Characterization of Humic Substance Extracted from Andisols, Spodosols, Peat, and Lignite
Sains Tanah: Journal of Soil Science and Agroclimatology, 2018 Soil and other materials with high C-organic content are potential natural sources of humic substances. Until now the differences in the characteristics of such humic substances that are extracted from different sources have not been widely studied. Thus,
