Alkaline Cupric Oxide Oxidation of Roots and Alkaline-Extractable Organic Matter of Chernozemic Soils

Characterization of lignin by gas capillary chromatography of cupric oxide oxidation products

“…Lignin compounds are phenolic polymers that occur as major constituents of the cell walls of vascular plants (1). As a result of their natural abundance, wide distribution, and resistance to microbial degradation, lignins are also commonly found in soil and sedimentary organic matter (2)(3)(4)(5)(6).…”
