Due to the complexity and heterogeneity of soil organic matter, a very wide range methods approaches is used study it. This generates an excessive number terms, definitions indices, which makes it difficult understand interpret data different authors. The paper provides overview currently most relevant for studying matter (SOM) its mineral matrix. review considers concept pools fractions, carbon saturation. main assessing content, structure, structure are described. estimation composition...
Structural peculiarities of the organic component dissolved matter (DOM) typical chernozems (Protocalcic Chernozem), dif ering in principal direction soil transformation (accumulation or mineralization), has been analyzed relation to mineral composition DOM. To characterize structural features component, spectrometry ultraviolet and visible range f uorescence spectroscopy were applied as approaches most en used for these purposes due expressiveness accessibility instrumental design. T e...
We studied the composition of water-extractable organic matter (WEOM) reclaimed soils (Novic Protocalcic Chernozems) in unplowed bottom dry valley and to compared it with WEOM plowed (Protocalcic on cropland small catchment. A layer-by-layer study was carried out from surface a depth 120 cm step 20 cm. Aqueous extracts were characterized by content carbon, nitrogen pH value. The optical properties assessed spectrophotometry fluorescence spectroscopy. Chernozems those sediments. features...
Soil-derived dissolved organic matter (DOM) has a significant impact on aquatic ecosystems. Identifying the fluorescence signatures of DOM from different soils in river and sea waters can provide valuable insights into its migration patterns. This makes crucial assessment pH, salinity, other parameters contribution to variability fluorescence. Present study investigates changes typical Chernozems under varying salinity using UV-visible spectroscopy coupled with parallel factor analysis...
Abstract Soil-derived dissolved organic matter (DOM) has a significant impact on aquatic ecosystems. Identifying the fluorescence signatures of DOM from different soils in river and sea waters can provide valuable insights into its migration patterns. This makes crucial assessment pH, salinity, other parameters contribution to variability fluorescence.
