Rombola, Alessandro G.;Torri, Cristian;Vassura, Ivano;Venturini, Elisa;Reggiani, Roberto;Fabbri, Daniele published 《Effect of biochar amendment on organic matter and dissolved organic matter composition of agricultural soils from a two-year field experiment》 in 2022. The article was appeared in 《Science of the Total Environment》. They have made some progress in their research.Electric Literature of C14H22O The article mentions the following:
Dissolved organic matter (DOM) is an important organic matter fraction that plays a key role in many biol. and chem. processes in soil. The effect of biochar addition on the content and composition of soil organic matter (SOM) and DOM in an agricultural soil in Italy was investigated within a two-year period. UV-Vis spectroscopy and anal. pyrolysis have been applied to study complex components in DOM soil samples. Addnl., anal. pyrolysis was used to provide qual. information of SOM at mol. level and the properties of biochar before and one year after amendment. A method was developed to quantify biochar levels by thermogravimetric anal. that enabled to identify deviations from the amendment rate. The water-soluble organic carbon (WSOC) concentrations in the amended soils were significantly lower than those in the control soils, indicating that biochar decreased the leaching of DOM. DOM in treated soils was characterized by a higher aromatic character according to anal. pyrolysis and UV-Vis spectroscopy. Moreover, a relatively high abundance of compounds with N was observed in pyrolyzates of treated soils, suggesting that biochar increased the proportion of microbial DOM. The results from thermal and spectroscopy techniques are consistent in highlighting significant changes in DOM levels and composition due to biochar application with important effects on soil carbon storage and cycling. And 4-tert-Octylphenol (cas: 140-66-9) was used in the research process.
4-tert-Octylphenol(cas: 140-66-9) has been used as a reference standard for the determination of the analyte in water samples using ultra-high-performance liquid chromatography/tandem mass spectrometry (UHPLC/MS/MS).Electric Literature of C14H22O
