg, 100 mg/kg) aerobic feces. key results show that 10 mg/kg accelerates temperature increase and moisture removal substrat...

Abstract Background Spatio-temporal variations of structural components the POM–DOM fractions exhibit in urban rivers, which is valuable information to reveal dynamic migration and transformation within between organic matter pools, also provide important support for river water quality improvement management measures. Second derivative UV–visible spectroscopy (SDUVS) was applied simultaneously...

Seismic lines are prominent linear disturbances across boreal Canada with large-scale consequences to wildlife and ecosystem function. Although seismic line restoration has been observed improve tree growth survival, application in peatlands shown alter functions such as hydrology carbon storage. The most common active method is called mechanical mounding, where the classic technique inverts pe...

The biosphere organic matter is stored in nature various forms. Most of it associated with classical terrestrial organo-mineral soils. carbon woody plant biomass counted separately from soil as the standing biomass. Nevertheless, humification a universal process already begins residues before they reach surface tropical mineral soil. Moreover, humid-forest ecosystems, most does not at all and a...
