Water-Soluble Carbon in Soils (WSC)
摘要
Water-soluble carbon (WSC), the most mobile and bioavailable fraction of soil organic carbon, is extracted using deionized water, and its concentration is determined through oxidation with potassium dichromate in the presence of sulfuric acid, followed by titration with ferrous ammonium sulfate. Measuring WSC provides insights into the immediate carbon supply for microbial processes and its implications for soil fertility and sustainability.
