A simple, rapid and eco-friendly method has long been needed for evaluating the compost stability because application of unstable compost in agricultural field causes phytotoxicity. Thus, the CIELAB variables L*, a*, b*, a* x b*, a* / b*, 2000a* / (L* x b*), 1000a* / (L* + b*), chroma (C*ab), hue (hab) and color difference (∆E00) in dried (70oC) and ground composting materials (particle size ≤ ...

Soil carbon sequestration is strongly affected by soil properties, climate, and anthropogenic activities. Assessing these drivers is key to understanding the effect of land use on soil organic matter stabilization. We evaluated land use and soil depth influencing patterns of soil organic matter stabilization in three types of soil profiles located under the same pedogenetic matrix and alpine co...

Composts play an important role in the context of resource recovery and soil improvement by increasing soil organic matter. This study focuses on compost quality in terms of humic acid (HA) content which due to its favorable properties provides benefits for soils and plants. A series of Austrian and foreign composts (174 samples) were investigated to find out the level of HAs built up during co...

Seeking to evaluate the hypothesis that biochar optimises composting and vermicomposting processes as well their product quality, we carried out field greenhouse experiments. Four grass clipping treatments (only grass, + single superphosphate (SSP), SSP biochar) were evaluated. At end of maturation period (150 days), composts submitted (Eisenia fetida earthworm) for an additional 90 days. Ordin...

The Amazon Forest is an important and primordial ecosystem, as it controls the dynamics of soil organic matter (SOM) considered one crucial carbon reservoirs in world. Based on that, this study evaluated molecular properties humic (HA) fulvic (FA) acid from soil, with without Cu(II) ions, by Time-Resolved Laser Fluorescence Spectroscopy (TRLFS) (FS). excitation-emission matrix (EEM) was obtaine...

Taking aquatic processing waste as the main experimental object, to explore effect of different treatment conditions on humification process in acid-hydrothermal reaction process, through analysis hydrothermal pH value, organic matter and humus content, rate, infrared spectrum verification speculate formation mechanism humus. The results show that can promote a certain extent. Under working 195...
