INTRODUCTION. The amount of organic matter (OM) is estimated as 10 16 tons of C, constituting the largest geological C pool on the earth's surface (González-Pérez et al., 2004; Arias et al., 2005).This amount is very high and restricts the humin (HM)/humic acid (HA) fraction present on the surface layer of farmed soil, totalling 1 500 × 10 9 tons. …Web

Humic substances (HS) are originated from naturally decaying biomass. The main products of HS are humic acids, fulvic acids, and humins. HS are extracted from natural origins (e.g., coals, lignite, forest, and river sediments). However, the production of HS from these resources is not environmentally friendly, potentially impacting ecological …Web
