Conventional wastewater treatment generates large amounts of organic matter-rich sludge that requires adequate treatment to avoid public health and environmental problems. The mixture of wastewater sludge and some bulking agents produces a biosolid to be composted at adequate composting facilities. The composting process is chemically and microbiologically complex and requires an adequate aerat...

The quality of soil organic matter plays a central role in structure, carbon sequestration and pollutant immobilization. effect 16–23 years fertilization on the was studied field experiments at ten experimental sites Central Europe. Soil samples were collected 2016 after barley harvest. Six crops rotated: pea–canola–winter wheat–spring barley–beet/potato–spring barley. treatments studied: unfer...

The composition, structure, and biological activity of humic-like substances (HLS) synthesized in the process lignosulfonate conversion for production humic product Lignohumate® (LH) were examined. It is shown that during hydrolytic-oxidative process, transformation raw material accumulation HLS occur. Data on chemical (elemental content, functional groups, FTIR) spectral (absorbance fluorescen...

Optical characterization of chromophoric dissolved organic matter (CDOM) from İzmir Bay (Aegean Sea) waters was investigated. For sampling, surface and subsurface seawater 7 stations were collected in summer 2015. Excitation-emission matrix (EEM) spectra each sample recorded on a fluorescence spectrophotometer. The results showed that carbon (DOC) concentrations EEM peaks increased the outer ba...

The organic matter of the soil and humus are heterogeneous in composition. That is why nature has not yet been fully understood causes many discussions. purpose this work to study identification features process peat's transformation. results a five-year experiment studying processes transformation organic-mineral substrate based on peat growing coniferous seedlings greenhouses presented. In dy...

Earthworm cast ageing controls soil ecosystem services such as carbon storage and nutrient availability. To test the hypothesis that biogeochemical changes during casts can be traced by infrared spectroscopy, we collected topsoil aggregates earthworm produced anecic Amynthas khami belonging to five distinct degradation stages in woodland northern Vietnam. We analysed mid-infrared (MIR) spectra ...

Time domain reflectometry (TDR) measurements of the volumetric water content (θ) soils are based on dielectric permittivity (ε), relating ε to θ, using an empirical calibration function. Accurate determination θ for peaty is vital but complicated by complexity organic and lack a general model. Site-specific models were developed determine from TDR heterogenous peatland across gradients peat dec...

Rice–wheat crop rotations have high carbon fluxes. A 2-year field study in Punjab, Pakistan quantified impacts of different nutrient management on harvestable biomass, crop-derived C, soil organic C sequestration (SCS), and decomposition. Treatments included combinations mineral fertilizer, animal manure (20 Mg ha−1), incorporated residue a split-plot design under conventional tillage (CT) redu...

The humic substance consists of acid, fulvic and humin. Humic acid is a useful metal complexing agent, good dispersant, redox agent. showed an auxin-like activity thus promoted root growth development. It positively affected soil’s physical, chemical, biological properties. Hence, indirectly improved plant by chelating nutrients to the plant. However, converted carcinogen compounds in chlorinat...
